When cheking the results for my code, it fails in this test:
Fail:isallupper("45 DIG ee 5 ITS1 23")
But I don't understand why. The exercise said: "Check if a given string has all symbols in upper case. If the string is empty or doesn't have any letter in it - function should return True."
The test string contains the letters "ee" in lower case, so the right result is False, right?
Can anyone help me to understand?
