Thanks, ill look into it. And thanks for the heads up of the spoiler tag.

• Click the spoiler tag when posting code. (I have added the tag).
• Use proper markdown when posting code. I was able to know your Python indentation here only because the code is simple. Otherwise I would not want to guess at it.
• placing get_middle("cJq") with your code runs the code, but doesn't test it. You can create sample tests by using expected results from random tests: Test.assert_equals(get_middle("cJq"), "J")
• you need to look at the error messages:

Testing for jelqimTJlNhTk
It should work for random inputs too: 'mTJ' should equal 'T'

This shows that you are returning three characters instead of one. So you have that to fix in your code now.

What do you mean by

testing those tests

Bluntly, your end is not correctly validating your code. You have to go with the Codewars results.

I was able to pass the test

Sounds like you only passed the sample tests part. When you press SUBMIT, there are fixed and random tests you have to pass.
