Now the problem is if x is empty, there is an extra space in y, namely, y = "That's your best" rather than "That's your best" . Use a raw string: >>> foo = r'baz "\"' >>> foo 'baz "\\"' Note that although it looks wrong, it's actually right. There is only one backslash in the string foo.. This happens because when you just type foo at the prompt, python displays the result of __repr__() on the string. This leads to the following (notice only one backslash and no quotes around the printed string):This can be useful when you have two regexes, where one is used alone without format, but the concatenation of both is formatted.
