Does anyone know how to do convert from a string to a boolean in Python? I found this link. But it doesn't look like a proper way to do it. I.e. using a built in functionality, etc.

EDIT: The reason I asked this is because I learned int("string"), from here. I tried bool ("string") but always got True.
