This should tell you why you run into your error:

>>> message = "This is a message."
>>> m_list = message.split()
>>> m_list
['This', 'is', 'a', 'message.']
>>> y = random.choice(m_list)
>>> y
'message.'
>>> m_list.remove(y)
>>> m_list
['This', 'is', 'a']
>>> y
'message.'

You should probably move your y = random.choice() into the while loop.

A simpler way than to remove items from a list is to use random.sample:
>>> message = "This is a message."
>>> m_list = message.split()
>>> random.sample(m_list, len(m_list))
['is', 'This', 'a', 'message.']
