第8节--python数据结构--tuple

元组（tuple)

创建

#create tuplenumber_tuple = (1,2,3)string_tuple = ("hello","nihao","doubi")mixed_tuple = ("world",100,"weixin")print(number_tuple[0])print(string_tuple[1])print(mixed_tuple[2])

不可更新

#update tuple# number_tuple[1] = 111# print(number_tuple)

不可删除tuple中的元素，可以删除整个tuple

# delete tuple item# del mixed_tuple[2]  不可以删除tuple里的元素# print(mixed_tuple)  # delete tuple# del mixed_tuple     可以删除整个tuple# print(mixed_tuple)

脚本操作符

#lengthprint(len(number_tuple))#combinationprint(number_tuple+string_tuple)#repeatprint(("hello ")*4)#existprint(3 in(1,2))#tuple cutabcd_tuple = ('a','b','c','d')print(abcd_tuple[1])print(abcd_tuple[2:])print(abcd_tuple[-2])
