从字符串中删除多个单词的更好方法? [英] Better way to remove multiple words from a string?

问题描述

bannedWord = ['Good','Bad','Ugly']

def RemoveBannedWords(toPrint,database):
    statement = toPrint
    for x in range(0,len(database)):
        if bannedWord[x] in statement:
            statement = statement.replace(bannedWord[x]+' ','')
    return statement

toPrint = 'Hello Ugly Guy, Good To See You.'

print RemoveBannedWords(toPrint,bannedWord)

输出是 Hello Guy, To See You. 了解 Python 我觉得有更好的方法来实现更改字符串中的几个单词.我使用字典搜索了一些类似的解决方案，但似乎不适合这种情况.

The output is Hello Guy, To See You. Knowing Python I feel like there is a better way to implement changing several words in a string. I searched up some similar solutions using dictionaries but it didn't seem to fit this situation.

推荐答案

这是一个使用正则表达式的解决方案:

Here's a solution with regex:

import re

def RemoveBannedWords(toPrint,database):
    statement = toPrint
    pattern = re.compile("\\b(Good|Bad|Ugly)\\W", re.I)
    return pattern.sub("", toPrint)

toPrint = 'Hello Ugly Guy, Good To See You.'

print RemoveBannedWords(toPrint,bannedWord)
