Agreed created the solution and then came across that the test cases aren't even working

That shouldn't be the case since there's no break statement in the for loop. I tried my code with the 3rd test case and it passes the test.

cuz "C" appears twice (once in camel, and another in case) so ur code substitutes it twice (replace will replace all occurrences, read https://www.w3schools.com/python/ref_string_replace.asp . hope this helps !

The test is failing on the 3rd test case

I just solved this kata in Python to see what's going on - I wrote everything myself, no imports, and it works fine.

However there are 1-2 tests which are a bit "unexpected" for a 7 kyu: it's not mentioned in the Description, but you need to handle cases where input is not a string.

To troubleshoot and understand what I'm saying here, you can print the input that the tests are using: to do this, type:

def check_coupon(entered_code, correct_code, current_date, expiration_date):
  print(entered_code, correct_code)
  print(current_date, expiration_date)
  # rest of your code here bla bla

then in console you'll be able to see which inputs you are failing on.

No example, no proof... Are you aware this is a pointless message?

I got the same test failing on python where every other test was passing. Must be a incorrectly written test case.

The test cases aren't working properly on this kata for python
