通过 python 正则表达式删除包含特殊字符的字符串

Question

我的代码：

s = '$ascv abs is good'
re.sub(p.search(s).group(),'',s)

输出：

'$ascv abs is good'

我想要的输出：

'abs is good'

我想通过 python 正则表达式删除包含特殊字符的字符串。我以为我的代码是正确的，但输出是错误的。

如何修改我的代码以使输出正确？

Answer 1

invalid_chars = ['@'] # Characters you don't want in your text

# Determine if a string has any character you don't want
def if_clean(word):
    for letter in word:
        if letter in invalid_chars:
            return False
    return True

def clean_text(text):
    text = text.split(' ') # Convert text to a list of words
    text_clean = ''
    for word in text:
        if if_clean(word):
            text_clean = text_clean+' '+word
    return text_clean[1:]

# This will print 'abs is good'
print(clean_text('$ascv abs is good'))
