Kata

Please use new python test framework.

The part y is a vowel is way below the descriptions so it's hard to see.

Can't you just put it along the remove all vowels part?

According to my knowledge, "y" is not an English vowel. However, I am not a native speaker.

Minor improvements suggested:

• do not use the reserved word "string" as the input variable
• mention in the description that "Y" is considered a vowel (usually it's only AEIOU)
• consider adding random tests

Otherwise a nice and fun kata!
