python - 删除所有非字母字符，保留字符串中的空格

Question

我不是程序员。我是一名艺术家，正在为我正在制作的艺术装置学习 Python。我已经在 Youtube 和 Stackoverflow 上做到了这一点。

也就是说……

我从 API 获取文本，然后将其显示在标签中。原始文本如下所示:

{"word":"hello","synonyms":["hi","how-do-you-do","howdy","hullo"]} , 单词根据用户输入进行更改。

我只想显示括号内的单词，没有标点符号。经过大量 Stackoverflow，我发现 re.sub(r"\W", "", text, flags=re.I)(天哪，我不知道这是什么意思，只是 w ,W 表示字母/非)。这给了我:

"wordhellosynonymshihowdoyoudohowdyhullo

叹息。如何保留我的空间？我想我可以自己去掉前 17 个单词。

完整代码(我很尴尬)。我知道它的一部分坏了，我一次扑灭一团火。最终项目是一个程序，它返回用户输入单词的同义词，然后询问用户输出是否正确。结果最终将显示在图表中。输出有时是故意错误的，我不需要修复它。

你得到的是一个 JSON 字符串。您需要解析 JSON。有一个图书馆。

import json
text = '{"word":"hello","synonyms":["hi","how-do-you-do","howdy","hullo"]}'
data = json.loads(text)
print(" ".join(data["synonyms"]))
