6. Python Special operators Python language offers some special types of operators like the identity operator and the membership operator. They are described below with examples. Identity operators In Python, is and is not are used to check if two values are located at the same memory location....
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 ...
(Identity Operators) An identity operator is used to check if two variables share the same memory location. 身份运算符用于检查两个变量是否共享相同的内存位置。 isandis notare identity operators. is和is not身份运算符。 isreturns True if the operands refer to the same object. Returns False otherwi...

# Identity operators x = [1, 2, 3] y = x z = [1, 2, 3] print(x is y) # True print(x is z) # False 7、成员关系运算符:这类运算符检查值是否为序列或集合的成员,它们包括in和not in。以下代码,通过“in”运算符指出2是列表numbers的成员,并以“not in”运算符指出6不是列表numbers的...
