I am trying to do a challenge, and the memory address of the function I am trying to locate is in 0x400abd and when I use "xbdx0ax40" in python for a buffer overflow the 0x0a gets interpreted as 0x00 which makes the address 0x4000bd.

I tried to find out what it was and I know that it is because 0x0a is n but I don’t know how to fix it. I have been looking all over but all the problems are that x0a is not interpreted as n but I want the opposite. Sorry if the answer has already been answered I just couldn’t find it and I have been looking for hours.
