Question

这是我的元组架构：

(name, age, weight)

UserList = (('steve', 17, 178), ('Mike', 19, 178),('Pull', 24, 200),('Adam', 15, 154))

我想检查年龄是否小于18我想用（,,）取代该用户的元组

因此最终结果将是

(('', , ), ('Mike', 19, 178),('Pull', 24, 200),('', , ))

我试过

UserList = list(UserList) 

for i,e in enumerate(UserList):
    if e[1] < 18:
        temp=list(UserList[i])
        for f, tmp in enumerate(temp):
            del temp[:]

但它不起作用，任何想法或建议都将受到高度赞赏。谢谢！

Answer 1

In [13]: UserList = tuple((n, a, w) if a >= 18 else ('', None, None) for (n, a, w) in UserList)

In [14]: UserList
Out[14]: (('', None, None), ('Mike', 19, 178), ('Pull', 24, 200), ('', None, None))

用空元组替换元组元组中的元素
