This is great ! Thanks !
For the weather example - I also added a "raise" exception" (following your exception tutorial) in case a city is not found ( weather_data["cod"] == "404")

perfect tutorial, you really saved me today. The confusion from today's class is gone.

All I needed was to figure out how to install packages on vsc since I only ever used pycharm for months and this was the first video that actually showed me that you have to tap in to "py -m" first, no other videos showed that, so thank you

[maxpopov]

So glad that I stumbled on your channel. Than you very much good sir!

i am learning python from udemy when i get stuck I come to Youtube and search for my favorite content creator Dave Gray to find asolution 😍😍

[ahmad-murery]

You may want to add pip directory to the *Path* system environment variable, this way you can call it directly without adding *py -m* in front of it.
I prefer using the *source* command unless I'm in a bad mood I'll use the dot (.) as a shortcut

Thanks Dave!

[ela]

Clear and complete. Nicely done. Thanks.

[kcell]

Appreciate.
The official Python recommendation is pipenv. I'm also looking forward to the Pipenv lesson.

Amazing work Dave! Thank you for this series. I hope you will record some web development stuff with Python (Django or FastAPI) in the near future.

[michaelscofield]

thanks sir, if you could explain some python modules after ending this course ❤.

[sholle]

Hi Dave! This was very helpful. I am a Python beginner and I find that you explain things that a lot of instructors forget (the curse of knowledge). I do have a question though. As you were typing in the function it showed it created a test. Can you tell me what extension you are using? And do you have any suggestions on extensions?

[jamescaleb]

awesome. best programming teacher on YouTube!

Damn that's so good! Thank you so much for your time and teaching style! A+

On the virtual environments, if the .py file is stored/run from a different environment (or anyplace else), is there a way at the top of the script to force it to use the python.exe and dependencies in THIS one-- the one (virtual environment) that we just created?

That is something about virtual environments that I am not clear on yet.

Thank you!

thank you for your Great work, I think one thing was not clarified at the end and we creates some .gitignore and .env files to protect our API KEY but in the end I didn't understand the next step is just commit the project to git hub ? or there is more to it ? I appreciate if some one help me understand it.

[khalilbenmeziane]

i hope you do django series dave thank you

[xivckqe]

Do you think of creating a NestJS course? We hope so.

[johnforeverrules]

hello dave sir. after python series, are you going to teach django or flask(or both)? thanks in advance for your reply

[xzex]

In windows I could never activate the venv with Source, I just run the activate.bat .

[placidaorlunwo]

I am having challenges installing pakages to the .venv. After I activate and install the installed package doesn't appear in the library. Please how can I resolve this?

[lorenzasaettone]

can you prepare a quick tutorial about a web app with flask and API by llm openai. The goal is to answer right to a quiz, and got checked answers, which are not simple yes or nos or fixed words?
