Why True/False is capitalized in Python?
PythonCamelcasingPython Problem Overview
All members are camel case, right? Why True/False but not true/false, which is more relaxed?
Python Solutions
Solution 1 - Python
From Pep 285:

This, as Andrew points out, is probably because all (most)? built-in constants are capitalized.
Solution 2 - Python
All of python's built-in constants are capitalized or [upper] CamelCase:
Solution 3 - Python
Here's a possible explaination:

Solution 4 - Python
In python only the 3 keywords True ,False and None are started with capital letters. I think This is to differentiate these 3 keywords from others. These 3 keywords can be used as literals or values where as other keywords not. For example
a=True is correct but a=for is wrong
