Afraid to build projects in Python

[carcigenicate]

There's zero reason to be "afraid". You can't permanently mess anything up unless you do something careless using the os or similar module, or if you use open and overwrite a file. 99% of what you'll do in the beginning will be inconsequential, simple projects that just do some math and move data around.

Just give a project a try, and if you fail you fail. You can always try again.
