Python code for a string program

HI!
could anyone help me out with the code for below 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"). Note: s.lower() returns the lowercase version of a string.

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

Code:

>>> import pprint
>>> pprint . pprint ( dir ( '' ) )
['__add__',
 '__class__',
 ...
 'endswith',
 ...
 'zfill']
>>>

You can either reverse the letters in the words and check the beginning or convert to lists and start at -1 comparing letters.

Code:

def end_other(x, y):
    return x[::-1][0:len(y)] == y[::-1]

case-insensitive:

Code:

def end_other(x, y):
    return (x[::-1][0:len(y)]).lower() == (y[::-1]).lower()

You don't seem to get it.

endswith is a string method.

I suppose if this is homework they might not be expected to use a function, other than lower().. maybe len(). Although, my method is a bit cheeky

Converting to lists is unnecessary as a string is already an iterable.
