use of backslah

Question

The preparation kit just had this question
Complete the code to create a string containing a double quote.
>>> "--" ans: \"
why wouldn't the answer be just ( " ) and why it needs a back slash

Answer 1

(") is a double quote within parentheses. It's not a string, let alone a string containing a double quote. In fact, it doesn't quite mean anything in Python, hence it can't possibly be the answer.

Certain characters are illegal in a string. A string containing a double quote would look like

"""

if unescaped. To the interpreter, this looks like a triple quote. Instead, you escape the double quote using a backslash.

"\""

so that the interpreter understands that the double quote is part of the string instead of a closing quote.
