Random module, coin flipping

[perfringo]

This is homework and following may not apply.

To simulate coin flipping one can just:

>>> random.choices(['heads', 'tails'], k=5)
['tails', 'tails', 'heads', 'tails', 'tails']

To verify that it its evenly distributed:

>>> random.choices(['heads', 'tails'], k=1000).count('heads')        
501

One can add weights or cumulative weights ('biased coin'):

>>> random.choices(['heads', 'tails'], cum_weights=[0.70, 1.00], k=1000).count('heads')                                               
703

Result can be printed out using unpacking and sep:

>>> print(*random.choices(['heads', 'tails'], k=5), sep='\n') 
tails
heads
heads
tails
heads
