Why so complicated?

It's can be difficult to start,there is a lot of stuff that's is unfamiliar.
Here my tutorial of basic usage of Python 3 on Windows and Linux.
Windows Part-1, Part-2
Linux Part-1

I've learned that I'm not to sudo pip install on the Fedora platform as it will create clutter

Advice follow tutorial in link about pyenv,for Fedora
Example:

mint@mint ~ $ pyenv install 3.6.2
Downloading Python-3.6.2.tar.xz...
-> https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz
Installing Python-3.6.2...
Installed Python-3.6.2 to /home/mint/.pyenv/versions/3.6.2
  
# Make python and pip default to 3.6.2 or what version want to use
mint@mint ~ $ pyenv global 3.6.2
 
mint@mint ~ $ python
Python 3.6.2 (default, Jul 20 2017, 14:21:59) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()

Now will pip install something always work and installing to 3.6.2,no need for sudo.
Switching back to OS default is easy to,as pyenv is safe to use it do not mess with system Python.

mint@mint ~ $ pyenv local system
mint@mint ~ $ python
Python 2.7.12 (default, Nov 19 2016, 06:48:10)

Type "help", "copyright", "credits" or "license" for more information.
>>> 
mint@mint ~ $ python3
