Examples:

Hello, World! - Python (52):

print "Hello, World!"

Factorial - Python (53):

This example uses recursive factorial definition. 

def factorial(n):
    if n == 0:
        return 1
    else:
        return n * factorial(n - 1)

for n in range(16 + 1):
    print "%d! = %d" % (n, factorial(n))

Fibonacci numbers - Python (61):

This example uses recursive definition of Fibonacci numbers. 

#! /usr/bin/env python
def fibonacci(n):
    if n < 3:
        return 1
    else:
        return fibonacci(n - 1) + fibonacci(n - 2)

for n in range(1, 16 + 1):
    print "%i," % fibonacci(n) ,
print "..."

Factorial - Python (377):

This example uses iterative method of calculating factorials. 

def factorial(n):
    if n == 0:
        return 1
    
    f = 1
    for i in range(1, n + 1):
        f *= i
    return f

for n in range(16 + 1):
    print "%d! = %d" % (n, factorial(n))
