Python仅保留列表中的字母数字单词 [英] Python keep only alphanumeric words from list

问题描述

我有类似以下内容的单词列表

I have a list of words resembling the following

    mylist=["hi", "h_ello", "how're", "you", "@list"]

我想提取所有非字母数字字符以给出如下结果:

I would like to pull out all of the non-alpha numeric characters to give a results such as:

                  "h_ello", "how're", "@list"

请注意，我在现实生活中的清单要长得多，它包含一些非字母数字实例，例如〜，?，>，=，+等.

Please note I have a much longer list in real life, and it contains some non-alpha numeric instances such as ~, ?, >, =, + etc.

有人知道怎么做吗? 谢谢

Does anyone know how to do this ,please? Thank you

推荐答案

使用str.isalpha()

例如:

mylist=["hi", "h_ello", "how're", "you", "@list"]
print([i for i in mylist if not i.isalpha()])

输出:

['h_ello', "how're", '@list']
