A Python String object is immutable, so you can’t change its value. Any method that manipulates a string value returns a new String object. The examples in this tutorial use thePython interactive consolein the command line to demonstrate different methods that remove characters. Remove Characters...
s = ''.join(filter(str.isalnum, s)) This will take every char from the string, keep only alphanumeric ones and build a string back from them. Share Improve this answer Follow edited Feb 28, 2020 at 8:01 answered Jan 5, 2015 at 5:16 Don 17.5k1212 gold badges6666 silver badg...

这种方法使用列表推导来简化代码,其逻辑与暴力解法相似,但是在 Python 中,列表推导通常比相同逻辑的循环更快。 defremoveVowels(s:str)->str:vowels="aeiou"return''.join([charforcharinsifcharnotinvowels]) 复杂度分析: 时间复杂度:O(n),必须遍历整个字符串。
