Thanks for the tip :)

Functionally, there is no difference. However, using maketrans in the encode and decode methods will perform the computation every time something is encoded or decoded (or perform an additional check on whether it has been), whereas using it in the instantiation will perform the computation only during instantiation.

So performing the calculation during instantiation is better performance-wise if you're doing a lot of encoding and decoding.

Is there a difference between using "maketrans" in the "encode" and "decode" methods or in the instantiation?

You guys forfeit algorithm creation.
