Text version of the video:

2:55 I used "bash" for activating my environment because it did not work the way you showed. The steps would be:
1. Open your terminal
2. Write "python3 -m venv work" and press enter
3. Write: "bash" and press enter
4. Write: "source work/bin/activate" and press enter
I don't understand it but now you should be in the work environment

Thanks so much.I had no idea the a <work> environment was available and easy to establish.

I use a MacOS Catalina, and I followed what you presented here and can now run a Python 3 code written by a colleague. Thank you! However, a directory named "work" was created on my Desktop. What can I do with this directory? Can I move it somewhere else?
