#n natural number s
def func(q):
    if q>0:
       return func(q-1)
       return q
    elif q==0:
       return 0

print(func(5))

So I understood a lot of recursion now I want to print natural no's outside the function...help me trace the code y o/p is 0?

What do you think it is doing line by line?
which lines don't you understand what it is doing?

You will have to explain what you want to accomplish. What I see is a function that returns "0" in a very inefficient way. And for negative input it returns "None". I can also see line 5 will never be reached.
What do you want the function to do? And why should it be recursive?
