Yes, it is.

some of the random tests have the same letter twice and yet it is supposed to be true?

Python, likely others: missing testcase for 'abcdefghijklmnopqrstuvwxyz', which is to say exactly the required characters but no additional characters. Solutions such as this one have an off-by-one bug in this case

it uses the letters A-Z at least once (case is irrelevant)

Do you know what the last part means? Also, the logic in your code is wrong. Print both parts of what you're trying to compare.
