Python Virtual Environment and pip for Beginners

[@garrettswenson794]

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

[@pravin9803]

Thanks a lot for such an informative and useful video. Learnt a lot of new things from this one video, than from multiple other videos. Also you are a great teacher. You have explained the points in a very simple and linear way. Appreciate it.

[@mback12000]

Very helpful video - thanks!

[@jakkdlaw]

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

[@liorp4640]

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")

[@jamescaleb9676]

awesome. best programming teacher on KZbin!

[@nirmesh44]

Great way to explain as always.

[@lenonfernandes8584]

You explain really well! Super easy to understand. I am literally learning python now and your videos are really easy to follow along. Do you teach Data Analysis as well?

[@ela2112]

Clear and complete. Nicely done. Thanks.

[@maxpopov6882]

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

[@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!

[@DaveGrayTeachesCode]

Good additions, Ahmad! I hope you are well my friend!

[@ahmad-murery]

@@DaveGrayTeachesCode little busy but I'm ok, and I hope you're well too. Thanks for asking my friend!

[@adriantworek1057]

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.

[@DaveGrayTeachesCode]

That's the plan! More Python coming after the beginners series.

[@kcell2042]

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

[@DaveGrayTeachesCode]

Thanks - it seems venv used to be and pipenv just got the recommendation in 2022. I won't double up on these in this series, but maybe another look in the future. The overall concept and goal works with either.

[@joohuynbae5084]

oh my gosh i'm dying to find the correct command, i've tried like 4 and none of them worked. i watch your video and get it right on my first try. thank you so much.

[@sholle7]

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?

[@abuzain859]

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

[@michaelscofield5343]

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

[@ram_qr]

brilliant as always

[@DaveGrayTeachesCode]

Thank you!

[@laurentgaume125]

Really Great

[@KutaibaAlnizaemy]

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

[@DaveGrayTeachesCode]

I do plan to. Thanks!

[@RichardThomas341]

Great tutorial! If I may add, at least in in Linux, "pip install" doesn't work, unless you are in a virtual environment (I forget the message). Globally, "pipx" must be installed and used.

[@tw9535]

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!

[@xzex2609]

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.

[@xzex2609]

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

[@quaternion-pi]

In windows terminal "source .venv\Scripts\activate", "source" was not recognized as a command. ".\.venv\Scripts\activate " starts virtual env. Great tutorial.

[@tamangteppiche8344]

How do i run this with source. It doesn’t work.

[@khalilbenmeziane8836]

i hope you do django series dave thank you

[@DaveGrayTeachesCode]

You're welcome!

[@lorenzasaettone8466]

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?

[@DaveGrayTeachesCode]

Nice suggestion! I have a Python Flask REST API tutorial coming up next week. The LLM addition might make a nice follow up.

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?

[@ledders27]

What am I doing wrong? Any help greatly appreciated. from dotenv import load_dotenv Import "dotenv" could not be resolved Pylance I've followed the steps of setting up the virtual environment, I can see in the requirements.txt python-dotenv=1.0.0. I'm using python 3.11.1. This also happens on lesson 23 with dotenv and flask.

[@raynlaze1339]

I have a solution for you guys: 1. Hit ctrl + p in vscode. 2. Type: >Python: select interpreter and select it 3. Click "Enter interpreter path..." 4. Enter the path or click "Find" and browse to the path to ".venv/Scripts/python.exe" (select python.exe) 5. check that this python.exe is now your selected interpreter, it should now work.

[@rebekkaruck961]

As someone with no experience in programming I found these videos really helpful and fairly easy to follow. With this one I have a problem and I was hoping someone could help me. I have successfully created the .venv file but after multiple attempts i still can't get it to activate. It keeps giving an error saying that "source" was not recognized as something that can be executed (or something like that). I tried google but nothing i found worked. I'm on windows using the current version of VS Code and the python extension. I'd really appreciate it, if someone could help me.

[@WildHeart7777]

I can't open up a virtual environment -- i get this huge error. I have the venv folder in the file explorer, and i can double click on activate to open it on my own, but I can't access it from the terminal. trying to figure out what I'm doing wrong :(

[@alkfjd6313]

I got the exactly same error. I saw someone on StackOverFlow saying that source only makes sense in Linux, so you can only use source in bash terminal. But bash terminal throws a "No such file or directory" error.
