Python 是否有从字符串（\u0410）中删除特殊字符的方法？

我正在尝试清理字符串，但删除特殊字符时遇到问题。已注意小写字母和删除\n

my_string = "\u0410\u041d\u041e\u0422\u0410\u0426\u0418\u042f: \n* Lectures \u2013 20 hours \n* Workshops \u2013 8 hours (these workshops are so designed as to provoke active student participation;"

预期结果：

"lectures 20 hours workshops 8 hours these workshops are so designed as to provoke active student participation"

是否有删除所有特殊字符（\u0410等）的方法？

提取单词（使用正则表达式），并：

输出

lectures 20 hours workshops 8 hours these workshops are so designed as to provoke active student participation

或者更好，正如@tobias_k所建议的，首先使用lower：

result = " ".join(re.findall(r"[a-z0-9]+", my_string.lower()))

---

或先降低，然后仅使用a-z

result = " ".join(re.findall(r"[a-z0-9]+", my_string.lower()))
