Python运算符公共操作

str1 = 'aa'
str2 = 'bb'

list1 = ['tom', 'jerry']
list2 = ['chris', 'gzy']

t1 = (10, 20)
t2 = (100, 200)

dict1 = {'name': 'gzy', 'age': 18}
dict2 = {'gender': 'boy', 'stu_num': 18152}

# +合并运算
print(str1 + str2)
print(list1 + list2)
print(t1 + t2)
# print(dict1 + dict2) 报错，字典不支持合并元素

# * 复制运算
print(str1 * 5)
print(list1 * 5)
print(t1 * 5)
# print(dict1 * 5) 不支持复制运算

# in,not in 判断是否在序列中,都支持
print('name' in dict1)
print('name' in dict1.keys())
