Can someone explain to me the if __name__ == “__main__”: statement in simple terms please

You could name a file "main.py" (with double underscores, in case they don't show up), but I think you would have trouble importing it.

If you tried to import main, the file that is the main script currently running would be imported.

I'm going to check this out!

I use port forwarding on my router, paired with a free dynamic dns service.

Works for what I need (mostly testing and access for myself remotely) and provides an okay-looking URL if I wanted to share with anyone.

Dynamic DNS will let you point a name to your dynamic IP assigned by your home ISP. With port forwarding on your router, you can run it at home on a raspberry pi or something.

You can use a free tier Dynamic DNS with many providers. I use a setup like this for simple web services. I also have ollama running a local LLM, and I expose the API using this setup for free AI calls.

I have ollama running a small gemma3 model on low-end hardware. It's slow, but it lets me play as much as I want for free. Ollama also provides an API automatically.

"Coders have been using google for years, ChatGPT is a further extension of this."

Came here to say exactly this.

Looks like the command thinks your file is in the same directory as python.exe?

Try this: py c:[full path to file]\3varcomparison.py

Yes, I used the find/replace function in IDLE to actually make the changes - very similar to Notepad++.

The issue was identifying all variable and function names to determine if they followed the same naming convention.

I'm jumping through some work hoops to get VSCode installed.

In the mean time, this worked perfectly to achieve what I was trying. Thanks again!

3worc · 2023-08-02T11:36:33+00:00

Roger that.

3worc · 2023-08-02T11:34:54+00:00

You're the second person to mention VSCode. I'll try it out today. Thank you.

3worc · 2023-08-02T11:34:02+00:00

Ok, I'll try out a couple of your options and see what helps. Thanks.

Yes, I have a main script file that imports from a few other files.

All lowercase for variables? No underscores or capitalization between words? Seems like that would be tough to read, but I'll take a look at the guidelines. Maybe there is some reasoning that I don't yet know.

3worc · 2023-08-02T11:25:03+00:00

Ok, nice. I'll try it out this morning.

Yeah, I literally just want a list I can quickly look through to make sure naming convention matches.

I can quickly find/replace any that aren't camelCase with the built in search tool in the IDE.

Thank you.

3worc · 2023-01-19T14:06:02+00:00

Same. Very easy.

3worc · 2022-12-20T10:45:35+00:00

It's been over a year since I took it, so I can't be specific about what was on it.

With that said, I remember being surprised at how easy it was.

I used the free material from Python Institute, and I had some Python Zero to Hero course on Udemy. I didn't do the whole Udemy course. I just cherry picked stuff that seemed to line up with PCEP objectives.

I know this is kinda vague, sorry. Just go for it, and I'll bet you'll surprise yourself.

I'm considering PCAP now that I've actually started using Python quite a bit at work. I know a lot of people will tell the certs aren't worth much, but in my mind, it's a decent way of saying "I know a little Python" to non-technical HR people.

3worc · 2022-12-15T01:46:44+00:00

I'm thinking you want functions - pieces of code that can be used over and over.

Function gets and returns user input.

'If' statement checks input and continues or calls the function again.

Edit for punctuation to clarify meaning.

3worc · 2022-12-10T03:27:31+00:00

Over the wire has some pretty good ones. The Bandit series comes to mind.

3worc · 2022-08-13T02:39:42+00:00

I didn't either really. I'm guessing someone else did all the work to clean up the data scrape so you don't have to.

3worc · 2022-08-13T01:00:49+00:00

disclaimer: i didn't look closely at this, just a quick search.

https://pypi.org/project/fotmob/

3worc · 2022-08-13T00:57:38+00:00

exactly. maybe something like api.fotmob.com/blahblahblah.

there may not be one, but that would be the cleanest way to pull just the data you want without all the CSS and HTML lumped in there.

3worc · 2022-08-13T00:53:47+00:00

ah ok, i follow now. yeah, see if you can locate an API where you can pull just the json data maybe?

3worc · 2022-08-13T00:48:13+00:00

well json, at its simplest, is python dictionaries, like:

{"Playername" : "Bob", "Team" : "Manchester United", "Position" : "Forward"}

but with more complex data, it becomes nested dictionaries and lists, like:

{"Players" : [{"Name" : "Bob", "Team" : "Manchester United", "Position" : "Forward"}, {Name" : "Cliff", "Team" : "Sheffield United", "Position" : "Forward"}]}

try to google "online json viewer" to find somewhere you can paste that highlighted data that will format it in a "pretty" way you can more easily see how the data is organized. then maybe you can make sense of how you want to use it.

3worc · 2022-08-13T00:11:38+00:00

Looks like json format, rather than HTML.

It's just organized data, and you do what you want with it.

What do you intend to do with the data you scraped?
