why this is true?

(True > False) == False is false. True > (False == False) is false. why True > False == False is true?

True value is 1, False value is 0 1>0 == false // false.

My understanding for the last line is that when Python lets you combine comparison operators like that (WITHOUT using parentheses to make precedence explicit), it's a kind of syntactic sugar. So in Python something like: x > y == z really means: x > y and y == z but the first saves you some typing. And like Nahuel said, True and False behave like 1 and 0. So: >>> print(True > False == False) output: True is because: >>> print(True > False and False == False) output: True As an aside, the one exception to 1 and 0 for True and False is when you convert them to strings. >>> str(True) output: 'True'
