### PUT YOUR WORK FOR PROBLEM 4 BELOW. ###

### IMPORTANT NOTES:
###  - One of your functions must use a for loop, and the other function 
###    must use a while loop. You should decide which type of loop is 
###    more appropriate for each function.
###
###  - Each function must call throw_dart() from inside its loop. 
###    For full credit, each function must have *EXACTLY ONE* line of
###    code that calls throw_dart(). If a given function has fewer 
###    or more than one line of code that calls throw_dart(), you 
###    will lose points. 
###
###    In addition, your functions must *NOT* make their own calls 
###    to random.uniform(), and you will lose points if they do so.
