+How to launch a python script, the right way

+# There's only 1 correct way of doing this, shown below.

+    
+# In short a python script can be devided in 3 parts.
+# Imports, definitions, directly executable.
+# Only your main file should contain these 3 parts/sections. Any imported file should only contain the first 2
+# parts. This prevents you from running a file that's only supposed to be imported, directly from terminal.
+# Your main file must follow this setup. Failing to do so, will give you issues further down the path.
+
+# The overall purpose of this setup is that the file you execute with python, is called "__main__" and
+# any other files is called by their import name.
+
+# Any code definitions are not executed until you actually call the function/method.
