backslashreplace(仅限编码):使用 Python 的反斜杠转义序列替换无法编码的字符。 # 假设我们有一些带有非法字符的字节串 byte_string_with_error = b'Hello, \x80 World!' # 忽略错误 decoded_ignored = byte_string_with_error.decode('utf-8', 'ignore') print(decoded_ignored) # 输出: Hello, World!
re.sub( r"\\\w+\s*", # a backslash followed by alphanumerics; '', # replace it with an empty string; input_string # in your input string ) >>> re.sub(r"\\\w+\s*", "", r"\fs24 hello there") 'hello there' >>> re.sub(r"\\\w+\s*", "", "hello there") 'hello...

In a usual python string, the backslash is used to escape characters that may have a special meaning (like single-quote, double-quote, and the backslash itself). >>> "wt\"f" 'wt"f' In a raw string literal (as indicated by the prefix r), the backslashes pass themselves as is ...
