By using Python3.6:

1.Write a function called has_duplicates() that takes a list and returns True if any two items in the list are equal. So for example, has_duplicates([1,7,3,7,4]) should return True and has_duplicates(["one","ONE","One"]) should return False.

2.Write a function called remove_duplicates() that takes a list and removes any extra occurrences of values that appear multiple times in the list. I don't care what order the values in the new list have. So for example, if you have the definition L1 = ["a", "b", "a", "c", "c", "c"] and you run remove_duplicates(L1), then depending on how you implement this function, L1 could end up as ["a", "b", "c"], or as ["b", "a", "c"]. Either is acceptable.
