Below is a list of Characters in Python with escape character sequences. Many of these you will likely never encounter – so the common ones are marked. Conclusion If you have code that won’t execute due to syntax errors and can’t find the cause, comb through yourstrings and user input...
A raw string is a string that doesn’t translate the escape sequences. Any backslash characters are left in the string.Note: To learn more about raw strings, check out the What Are Python Raw Strings? tutorial.To create a raw string, you can precede the literal with an r or R:...
与上面对应的是,如果紧接字符能够和反斜杠构成'recognized escape sequences'的全部或者起始部分,中文就叫'被承认的转义序列'吧.比如: >>>'\b''\x08'>>>'\n''\n'>>>'\x'SyntaxError: (unicode error)'unicodeescape'codec can't decode bytes in position 0-1: truncated \xXX escape>>>'\N'SyntaxErro...
By default, decimal characters and alphanumerics from all alphabets are matched unless 'flags=re.ASCII' is used. It restricts special sequence matches to the first 128 Unicode characters and also prevents '\s' from accepting '\x1c', '\x1d', '\x1e' and '\x1f' (non-printable characters ...

ISO 2022为其支持的每个特定字符集分配一个特定的转义序列(escape sequence)。默认情况下,ISO 2022数据被解释为ASCII字符集;遇到任一转义序列时则以特定的字符集解释后续的数据,直到遇到一个新的转义序列或恢复到默认状态。ISO 2022标准旨在提供统一的编码格式,以期支持所有字符集(尤其是中日韩等东亚文本)。但其数据...
Escape sequences only recognized in string literals >>> '\u5120' '儠' #普通字符串会对\u转义,r不认 >>> r'\u5120' '\\u5120' 但即使在r-stirng里,引号也可以用反斜杠来转义,反斜杠仍然保留在结果中。 r"\"" is a valid string literal consisting of two characters: a backslash and a doub...
