name_tuple (zhangyanlin,suoning,nick)
print(name_tuple.count(zhangyanlin))#index获取指定元素的指定位置
name_tuple (zhangyanlin,suoning,nick)
print(name_tuple.index(zhangyanlin))四.索引 name_tuple (zhangyanlin,suoning,nick)
print(name_tuple[1])五.切片 #取出第一位到最后一位减1的元素
name_tuple (zhangyanlin,suoning,nick)
print(name_tuple[0:len(name_tuple)-1])六.总长度len #取出最后一位减1的元素
name_tuple (zhangyanlin,suoning,nick)
print(name_tuple[len(name_tuple)-1])七.for循环 name_tuple (zhangyanlin,suoning,nick)
