python使用什么符号防止转义

在 Python 中,可以使用反斜杠 (\) 来防止转义。例如,如果要在字符串中包含反斜杠,可以使用两个反斜杠来表示一个反斜杠,这样就可以防止转义了。例如:
```
>>> print("This is a backslash: \\")
This is a backslash: \
```
如果要在字符串中包含单引号或双引号,可以使用反斜杠加单引号或双引号来表示。例如:
```
>>> print('This is a string with a single quote: \'')
This is a string with a single quote: '
>>> print("This is a string with a double quote: \"")
This is a string with a double quote: "
```
在 Python 中,还有一种更简单的方法来表示字符串,即使用三个单引号或三个双引号。使用这种方法可以很方便地在字符串中包含多行文本或多个引号。例如:
```
>>> print('''This is a multi-line string with single quotes.
It can contain multiple lines of text and single quotes without the need to escape them.''')
This is a multi-line string with single quotes.
It can contain multiple lines of text and single quotes without the need to escape them.
>>> print("""This is a multi-line string with double quotes.
It can contain multiple lines of text and double quotes without the need to escape them.""")
This is a multi-line string with double quotes.
It can contain multiple lines of text and double quotes without the need to escape them.
```
