Question

Given two strings, return True if either of the strings appears at the very end of the other string, ignoring upper/lower case differences (in other words, the computation should not be "case sensitive").

Examples / Tests:

>>> end_other('Hiabc', 'abc') 
True 
>>> end_other('AbC', 'HiaBc') 
True 
>>> end_other('abc', 'abXabc') 
True

My Code:

def end_other(s1, s2):
    
    s1 = s1.upper()
    s2 = s2.upper()
    
    if s1[2:6] == s2:
        return True
    elif s2[2:6] == s1:
        return True
    elif s2 == s1:
        return True    
    else:
        return False

What I expect is wrong.

Any reason you can’t use the built-in functions?

def end_other(s1, s2):
    s1 = s1.upper()
    s2 = s2.upper()
    return s1.endswith(s2) or s2.endswith(s1)

Your code with the arbitrary slices doesn’t make a lot of sense.
