Learn Python 2: Virtual Environments on Ubuntu Linux & macOS

Learn how to create virtual environments on Ubuntu Linux and macOS to keep your code well organized. Again, we cover manually creating venv, installing packages with pip and then virtualenvwrapper to help once you get serious about your Python coding.

i followed your video and was able to get tot to work. Yet i can not find were the virtual environments are placed so i can delete the ones i added. Nor can i find the one i want to keep. Can you share with me were they are placed. I created a directory called Firmware but there is nothing in it. thanks

Question: If I have an old laptop with Intel n2840 cpu, 8gb ddr3 ram and a 120gb ssd running Fedora linux.
Is it too slow to be used for learning Python?

If using oh my zsh, do you just edit .zshrc the same as .bashrc ? Thanks!

Virtualenvs for macOS and linux. If you're wondering why I've been tackling these first, all (should) be revealed in the next few videos.

When I try to install virtualenvwrapper on MacOS, it gives me the following:

Requirement already satisfied: virtualenvwrapper in (4.8.4)
Requirement already satisfied: virtualenv-clone in (from virtualenvwrapper) (0.5.6)
Requirement already satisfied: stevedore in (from virtualenvwrapper) (3.3.0)
Requirement already satisfied: virtualenv in (from virtualenvwrapper) (20.6.0)
Requirement already satisfied: pbr!=2.1.0, >=2.0.0 in (from stevedore->virtualenvwrapper) (5.6.0)
Requirement already satisfied: in (from (1.1.0)
Requirement already satisfied: filelock<4, >=3.0.0 in (from (3.0.12)

Requirement already satisfied: platformdirs<3, >=2 in (from (2.2.0)
Requirement already satisfied: six<2, >=1.9.0 in (from (1.16.0)

I added the script in .bash_profile but,
When I try "source ~/.bash_profile "
it says,

no such file or directory:

Is it conflicting with my conda installation? What do I do from here?
