Python doctest says failed but returns correct value

Question

I was preforming some doctests in PyCharm and I ran the test in the python console. It passes one and fails the other, but the failure shows the value returned being the correct value. Does anyone know what I might be missing or if this is a known error in PyCharm, etc?

Here is the code

def friend_date(a, b):
    """
    Returns True if they have any hobbies in common, False is not.

    >>> elmo = ('Elmo', 5, ['hugging', 'being nice'])
    >>> sauron = ('Sauron', 5000, ['killing hobbits', 'chess'])
    >>> gandalf = ('Gandalf', 10000, ['waving wands', 'chess'])

    >>> friend_date(elmo, sauron)
    False

    >>> friend_date(sauron, gandalf)
    True 
    """
    return bool(set(a[2]) & set(b[2]))

Didn't realize spaces mattered like that in python, only thought it mattered to indent properly. Thank you so much @user2357112supportsMonica — brent-franklin

Indeed as @user2357112 pointed out you have space in the expected output for your second test case. I tested with this code and it worked:

def friend_date(a, b):
    """
    Returns True if they have any hobbies in common, False is not.

    >>> elmo = ('Elmo', 5, ['hugging', 'being nice'])
    >>> sauron = ('Sauron', 5000, ['killing hobbits', 'chess'])
    >>> gandalf = ('Gandalf', 10000, ['waving wands', 'chess'])

    >>> friend_date(elmo, sauron)
    False

    >>> friend_date(sauron, gandalf)
    True
    """
    return bool(set(a[2]) & set(b[2]))
