Answer 1

def raise_to_power(base_num, pow_num):
result = 1
#this loop runs pow_num=2 times, and base_num=3
for index in range(pow_num):
result = result * base_num

#iteration 1 : result = 1*3 = 3
#iteration 2 : result = 3*3 = 9

return result #returns 9

print(raise_to_power(3,2)) #calling function with 3,2 arguments

edit:
if you don't know, :
yes, it is user implemented power of function.
equal to using simply print( 3**2 )
** is power of operator in python..

Answer 2

It is a complicated way of doing this:

print ( 3 ** 2 )
print ( 2 ** 4 )
print ( 5 ** 5 )
