如何使用 Python 删除字符串中的重复单词?
问题描述
以下示例:
string1 = "calvin klein design dress calvin klein"
如何删除后两个重复的 "calvin" 和 "klein"?
How can I remove the second two duplicates "calvin" and "klein"?
结果应该是这样的
string2 = "calvin klein design dress"
仅应删除第二个重复项，并且不应更改单词的顺序！
only the second duplicates should be removed and the sequence of the words should not be changed!
解决方案
def unique_list(l):
ulist = []
[ulist.append(x) for x in l if x not in ulist]
return ulist
a="calvin klein design dress calvin klein"
a=' '.join(unique_list(a.split()))
