The "print" operator prints out one or more python items followed by a newline (leave a trailing comma at the end of the items to inhibit the newline).A "raw" string literal is prefixed by an 'r' and passes all the chars through without special treatment of backslashes, so r'x\nx...
Note: To learn more about raw strings, check out the What Are Python Raw Strings? tutorial.To create a raw string, you have to prepend the string literal with the letter r or R:Python >>> print("Before\tAfter") # Regular string Before After >>> print(r"Before\tAfter") # Raw ...
Python prints your raw string literal without considering \n a special character sequence anymore. In other words, a raw string literal always looks exactly as it’ll be printed, while a standard string literal may not.Raw strings are a convenient tool in your arsenal, but they’re not the...
虽说raw string能使 反斜杠 失去 转义的作用,但是,引号仍然能被转义,同时 反斜杠 仍然保留在字符串中 str1 = r"\"" # 正确 print(str1) str2 = r"\" # 错误 1. 2. 3. #str_single_quotes = 'H:\python\project\python\pb_basic\\tr\' # SyntaxError: EOL while scanning string literal str_...

escapes in raw strings are not treated specially. For example, r'\u20ac' is a string of 6 characters in Python 3.0, whereas in 2.6, ur'\u20ac' was the single “euro” character. (Of course, this change only affects raw string literals; the euro character is '\u20ac' in Python 3.0...

Python 2里的Unicode字符串在Python 3里即普通字符串,因为在Python 3里字符串总是Unicode形式的。 Unicode原始字符串(raw string)(使用这种字符串,Python不会自动转义反斜线"\")也被替换为普通的字符串,因为在Python 3里,所有原始字符串都是以Unicode编码的。

本篇我们介绍一下 Python 中的原始字符串(raw strings ),它可以将字符串中的反斜线当作普通字符处理。 原始字符串 在Python 中,以字母 r 或者 R 作为前缀的字符串,例如 r'...' 和 R'...',被称为原始字符串。与常规字符串不同,原始字符串中的反斜线(\)是一个普通字符,不具有转义功能。 原始字符...
