Answer 1

overloading is basically a methodology of something which can work accordingly what we provide to it.

def a_power_b(a,b=None):
if b==None:
return a**0
else:
return a**b
print(a_power_b(5,6))
>>>15625
print(a_power_b(5))
>>>1
here function a_power_b is taking parameter a and b
if we provide only a it will return a to the power zero i.e 1
but if we give two argumnts integer type it will display the b power of a 5**6 = 5*5*5*5*5*5
