我试图从使用Python 3中的正则表达式的文本文件中的wiki标题转储中提取英文标题.Wiki转储包含其他语言的标题和一些符号.以下是我的代码:
with open('/Users/some/directory/title.txt', 'rb')as f:
text=f.read()
letters_only = re.sub(b"[^a-zA-Z]", " ", text)
words = letters_only.lower().split()
print(words)
但我收到一个错误:
TypeError: sequence item 1: expected a bytes-like object, str found
在线: letters_only = re.sub(b"[^a-zA-Z]", " ", text)
但是,我使用b''输出作为字节类型,下面是文本文件的示例:
