What are the Python string escape characters
This article will explain in detail what Python string escape characters are, and the editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.
There are many python string escape characters. I found that the information on the Internet is not very complete. Here I have carefully sorted out all the python string escape characters, as follows:
\ 0 NUL null character ascii value 0
\ 1 SOH title start ascii value 1
\ 2 STX body start ascii value 2
\ 3 ETX body end ascii value 3
\ 4 EOT end of transmission ascii value 4
\ 5 ENQ request ascii value 5
\ 6 ACK receives notification ascii value 6
\ 7 BEL ring ascii value 7
\ a BEL ring ascii value 7
\ b BS backspace ascii value 8
\ t HT horizontal tab ascii value 9
\ nThe NL newline key ascii value is 10
\ v VT vertical tab ascii value 11
\ F FF feed key ascii value 12
\ r CR enter key ascii value 13
\ ">\ 'single quotation mark ascii value 39
\\ backslash ascii value 92
Tip: bold escape characters are very common, please remember, others are rarely used, you can check here when needed.
Note: adding r before the string cancels the escape representation, for example:
"\ t" is represented as string data-a tab with an ascii value of 9
R "\ t" is expressed as string data--\ t, that is, the symbol\ and the letter t itself.
"\ 1" is represented as string data-- SOH, with an ascii value of 1
R "\ 1" is represented as string data--\ 1, that is, the symbol\ and the number 1 itself. In addition, it is used to represent grouping 1 in regular expressions.
