'''Question 2:
Fill in the blanks to make the is_power_of function return whether 
the number is a power of the given base. Note: base is assumed to be a positive number. 

Tip: for functions that return a boolean value, you can return the result of a comparison.

  # Base case: when number is smaller than base.
  if number < base:
    # If number is equal to 1, it's a power (base**0).
    return __

  # Recursive case: keep dividing number by base.
  return is_power_of(__, ___)

print(is_power_of(64,4)) # Should be True
