This implementation is a copycat of Scott Boland's Java implementation, but re-written into Python. It's not a direct translation - but based on his code. I did not carry over the GUI, as this version can more usefully be run from command line, or imported for use by other Python scripts.
I also tried to make the code more pythonic.
There are no particular installation instructions, just clone and run, e.g.
$ git clone https://github.com/jalanb/co.py.cat.git $ cd co.py.cat/copycat $ python main.py abc abd ijk
The script takes three arguments. The first two are a pair of triplets with some change, for example "abc" and "abd". The third is a triplet which the script should try to change analogously
For example the following invocation will probably display "ijl"
$ python main.py abc abd ijk
