Python里有很多运算符(operator),这节就让我们来详细学一学。 注意:本文没有特别说明的地方,只考虑bool、int、float三种类型。例如“两边操作数类型相同时,得到的结果为操作数类型”这句话只需要考虑上述三种类型就可以了。 算术运算符 加运算符(plus,+) +运算符将两个数相加。例如1+2等于3,1.23+4.56等于5.79。

operator.pow(a, b) operator.pow(a, b) 对于数字 a 和 b,返回 a ** b。operator.rshift(a, b) operator.rshift(a, b) 返回a 右移 b 位的结果。operator.sub(a, b) operator.sub(a, b) 返回a - b。operator.truediv(a, b) operator.truediv(a, b) 返回a / b 例如 2/3 将等于 .66 ...
In Python, the "not equal" operator is used to compare two values and determine whether they are not equal to each other. It is represented by the symbol !=. The result of the comparison is a Boolean value: True if the values are not equal, and False if the values are equal. ...
OperatorOperationSample ExpressionResult == Equal to a == b • True if the value of a is equal to the value of b• False otherwise != Not equal to a != b • True if a isn’t equal to b• False otherwise < Less than a < b • True if a is less than b• False ot...
print(f'x is not equal to z = {flag}') # python is strongly typed language s = '10' print(f'x is not equal to s = {x!=s}') Output: When we use not equal operator, it calls__ne__(self, other)function. So we can define our custom implementation for an object and alter ...
Identity operators are used to compare the objects, not if they are equal, but if they are actually the same object, with the same memory location:OperatorDescriptionExampleTry it is Returns True if both variables are the same object x is y Try it » is not Returns True if both ...

The loop iterates over iterable while the conditional statement checks if the target value is equal to the current value. Note that the condition checks for object identity with is or for value equality with the equality operator (==). These are slightly different but complementary tests....
