Hpoe it will help you.

read the docstrings below the code to know what was wrong.

Answer 2

you are iteratîng the string hexstr from left to right, but you are supposed to iterate from right to left ^^

to easily fix you code, reverse the hexstr at start of the function ;)

anyway, your code could be improved a lot (turn upper the string at start, use ascii code to compute hex digits values rather than iterating over a tuple...), and python provide already conversion function utils ;P

Answer 3

Thank you so much...I'm not really understand about List Slicing.
