[Tutor] while loops

[Jay Loden]

> coin = random.randrange(2)

That's the problem there...you've got coin assigned outside the while loop, so 
it is assigned 0 or 1 once, before the loop, and then you're running 100 
checks on the same value. 

If you move 
> coin = random.randrange(2)

to inside the while loop before the if statement, you'll get the result you 
want.
