Ohh thats exactly it!
I forgot to remove my print() tests.
Are you printing too much to the console?
I'm doing this kata in Python. I've managed to work out how to sort the list by string length. I pass all inital 'tests', and then I pass all 'attempts', including all 3 random tests.
Here are the results copied: Time: 906ms Passed: 8 Failed: 0 Exit Code: 137
However, I get an error at then end that stats this:
Max Buffer Size Reached (1.5 MiB)"
Any ideas what I'm doing wrong?
