 From https://docs.python.org/3/whatsnew/3.1.html#other-language-changes

"The string.maketrans() function is deprecated and is replaced by new 
static methods, bytes.maketrans() and bytearray.maketrans(). This change 
solves the confusion around which types were supported by the string 
module. Now, str, bytes, and bytearray each have their own maketrans and 
translate methods with intermediate translation tables of the 
appropriate type."
