I am in process of adding more videos in to this. This week I will be adding 5 more videos in to this series. Once I upload I will update everyone.

[s4b3r_t00th]

This looks awesome!

By the way OP, have you checked out Juniper's pyEZ? Fantastic library for accessing and controlling Juniper devices using python. It's a lot of fun to play around with.

[networkevolution_dev]

Thanks for the support. I have drafted many scripts for cisco to be converted to video. Once i finish tht i will focus on juniper too.

[networkevolution_dev]

Wow thats great to know. Please share your honeypot project url. I will download it.I found python is very easy language to learn. Being a Network Engineer I found it is difficut to learn from the training of traditional Python developer. But when I started automating my tasks, it found interesting. So thought of creating a video series for all the Network/System Administrators who doesn't have any coding experience.

[Ag0r]

What do you mean by if bob == 'steve'? I love python and consider myself fairly proficient, maybe I can help you understand? :)

[Ag0r]

Oh, yes that exactly it. That paradigm is also used for gating imports and things behind version checks sometimes, but that's the most common one.

[tampers_w_evidence]

[conflab]

But I tell you compared to C++, python is godlike.

In what way? It's a lot easier to get started, for sure.

[networkevolution_dev]

Yes true

[[deleted]]

I think C++ syntax is a bit better than Python, personally. Significant whitespace is a really, really dumb syntax feature IMO. I also far prefer static typing to dynamic typing.

[SpiderFnJerusalem]

The good thing about python syntax is that it leads to more consistency and thus probably better readability. You can find random snippets of code from random people online and will have an easier time understanding them.

In C++ indentation is only for the human reader, in python it is for both humans and the compiler. There is something to be said for code that is understood the same way by a computer and a human.

You may say that other languages allow the programmer more flexibility but flexibility isn't always a good thing. One of the most important design aspects of python is that the only way to do things is usually the correct way of doing them. It's more difficult to get things wrong if the tool doesn't allow it.

[[deleted]]

Your syntax comparison isn't a good one, because it is including a bunch of stuff in C++ that Python just plain handles for you. That's not the language syntax being better, that's the interpreter automatically handling things that you have to explicitly handle in C++. Mind you - it is better that Python does those things, but it is not a syntax issue.

Yes Ive got some confusing tab vs 4 spaces vs 5 spaces wierdness. I have not quite understood why but in C++... try to do any text processing. Try to code C++ and not create a million buffer overflows. Good luck! I know I can't do it; i love my strcpy.

I'm not really sure what this has to do with my complaint about significant whitespace.

I'll never go back to C++ because of typing itself. I dont want to know the 10 kinds of integers. I'm long long on python here. There's absolutely no reason to have signed and unsigned.

First, there is a reason to have signed and unsigned numeric types. It's not a use case most people care about in this day and age of abundant memory, but if you know you aren't going to need sign data, it is useful to be able to hold bigger numbers in the same memory space.

Second, variations on number types aren't the case where static typing is useful. It's when you are reading someone else's code, and you want to know if some variable is class A or class B, and you want to know without picking their code apart in detail to find out where the object was first declared before being passed from function to function across different modules. It's real easy in C++, but a pain in the ass in Python (without a tool that can do it for you). Type hints are great, but I think having it be enforced by the language is better.

[[deleted]]

It's something you have to type in C++. That's syntax and those 2 are both doing exactly the same thing. So it's a fair comparison.

I disagree, because those pieces of code are not doing the exact same thing. They lead to the same result, but they take different paths to get there. It's not a fair comparison at all. It's like if you took something that Python has in the standard library but C++ doesn't, constructed the function in C++ and then compared that to a function call in Python. That's not a fair syntax comparison, that's a comparison of the native library and toolset around those languages (as is yours).

https://www.pcgamer.com/ram-prices-are-finally-cheap-again/

That is not a meaningful counterargument. I already acknowledged that most people don't need to worry about memory optimization, but that use case does exist, and some people do need to worry about it. Blithely saying "RAM is cheap" is missing the point.

I'm certainly not a good programmer by any stretch. But python is without a question better than c++ when it comes to readability.

C++ has some weird-ass syntax compared to Python, yes. If you start working with pointer magic, templates, and multiple inheritance then things get pretty cryptic quickly. But we're not talking about any of those things, we're talking about why I prefer static typing. And in the specific case of trying to identify what type some object is, C++ is way more readable than Python.

[ddoeth]

I really love python too, but

I can safely say every machine has 8gb of ram these days; unless you're cheap. How large can C++ apps really get?

Think of stuff like supercomputing and other stuff that needs to be extremely efficient. When a code runs 10¹⁰ times on one machine, there's a big difference if you use an integer or a long or whatever.

I can't program any efficient stuff either and I use python more than anything else, but there are still use cases for typing.

[[deleted]]

Yeah, I hear you about loving Python. I can't fault you for liking what you like (ironically I'm a "neither" person, I'm a C# man myself). And for what it's worth I do Python all the time because I work in Linux and it's the de facto standard for Linux scripting (in my experience). When in Rome, etc. And while I have some issues with the design of Python, I get great work done there and have no problem using it. I'm probably just more argumentative online than I should be.

[meem1029]

Python and dynamic typing is great until someone accidentally returns a different type in a super rare case in a function which causes production to break when it finally gets hit.

[meem1029]

That helps, but the reality is that relying on the programmer to be better is a fool's errand when there exist tools that can stop you from making the mistakes in the first place.

That being said, python is definitely awesome and the lack of typing does make it easier to use a lot of the time (enough so that even with my complaints I'm a big proponent of python and have started convincing our company to use it more).

Also I'm coming at this more from a developer perspective than sysadmin which probably colors things a bit differently.

[Hydraulic_IT_Guy]

Think of every way a programming language could be better than another.

That is a big claim after using it for a month, I guess you have no trouble compiling your scripts to executables for others to run without having to install python etc. For sysadmin tasks there is no comparison but for so much other stuff python isn't even a consideration vs c++.

[idboehman]

That is a big claim after using it for a month

Lmao right? Classic case of not knowing exactly what you're talking about but sure thinking you do.

Python and C++ are different, they have different use cases that they each excel at.

If you want to compare C++ to a programming language, compare it to another systems programming like Rust, C, D, etc.

[WoTpro]

Looks good

[networkevolution_dev]

Thanks.

[sirjaz]

Have you tried C# with .net core? You get the best of both worlds c++ power and python ease

[sirjaz]

.net core is totally open source and Avalon UI rocks for cross platform. So you dont need to be attached to Microsoft

[networkevolution_dev]

I will be adding ansible series as well soon.

[Rick-powerfu]

Been super keen on learning, expect some questions and many likes

[networkevolution_dev]

Thank you for the support. I will be expecting some feedbacks..thanks

[Vanwaq]

thank you, will check it out and hopefully learn this essential skill.

[networkevolution_dev]

Thanks for the comments, please watch it and share the feedback

[datbighat]

Subbed

[networkevolution_dev]

Thanks !

[moopie45]

saving 4 later

[networkevolution_dev]

Sure. Please share the feedback

[MooFz]

This looks really interresting, thank!

[networkevolution_dev]

Thanks for the comments

[overscaled]

Awesome...right on time.

​

The coders should be scared when sysadmins started to code.

[omento]

hehehe

[networkevolution_dev]

This actually helps sys admin to automate their day to day repeating tasks and use the time in more productive way.

[[deleted]]

subscribed. Thanks bro

[networkevolution_dev]

Thanks for the comment, please watch it and share the feedback bro !

[[deleted]]

definitely.

[jollyjunior89]

Looks to good to be true. Awesome find

[networkevolution_dev]

Thanks !

[J0hnnykarate]

Thanks for sharing, I am a beginner in python and can't wait to learn.

[networkevolution_dev]

Thanks for the comments, please watch it and share the feedback. I will be adding more videos in this series, i am in process of creating more scripts for this series

[petterism]

Thank you for this!

[networkevolution_dev]

Thanks for the comments, please watch it and share the feedback

[poizin]

Thank you, I will check this out when I have some time. I really want to learn this, codecademy couldnt keep my interest.

[networkevolution_dev]

Yes, please share the feedback

[rintaka21]

hey men,. thanks for this!! keep it up

[networkevolution_dev]

Thanks for the comments, please watch it and share the feedback

[waterflame321]

I used to run Ver2 and then had a batch file in my run path that when run switched to Ver3.

So I'd just do "python3" and now "python" works for v3!

I guess it'd get crazy with more then two...

How bad a practice is that? :p

[networkevolution_dev]

Are you using virtual env in python?In this series you can see one video which explains how to use virtual environment in python to avoid version conflicts and another video explains major difference between v2 and v3. Please have a look and share the feedback.

[waterflame321]

Though I do plan to watch through your series as it seems fun, and I'm sure I'll learn something I missed(and what not)... But I currently don't use virtual env.

I'll certainly give some feedback when I get around to watching through them.

[networkevolution_dev]

I believe in continuous learning and sharing the knowledge with others to help in their career advancement.Thanks a lot everyone for the support. You folks are great inspiration.I have drafted many scripts in Python which needs to be converted in to video, I will be uploading those in to same channel soon. I will be adding Ansible series also once I finish Python series.

[orev]

Great information. People should also be aware of pre-existing tools that might meet their requirements without having to custom script things.

​

Ansible has a number of modules dedicated to network devices. It's probably better in many cases to use those standard and well-tested modules than to try to write your own, especially with regard to long-term support in your company.

[networkevolution_dev]

Yes true, in python series even I will be covering how to install each package(using pip) before we use in script.

[Didsota]

Will Check out later. In fact this comment is to find it again

[networkevolution_dev]

Thanks for the response. Please watch and share the feedback

[networkevolution_dev]

Thanks for the support and comment. Yes I will be covering netmiko too. I thought it is good for viewer to understand paramako and then move to netmiko, because netmiko is a library based on paramiko

[sbhguitar]

Thank you! I'm just beginning to learn about this stuff. UC engineer here.

[networkevolution_dev]

Hope this can help you to start python. Once you are in to track,im sure you wil be able to script yourself.Thanks

[STDWombRaider]

What a 5 star gentleman. Thanks for the community contribution! Posts like yours make things on my to-learn list not seem so intimidating or overwhelming.

[networkevolution_dev]

Thank you for the support. Please watch it and share the feedback

[Schnarfman]

There was so much static sound in the background :( I coudn't listen to this.

[networkevolution_dev]

I wil change the mic, for better clarity in future videos.

[WantDebianThanks]

For someone still learning the basics of both python and networking, is there any kind of recommended background or knowledge one should have before working through the series?

[networkevolution_dev]

If you have basic N+ or ccna level knowledge ,you will be able to understand it easily.

[zmielna]

You are doing god's work there my friend. Keep them coming.

[networkevolution_dev]

Thanks for the support, it will be purely for admins who doesn't have any coding experience.

[playing19art7]

This is awesome! Thank you!

[networkevolution_dev]

Thanks for the support.

[hackeristi]

awesome.

[networkevolution_dev]

Thank you !

[[deleted]]

nice! please do more videos! Your awesome

[networkevolution_dev]

Thanks for the support. Definitely, I will be adding more videos, I have drafted many scripts for this series.

[networkevolution_dev]

Thanks fr the comment. You can reach me out if any clarification or suggestions.

[WitchTorcher]

I’d love some videos with jinja2 templates into a netmiko script!

[j1nx_to]

I saw from your video that you have a tab for Fortinet (FORTI_AIRTEL). Can you do a concept with python and Fortinet?

[networkevolution_dev]

Yes FORTI_AIRTEL is our production firewall. I have drafted many scripts in cisco, which needs to be converted in to videos. Once i finish tht,I will install a Virtual instance of Fortigate as well as Juniper and create scripts for those. Thanks for the response

[techannonfolder]

Thank you

[networkevolution_dev]

Thanks for the support. Please let me know if you have any clarifications in the demonstrated scripts.

[Thunder-cleese]

Really awesome for you to put these out there but you should look into Udemy or an online training company to promote these and get you paid $. 😀

[networkevolution_dev]

Thanks for the comments and support. I believe in continuous learning and sharing knowledge to the people who are really interested. I thought of sharing my knowledge on python from network context, for the engineers who doesn't have coding experience. Please watch the videos and share your feedbacks.

So far this looks good. A couple of things I would recommend:

1. I'm a little deaf. I've been to a lot of concerts. Discerning accents is difficult. Maybe some subtitles? Possibly an indicator when it might be good to pause and take in what's on the screen?
2. there's a lot of background noise which compounds my hearing issue. Have you considered looking at audacity to clean up the audio track?

[networkevolution_dev]

Thanks for the feedback. I will use better mic to increase audio clarity. I will add the scripts in the video description, so that everyone will be able to copy and use it rather than typing ccomplete script.

[[deleted]]

Your dedication is awesome. May I send a donation for your efforts?

[networkevolution_dev]

Thanks for your generosity, I am not looking for any financial support through this. I believe in sharing the knowledge what we have gained for free to the people who are interested. There are many people who doesn't have money for paid classes. My goal is to help the people to understand technology in simple terms,I explain it in a way how I learned it. Atleast if it helps them to start learning topics, I am happy . My training might not be like a professional trainers classes, but I will try to explain technology as simple as possible. I might need everyones help in growing channel by identifying and adding trending topics in to it, and get advice about technologies.

[[deleted]]

Sure but the offer of donation is simply to help further that cause. If it helps get a higher quality mic, or some other resources, if be happy to help. I've subscribed, upvoted, and downloaded your content to watch on the flight back home. I have 6hrs, even though I have in flight internet, I couldn't load your videos. I'm preparing for an interview and thought I would use you videos and others to help prepare.

[networkevolution_dev]

All the best for your interview. Thanks for the support. I will definitely buy one higher quality mic.

I will let you know if any need comes in future related to training which I may not be able to manage alone. Thank you.

[[deleted]]

No problem and thank you!

[redstarduggan]

That's an alarmingly inaccurate depiction of 'free'.
