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...
Below we have the names of the special functions to overload the relational operators in python. 下面我们有特殊功能的名称来重载python中的关系运算符。 It's time to see a few code examples where we actually use the above specified special functions and overload some operators. 现在该来看一些代...
=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"....
19.You can directly compare lists with the comparison operators like ==, <, and so on. 20.iterate with for and in 21.Iterate Multiple Sequences with zip() There’s one more nice iteration trick: iterating over multiple sequences in parallel by using the zip() function: >>> days = ...

- In Python, the comparison operators (`<`, `>`, `<=`, `>=`, `==`, `!=`) are non-associative. For example, the expression `a < b < c` is equivalent to `(a < b) and (b < c)`. For example : Python # Left-to-right associativity ...
If operators with different priorities are used, consider adding whitespace around the operators with the lowest priority(ies). Use your own judgment; however, never use more than one space, and always have the same amount of whitespace on both sides of a binary operator. ...
