单引号、双引号作为 Python 输入值

Question

I used the following command and I got different values stored in the variable each time.

name=input('enter your name:')
enter your name:'' (two single quotes)
name
"''" (this is how it is displayed after I type 'Name' and press 'Enter')

name=input('enter your name:')
enter your name:"" (two double quotes)
name
'""' (this is how it is displayed after I type 'Name' and press 'Enter')

name=input('enter your name:')
enter your name:"'"' (double, single, double, single)
name
'"\'"\'' (this is how it is displayed after I type 'Name' and press 'Enter')

name=input('enter your name:')
enter your name:'"'" (single, double, single, double)
name
'\'"\'"' (this is how it is displayed after I type 'Name' and press 'Enter')

What does the \\ indicate in the variable 'name' and why is it at all there?

Answer 1

It is there to escape a single quote in a single quotes strings. This "escaping" allows you to use single and/or double quotes in a string. You can work around this by using a double quote in a string quoted with single quotes are vice versa. But this does not work anymore if you have a string with single quotes and double quotes. So you have use escaping now.

The Python console just wants you to see the variable, not the contents of the variable that's why you see escaping. You can also just display the string with print and you won't see the escaping, because you now just see the string as is.

So, just use print(name)
