NEED HELP WITH THIS IN PYTHON

#Define a function, number_of_vowels, that returns the number of vowels in a string. Use it with your best function to find the name in names with the most vowels.

#See how easy it is to change the score function for different functionalities!

#Example:

#print(best(number_of_vowels, names), "has the most vowels.")

#Alexis has the most vowels.
