Well, you said yourself that you finish with a list of length 7.  And you
are doing this as long as your list is shorter than 8.  7 < 8 is always
true → infinite loop.

Do you know `random.shuffle()`?

In [4]: random_list = range(7)

In [5]: random.shuffle(random_list)

In [6]: random_list
Out[6]: [1, 4, 6, 2, 5, 0, 3]

Same effect but more efficient than your approach.
