Python转义序列复杂输出(Python escape sequence complex output)

当我在Python IDLE中编写以下命令时,它将为您提供带引号的输出,我想知道为什么它会提供这样的输出。

x='''''abc\'abcddd'''''

print x

这是书面代码的输出。

''abc'abcddd

When I am writing the following command in Python IDLE it will give you the output with quotes, I want to know why it is giving such output.

x='''''abc\'abcddd'''''

print x

This is output of the written code.

''abc'abcddd

最满意答案

这是由于蟒蛇三重引用的字符串:

''' '''

它将两者之间的所有内容都解释为一个角色。 所以在你的字符串中:

'''''abc\'abcddd'''''

前三个引号'打开'字符串。 比它遇到2个引号,它被解释为字符。 接下来它会遇到一个转义报价,无论如何都会打印成报价,但它仍然使用转义报价。 然后它会遇到最后5个引号中的前3个,结束三重引号字符串。 然后它遇到另外两个引号形成一个空字符串''

在地方python的空间考虑1'事物':

''' ''abc\'abcddd ''' ''

It is due to pythons triple quoted strings:

''' '''

It interprets everything in between as a character. So in your string:

'''''abc\'abcddd'''''

The first three quotes 'open' the string. Than it encounters 2 quotes, which it interprets as characters. Next it encounters an escaped quote, which would be printed as a quote anyway, but it still uses the escaped quote. It then encounters the first 3 of the last 5 quotes, ending the triple quoted string. It then encounters 2 more quotes forming an empty string ''.

A space at the places python considers 1 'thing':

''' ''abc\'abcddd ''' ''
