=== Python virtual environments ===

'''Use this'''

[https://docs.python.org/3/library/venv.html Python 3 docs]

'''Don't use the following'''

Setup Python virtual environment on Windows 10 using cmder in directory pydub

<pre>C:\Users\anon\Documents\python-venv           
λ python -m venv pydub                        
                                              
C:\Users\anon\Documents\python-venv           
λ ls -l                                       
total 0                                       
drwxr-xr-x 1 anon 197121 0 Nov 26 15:37 pydub/</pre>

Activate virtual environment. If you encounter an error about policy not allowing script, run <code>Set-ExecutionPolicy Unrestricted -Scope Process</code> then run activate script again.

<pre>C:\Users\anon\Documents\python-venv
λ .\pydub\Scripts\activate

C:\Users\anon\Documents\python-venv
(pydub) λ</pre>

Deactivate virtual environment

<pre>C:\Users\anon\Documents\python-venv
(pydub) λ deactivate
C:\Users\anon\Documents\python-venv
λ</pre>

To delete virtual environment just delete the directory used in <code>python -m venv</code> command (pydub in my example)
