Python身份运算符
身份运算符用于对对象执行比较操作，即这些运算符检查两个操作数是否引用相同的对象（具有相同的存储位置）。
以下是身份运算符，
语法：
operand1 is operand2
operand1 is not operand2Python“是”运算符示例
#Python程序演示
#身份运算符的示例
x = [10, 20, 30]
y = [10, 20, 30]
z = x
#使用==运算符比较值
print("x == y: ", x == y)
print("y == z: ", y == z)
print("z == x: ", z == x)
print()
#比较对象
#他们是否在指
#是否相同
print("x is y: ", x is y)
print("y is z: ", y is z)
print("z is x: ", z is x)
print()输出：
x == y: True y == z: True z == x: True x is y: False y is z: False z is x: True
Python“不是”运算符示例
#Python程序演示
#身份运算符的示例
x = [10, 20, 30]
y = [10, 20, 30]
z = x
#比较值
#使用！=运算符
print("x != y: ", x != y)
print("y != z: ", y != z)
print("z != x: ", z != x)
print()
#比较对象
#他们是否在指
#是否相同
print("x is not y: ", x is not y)
print("y is not z: ", y is not z)
print("z is not x: ", z is not x)
print()输出：
x != y: False y != z: False z != x: False x is not y: True y is not z: True z is not x: False
