==和is之间的区别是python中的运算符。
is和equals(==)运算符大致相同,但不相同。is运算符定义两个变量是否都指向同一对象,而==符号检查两个变量的值是否相同。
范例程式码
# Python program to # illustrate the # difference between # == and is operator # [] is an empty list list1 = [] list2 = [] list3=list1 if (list1 == list2): print("True") else: print("False") if (list1 is list2): print("True") else: print("False") if (list1 is list3): print("True") else: print("False")
输出结果
True False True
