title: Python Escape Sequences
|
||
|
|
---
|
||
|
|
A list of escape sequences can be found <a href='https://docs.python.org/3/reference/lexical_analysis.html#strings' target='_blank' rel='nofollow'>here</a>
|
||
|

|

|
Escape sequences allow for including special characters into strings.
|
||
|
|
|
||
|
|
>>> print('Single quote strings can have \'single\' quotes if they are escaped')
|
||
|
|
"Single quote strings can have 'single' quotes if they are escaped"
|
||
|
|
>>> print("Double quote strings can have \"double\" quotes if they are escaped")
|
||
|
|
'Double quote strings can have "double" quotes if they are escaped'
|
||
|
|
>>> print("Multiline strings\ncan be created\nusing escape sequences.")
|
||
|
|
Multiline strings
|
||
|
|
can be created
|
||
|
|
using escape sequences.
|
||
|
|
>>> print("Backslashes \\ need to be escaped.")
|
||
|
|
Backslashes \ need to be escaped.
|
||
|
|
|
||
|
|
A _raw_ string can be used by prefixing the string with `r` or `R` which allows for backslashes to be included without the need to escape them -
|
||
|
|
|
||
|
|
>>> print(r"Backslashes \ don't need to be escaped in raw strings.")
|
||
|
|
Backslashes \ don't need to be escaped in raw strings.
|
||
|
|
>>> print(r"An odd number of backslashes at the end of a raw string will cause an error\")
|
||
|
|
File "<stdin>", line 1
|
||
|
|
print(r"An odd number of backslashes at the end of a raw string will cause an error\")
|
||
|
|
