How to convert number 1 to a Boolean in python

Question

I have seen similar questions asked, but none have answered my question. I am relatively new to python, and have no idea what i'm doing.

Answer 1

Use:

>>> bool(1) True >>> bool(0) False >>> int(bool(1)) 1 >>> int(bool(0)) 0 

Can convert back too.

Or a clever hack that could be quicker would be:

>>> not not 1 True >>> not not 0 False >>>  

Converting back:

>>> int(not not 1) 1 >>> int(not not 0) 0 >>>  

Answer 2

Only the following values will return False when passed as a parameter to bool()

• None
• False
• Zero of any numeric type. For example, 0, 0.0, 0j
• Empty sequence. For example, (), [], ''.
• Empty mapping. For example, {}
• objects of Classes which has bool() or len() method which returns 0 or False

Everything else returns True
