Hello, i followed your instructions In the video to deploy a flask app in Ubuntu but It didnt work, It shows me the 403 forbidden error, im using plesk, does that Matter?
One small comment, venv folders are usually named .venv so that they are hidden, and they also should be part of your git ignore if you put them in the same folder as your .py files. I usually have the .venv folder a level up from the .git directory, so that there is no issue with commits if you forget to put them in .gitignore. Fantastic video as usual!
Great video! As a Python beginner myself, I think virtual environments should be the first thing to learn after the basics. Even if you're just messing around with some package you're trying out, it makes it so much easier to keep your projects organized. It also helps with learning further packages etc.. Want to learn Flask? Just make a new environment for it, keeping everything together and contained, without cluttering your Python installation(s).
Another awesome video. Corey Schafer 's channel and Tech With Tim are my two favorite Python channels, and of course you can learn a lot more then just python. Thanks for posting more great content.
Great video TIm! I honestly think this is the first thing that beginners should learn before even writing their first "Hello world". Knowing the best practice of how to correctly setup a project in programming language will reduce future headaches, and allow one to focus on writing code.
Wow. Gotta watch this again! I’m so grateful. Just learning to code a bit for fun but never quite could get the hang of it virtual environments. This cleared everything up. So glad I stumbled on your channel. Definitely a new subscriber.
Thanks for the great video. I was just learning about virtual environments via some python training I’m taking at work. We are slowly trying to migrate from being a SAS programming shop to using python to code. After watching your video, I learned some additional details that weren’t covered in that training. Got to add some of what you said into my class note. Appreciate the content you’re making. I’ve seen a few of your other videos and they’re always very clear and informative. Keep up the great work.
As beginner, after learning python basics, virtual environment is the next thing to learn. It will help you when start learning Django or Flask frameworks. Great video 👍👍👍
Hi Tim, again a very tutorial, thank you! I am really with you - anybody who can benefit from this tutorial probably should stick with venv because it is just there. It would be interesting for me, how the different tools relate and differ. I know that anaconda is oriented towards data science… but what does that actually mean? Anything I can do in anaconda I can’t do with venv? Another question: how do vscode and venv interact? A tutorial how to use environments in vscode and how to use the environment once programming is done. Also, how to handle the environment when I want to pull a project from git? Do I have to use the same tool the maintainer used to recreate the project‘s environment or can I still rely on venv? Thanks for your work, it is a very nice display for your paid course!
When you show the four common choices for virtual environments at <a href="#" class="seekto" data-time="91">1:31</a>, you seem to equate virtualenv with venv as the images display on screen. Beginners should understand that virtualenv is a third-party tool.
Nowadays it is difficult to work without virtual environments especially if you work on more than one Project at the same time. I like using pyenv because I can easily install new versions of Python and create or remove envs . pyenv has an interesting set of CLI commands.
I always had one question Tim. Hope you can clarify. Lets say I create two virtual environments A and B. I do a pip on both and install libraries like Numpy, Pandas, TF, sklearn on both A and B, will that not occupy disk space? Does that mean for every project we do locally, the disk space gets consumed not just for code but these duplicate libraries too ? Is there an option to share a library between two virtual environments (if same version is needed) ? Please clarify
Yes, every project you create in venv occupies its own disk space. And no, there is no such option to share same libraries between venvs for it makes no sense. You create venv to be isolated from other venvs so you should not and must not share any libraries berween them.
If you are concerned about disk space, then delete the virtual environment folder when you are done with the project. If you need to revive your project, you can run the requirements.txt to install the packages in the environment and get going.
Nice and informative video, but I do have a questions. How would/can I use git with this? Do I initialize a local git repository on the folder that contains the files of the virtual environment and make commits there. Or do I initialize the a local git repository inside the virtual environment? (I learned how to use git from your videos months ago, and now I just learned about this virtual environment which is another useful knowledge for me.) I just want to know how can I combine the powers/great features the git and virtual environment have. I hope you can reply even though this video is 3 month old.
question about the last part, if you dont save your source code in the venv, where do you save it? also what do you mean the venv file only stores the things related to the virtual environment
Great video. Thanks. I've got one question. Once I create the directory where the virtual environments are going to be, that is, inside my 'projects" directory in this case. Suppose I've written a script and I want to run it in a specific virtual enviroment. How do I do that? I Created a virtual environment and navigated to the directory where file was and ran it by typing "python3 name_of_the_file" from withing the virtual environment. Is that correct or that is not how I should do it.
Hi. Thanks a lot! How to use multiple versions of python on one machine? For some projects I need python 3.10 and for some 3.12. Do you recommend to use conda for this scenario or just install several version in OS and use python venv?
I don't know if this is because I have a newer version of python installed, but "python -m venv env" throws an error, and instead I'm doing "py -m venv env" and it does exactly what it is suppose to
Quick question - after creating a virtual environment, will my 'import' statements in my code automatically import the versions of the package that are installed in my virtual environment? Because I have some packages installed globally and in the virtual environment - I'm curious which version will get precedent. Also, is it entirely bad practice to install any packages globally? Should I uninstall all globally installed packages and only use virtual environments? Thanks!
Hello Tim, I've started to use Zed however virtual environments are not as easy to use as in vscode and even after looking through zed's docs i wasn't able to solve the issue, do you have any advice pls
@@crystyxn yup, -r FILENAME is the same as --requirement=FILENAME. Although recursive also makes sense as you have to go through all the entries in the file.
hello, i followed your instructions in your video to deploy a flask app in ubuntu, but it shows me the error 403 forbidden, so i need to know, your tutorial doesnt work if you are using plesk?, i already located the files with cd and made the arrengements with the wsgi file
Btw, "ls" didn't work for me (Windows), but "dir" worked. It was a quick google search for me, so no big deal, but just pointing it out for the other people who may have been initially confused by that.
