How do I simulate flip of biased coin in python?

Question

In unbiased coin flip H or T occurs 50% of times.

But I want to simulate coin which gives H with probability 'p' and T with probability '(1-p)'.

something like this:

def flip(p):
   '''this function return H with probability p'''
   # do something
   return result

>> [flip(0.8) for i in xrange(10)]
[H,H,T,H,H,H,T,H,H,H]

Answer 1

• Import a random number between 0 - 1 (you can use randrange function)

• If the number is above (1-p), return tails.

• Else, return heads
