trying to input a variable using random.choice

[perfringo]

Using 'list' as a name is not great idea and should be avoided (unless one likes nasty surprises down the road):

>>> spam = list()
>>> spam
[]
>>> list('abc')
['a', 'b', 'c']
>>> list = []
>>> spam = list()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'list' object is not callable
>>> list('abc')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'list' object is not callable
