Python Escape Sequences | Python转义序列 |
可以在此处找到转义序列列表
转义序列允许将特殊字符包含在字符串中。
>>> 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.
可以通过在字符串前加上r
或R
来使用_原始_字符串,这允许包含反斜杠而无需转义它们 -
>>> 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\")
