Question

Is it possible to write a function in python, which takes an argument a and prints the result of h+a where h is a local variable. Then it should return itself, with h increased by one.

Answer 1

Yes, you can

def f(a):
    def inner(h, a):
        print h+a
        return lambda (x): inner(h+1, x)
    return inner(1, a)

example

g = f(0) # +1
g = g(0) # +2
g = g(0) # +3

f(0) # +1
g(0) # +4
g(0) # +4

prints

1
2
3
1
4
4
