Unable to concatenate strings using + operator in python

Question

I have written the below python program.

var = '28'
express = "r'\b" + var + "\b'"
print(express)

I expected to get r'\b28\b' but I am getting r'28'.

I don't understand why. Can someone please help me with it? Besides var is supposed to be a user input so I need to know some way to print express correctly.

Which is to say, concatenation is working fine. The question is, why are you trying to generate this string? — chepner

\b is the escape sequence for backspace. If you want literal \b in your result, use a raw string to prevent the escape sequence from being processed.

var = '28'
express = r"r'\b" + var + r"\b'"
print(express)
