Py_Modify

[mforootan]

• Make a new branch of gdc-docs, and modify any Python script that currently just prints to console so that it writes to a file.
• Add remarks explaining what the script does to the beginning of all of them (pretty much copy-pasting what's already in the documentation page into the script box).
• Make the sample file examples executable (so the user can simply copy-paste scripts, run, and see some output), as much as possible (using real examples); or clearly explain required changes.
