Here is the shell code. It runs out of the box.

from rt import close_enough, run_test, run_test_float
def power_rec(base, exp):
    """prec:  base is a number, exp is an integer
    postc: retuerns base**exp using a recursive version of the 
    divide and conquer power algorithm"""  
    return 1
def power_iter(x, b):
    """prec:se is a number, exp is an integer
    postc: returns base**exp using an itearative version of the 
    divide and conquer power algorithm"""  
    return 1
def main():
    ##run tests here
    run_test(power_rec, 1024, [2, 10])
main()
