This function computes whether number is even or odd.
def evenorodd():for loop iterates number from 1 to 20
for i in range(1,20):Here if condition checks whether number is divisible by 2 or not
if((i%2)==0):If the number is divisible by 2 it prints as even numbers
print i, "is a even number"if condition fails then else condition will execute
else:If number not divisible it will prints as odd numbers
print i, "is a odd number"This is function call which calls evenorodd function
