在原始字符串 r'...' 中转义单引号 (') [英] Escape single quote (') in raw string r'...'

问题描述

我想打印出来

this is '(single quote) and "(double quote)

我使用以下(我想在这里使用原始字符串 'r')

I use the following (I want to use raw string 'r' here)

a=r'this is \'(single quote) and "(double quote)' 

但它打印出来

this is \'(single quote) and "(double quote)

在原始字符串中转义 ' 的正确方法是什么?

What is the correct way to escape ' in raw string?

推荐答案

引用自 Python 字符串文字文档、

当存在 'r' 或 'R' 前缀时，反斜杠后面的字符不加更改地包含在字符串中，并且所有反斜杠都保留在字符串中细绳.例如，字符串文字 r"\n" 由两个字符组成:一个反斜杠和一个小写的 'n'.字符串引号可以用反斜杠转义，但反斜杠保留在字符串中；例如，r"\"" 是一个由两个字符组成的有效字符串文字:a反斜杠和双引号.

When an 'r' or 'R' prefix is present, a character following a backslash is included in the string without change, and all backslashes are left in the string. For example, the string literal r"\n" consists of two characters: a backslash and a lowercase 'n'. String quotes can be escaped with a backslash, but the backslash remains in the string; for example, r"\"" is a valid string literal consisting of two characters: a backslash and a double quote.

有两种方法可以解决这个问题

There are two ways to fixing this

1. 使用多行原始字符串，如Python 字符串

print(r"""this is '(single quote) and "(double quote)""")
# this is '(single quote) and "(double quote)

使用字符串文字串联，

print(r"this is '(single quote) and " r'"(double quote)')
# this is '(single quote) and "(double quote)
