Python元组运算符

Python元组运算符：

len(元组名)：

返回元组对象的长度

# len(元组名)：
# 返回元组对象的长度
tuple_1 = (1,4,5,2,3,6)
print(len(tuple_1))
# 6

+ 连接：

#  + 连接
tuple_1 = (1,4,5)
tupel_2 = (3,5,4)
print(tuple_1 + tupel_2)
# (1, 4, 5, 3, 5, 4)

 * 重复：

# * 重复
tuple_1 = (1,4,5)
num = 3
print(num * tuple_1)
# (1, 4, 5, 1, 4, 5, 1, 4, 5)

成员运算符 in ，not in：

# 成员运算符 in，not in
tuple_1 = (1,4,5,2,3,6)
print(4 in tuple_1)
# True

print(8 in tuple_1)
# False

print(4 not in tuple_1)
# False

print(8 not in tuple_1)
# True

将元组作为可迭代对象：

# 将元组作为可迭代对象
tuple_1 = ('a','b','c')
for i in tuple_1:
    print(i , end = "  ")
# a  b  c
