在python中格式化无序字符串

Question

我有一个像......这样的字符串。

"1" "2" "3" "4" " " "text1" "text2" "text3" "6" "first && second && third.." " " " 7 " "         8"..  

我打算实现的是......

 1,2,3,4,,text1,text2,text3,6,first && second && third..,,7,8,..  

任何人都可以帮我解决这个问题吗？

如果你有一个列表字符串，那么去除空格的每个元素并使用str.join()将它们与分隔符连接起来：

','.join([s.strip() for s in list_of_strings])

演示：

>>> list_of_strings = ["1", "2", "3", "4", " ", "text1", "text2", "text3", "6", "first && second && third..", " ", " 7 ", " "]
>>> ','.join([s.strip() for s in list_of_strings])
'1,2,3,4,,text1,text2,text3,6,first && second && third..,,7,'
