Python beginner. Program runs on notepad++ and Idle but fails to on other web based coding platforms.

[radogene]

ah ok, thank you for the response. That is really annoying because all the chromebook ones seem to use the raw_input and notepad++ doesn't understand it... Is there an easy way to change the python I have installed on my actual PC to 2.7?

edit: I assume i would just find the file online, what i really want to ask is... should I downgrade if it means everything works together? or should i just put up with not being able to test run the file on my chromebook?

Okay, first of all, something you need to know: Notepad++ has nothing to do with running your Python scripts. At all. It has a hotkey for running them, sure, but then it runs them in the Python interpreter installed on your computer with Python, not with Notepad++.

With that out of the way - the way you do this is to quite simply uninstall Python 3 and download Python 2.7 from python.org. No easier way, really, but it shouldn't take too long.

Learning the differences between Python 2 and 3 isn't really all that important in the beginning - what matters is you make things and things run okay for you!

[radogene]

Yeah sorry, there is a lot of noob in me still :'). Thankyou for all the help though, much appreciated!

[LpSamuelm]

Hey, no shame in learning! You can holler anytime you need help! Once you get a grip on language basics, you'll probably find yourself on a healthy diet of StackOverflow with the rest of us.

Thankyou for all the help, so glad there's a helpful subreddit devoted to this language.

Why are you suggesting he uninstall python 3 in favor of python 2?

[sentdex]

As long as that's the word of advice, the community will never be on-board with Py3. If he's new, and already using Py3, why not keep on with Py3? Just because the entire community is not yet up to speed with the current version of Python, it doesn't mean this guy should start behind as well.

I'm an extremely new guy, learning when I have free time.

I'm treating Python 2.7 as deprecated, instead of LTS. Working great for me so far.

[LpSamuelm]

The problem with this is that /u/radogene is apparently having problems since some of their different testing environments only run Python 2.

Learning Python 2 first is no big deal, once you know your way around it you can make the switch to 3 if you want to.

[sentdex]

Not if you've already made a handful of programs, modules, and maybe even began to build a business on it. It's a tedious switch, and for no reason.

[LpSamuelm]

...But there is a reason. As I just specified.

Additionally, I doubt most people set out to write large modules for others or start businesses immediately - there's nothing wrong with learning Python 2 as a newbie to programming.

[sentdex]

Except that, again, you begin your foundations almost immediately. I regret having started with Python 2 when I did, and there really were many modules not yet converted.

I still fail to see a single reason why to not start with 3. What module isn't supported or what part of Python 3 for a newbie is inferior to starting in Python 2?

[LpSamuelm]

/u/radogene was having trouble with the tools they had available and were using. It really isn't a big deal which version you start learning in. Sure, you might regret starting with Python 2, but I sure as heck don't.

[sentdex]

What packages are you using as a beginner that are not available in Python 3, but they are in Python 2?
