python - 如何从Python列表中删除子字符串

Question

是否有任何列表理解技术可以更好地获得以下期望的结果

a = ['hello', 'world', 'hello world', 'hello world how are', 'hello india']

final = set()
for i in a:
    for j in [x for x in a if x != i]:
        if i in j:
            final.add(i)
list(set(a)^final)

Answer 1

更短但不一定更好:

print([x for x in a if not any(x in j for j in a if x != j)])

删除最终列表中的重复项(类似于问题中的行为):

print(list(set(x for x in a if not any(x in j for j in a if x != j))))
