Hi, I'm having trouble with Is An Anagram.

I would like to think I have the correct code but it is giving me fails on the test.

It returns False in pycharm when using Mary and Army but here it gives me a fail. It should return False according to testcases and it does in PyCharm but here it gives me a fail. What am I missing?

My code:
def is_anagram(str1, str2):

len1 = len(str1)
len2 = len(str2)

if len1 == len2:
if sorted(str1) == sorted(str2):
return str1 == str2
else:
return str1 == str2

is_anagram("Mary", "Army")
