Comparison Operators and Expressions in Python Comparison of Integer Values Comparison of Floating-Point Values Comparison of Strings Comparison of Lists and Tuples Boolean Operators and Expressions in Python B
You’ll also find that special methods are behind comparison operators. For example, when you execute something like 5 < 2, Python calls the .__lt__() magic method. Here’s a summary of all the comparison operators and their supporting methods: OperatorSupporting Method < .__lt__(self,...
Comparison operators look at the numerical value of True and False 0 == False # => True 1 == True # => True 2 == True # => False -5 != False # => True 我们要小心Python当中的bool()这个函数,它并不是转成bool类型的意思。如果我们执行这个函数,那么只有0会被视作是False,其他所有数值...
我们用==判断相等的操作,可以看出来True==1, False == 0. # Comparison operators look at the numerical value of True and False 0 == False # => True 1 == True # => True 2 == True # => False -5 != False # => True 我们要小心Python当中的bool()这个函数,它并不是转成bool类型...

=operators: objects of different incomparable types always compare unequal to each other. builtin.sorted()andlist.sort()no longer accept thecmpargument providing a comparison function. Use thekeyargument instead. N.B. thekeyandreversearguments are now "keyword-only"....

Comparison operators: ‘==’ (equals), ‘!=’ (not equal), ‘>’ (greater than), ‘<’ (less than), ‘>=’ (greater than or equal to), ‘<=’ (less than or equal to). For example: is_equal = 5 == 3 # Compare whether it is equal or not, the result is False is_greate...
