Fixed. Remember to hit RESET to see the updated code of example tests.

lol, old school is the best school

I agree with you, however, this is a beginner-level exercise, so I believe that understanding the necessity of using a Map/Dictionary is part of the exercise. Just my perspective

fixed

Minor issue: for Python's initial solution (the generated code when you first start solving), you missed a colon after 'def gordon(a)' (should be 'def gordon(a):')

no answer from OP

what does "is missing the function name" mean, could you be more precise ? is this about the sample tests or the full tests ?

One of the test cases in the test is missing the function name and therefore always returns false because the argument list and the result list are different

Thanks for the comment. Much appreciated!

There are some kata similar to what you suggest. Check out these:

"Check and Mate?"

"Is the King in check ?"

"One line task: Is the King in check ?"

"Explain the Algebraic Chess Notation"

"Find the Final Position"

Enjoy!

Hi, very nice kata, love it :)
Please please please make a harder version (either normal chess or atomic chess or even both) (suggestions to make it harder below)\

1. Instead of f3xe5 the input is a proper chess notation e.g. Nxe5 - this will allow move disambiguation (and of course double disambiguation!!!!)
2. Allow pawn promotion, castling and en passant
3. Verify whether a move is legal (especially for castling - cannot castle out of check, into check, or through check)
4. Require the solution to output whether either side is in check or in checkmate

The random tests don't work (at least in Python), Anything works (def calc_type(a, b, res): pass - passes all 100 of the random tests)

from string import ascii_lowercase will give you a variable (type string) called ascii_lowercase which equals 'abcdef...wxyz' (ascii_uppercase works the same way)

Decent data searching exercise.
