python赋值操作，当两个相同值赋给两个变量的时候，两个变量的地址是不一定一样的

#数字地址
a = 10
b = 10
print(a == b)
print(a is b)
print(id(a))
print(id(b), '\n')
print(a is b)
#列表地址
a = [10, 20]
b = [10, 20]
print(a == b)
print(a is b)
print(id(a))
print(id(b), '\n')
#字典地址
a = {'小明': 98, '小红': 96}
b = {'小明': 98, '小红': 96}
print(a == b)
print(a is b)
print(id(a))
print(id(b), '\n')
#集合地址
a = {98, 96, 92}
b = {98, 96, 92}
print(a == b)
print(a is b)
print(id(a))
print(id(b), '\n')
#元组地址
a = (98, 96, 92)
b = (98, 96, 92)
print(a == b)
print(a is b)
print(id(a))
print(id(b), '\n')

结果：

#数字地址
True
