My sentiment exactly

I just learned of Python's built in "hex" function and was originally planning to use this, but am also simultaneously working on a solution that is hard coded. Unfortunately, it's just going to appear a little messy with me having to specify conditions regarding the Hex table.

I don't think using Python's built-in hex formatting code 02X should be allowed. This is an #algorithms challenge; people should be writing the algorithm for this conversion, not using built-ins.
