Like an art, code has a style too. This style is general guide if you want to learn how a developer writing a clean code and better readability. https://www.python.org/dev/peps/pep-0008

Pip

Pip is a Python Package Manager.

2. Execute: python get-pip.py
3. pip.exe and easy_install.exe files now should be located at: /PythonXX/Scripts (e.g. C:/Python27/Scripts)
4. Add /PythonXX/Scripts (e.g. C:/Python27/Scripts) directory into Path environmental variable.
5. Re-run terminal window
6. Type pip, to check if package manager works
