[英]Trying to replace punctuation with re.sub but getting error
我在另一个项目上使用 re.sub 取得了成功,但在这个项目上却没有,我不知道为什么。 它不断出现此错误,我不确定它的确切含义。
这是我遇到问题的代码:
import re
def a(sentence):
sentence=sentence.lower()
sentence=sentence.split()
sentence = re.sub(r'[!@#$%&*?]','',sentence)
print(sentence)
return
---我得到的错误:
def sub(pattern, repl, string, count=0, flags=0):
"""Return the string obtained by replacing the leftmost
non-overlapping occurrences of the pattern in string by the
replacement repl. repl can be either a string or a callable;
if a string, backslash escapes in it are processed. If it is
a callable, it's passed the Match object and must return
a replacement string to be used."""
return _compile(pattern, flags).sub(repl, string, count)
sentence.split()
创建一个列表,而re.sub()
需要一个字符串。 为什么要拆分?
