python字符串轉(zhuǎn)義序列

First see, how escape sequence works?

首先看，轉(zhuǎn)義序列如何工作？

In the below example, we are using some of the escape sequence and their outputs, we are printing single quote (\'), double quotes (\"), printing path (double slash) (\\) and using hexadecimal values (\x).

在下面的示例中，我們使用一些轉(zhuǎn)義序列及其輸出，我們將打印單引號(hào)( \' )，雙引號(hào)( \“ )，打印路徑(雙斜杠)( \\ )并使用十六進(jìn)制值( \ x )。

Program:

程序：

#printing single quote str1 = "Hi, I\'m IncludeHelp" #printing double quotes str2 = "\"Hello world\"" #printing path str3 = "D:\\work_folder\\python_works" #using hexadecimal values str4 = "This is \x49\x6E\x63\x6C\x75\x64\x65\x48\x65\x6C\x70"print(str1); print(str2); print(str3); print(str4);

Output

輸出量

Hi, I'm IncludeHelp "Hello world" D:\work_folder\python_works This is IncludeHelp

忽略轉(zhuǎn)義序列 (Ignoring Escape Sequences)

To ignoring escape sequences in the string, we make the string as "raw string" by placing "r" before the string. "raw string" prints as it assigned to the string.

為了忽略字符串中的轉(zhuǎn)義序列 ，我們通過(guò)在字符串前面放置“ r” ，使字符串成為“原始字符串” 。 “原始字符串”將按分配給該字符串的方式打印。

Program:

程序：

#ignoring escape sequences#ignoring single quote escape sequences str1 = r"Hi, I\'m IncludeHelp" #ignoring double quotes escape sequences str2 = r"\"Hello world\"" #ignoring path escape sequences str3 = r"D:\\work_folder\\python_works" #ignoring hexadecimal values escape sequences str4 = r"This is \x49\x6E\x63\x6C\x75\x64\x65\x48\x65\x6C\x70"print(str1); print(str2); print(str3); print(str4);

Output

輸出量

Hi, I\'m IncludeHelp \"Hello world\" D:\\work_folder\\python_works This is \x49\x6E\x63\x6C\x75\x64\x65\x48\x65\x6C\x70
