python字符串转义序列

First see, how escape sequence works?

首先看，转义序列如何工作？

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，我们使用一些转义序列及其输出，我们将打印单引号( \' )，双引号( \“ )，打印路径(双斜杠)( \\ )并使用十六进制值( \ 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

输出量

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

忽略转义序列 (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.

为了忽略字符串中的转义序列 ，我们通过在字符串前面放置“ r” ，使字符串成为“原始字符串” 。 “原始字符串”将按分配给该字符串的方式打印。

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

输出量

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