Question

我有list l=['abc','abcdef','def','defdef','polopolo'] 我试图删除其超链接已经在列表中的字符串。在这种情况下，结果应为：

['abcdef','defdef','polopolo']

我写了代码：

l=['abc','abcdef','def','defdef','polopolo']
res=['abc','abcdef','def','defdef','polopolo']
for each in l:
    l1=[x for x in l if x!=each]
    for other in l1:
        if each in other:
            res.remove(each)

但它似乎无法奏效。我已经读过，迭代它时我们无法从列表中删除。因此复制res。，而l是我的原始列表。提前致谢。

Answer 1

l=['abc','abcdef','def','defdef','polopolo']
print [j for i, j in enumerate(l) if all(j not in k for k in l[i + 1:])]
# ['abcdef', 'defdef', 'polopolo']

我们可以通过在

之前对列表进行排序来加快速度

l = sorted(l, key = len)
print [j for i, j in enumerate(l) if all(j not in k for k in l[i + 1:])]

作为@Ashwini Chaudhary mentions in the comments，如果要保留重复的字符串，则可以执行此操作

l = ['abc','defghi' 'abcdef','def','defdef','defdef', 'polopolo']
l = sorted(l, key = len)
print [j for i,j in enumerate(l) if all(j == k or (j not in k) for k in l[i+1:])]
# ['defdef', 'defdef', 'polopolo', 'defghiabcdef']
