Following is an example of a recursive function tofind the factorial of an integer. Factorial of a number is the product of all the integers from 1 to that number. For example, the factorial of 6 (denoted as 6!) is1*2*3*4*5*6 = 720. Example of a recursive function deffactorial(x...
Example: Function to Add Two Numbers # function with two argumentsdefadd_numbers(num1, num2):sum = num1 + num2print("Sum: ", sum)# function call with two valuesadd_numbers(5,4) Run Code Output Sum: 9 In the above example, we have created a function namedadd_numbers()with argument...

It is standard to use a recursive function to traverse a tree. The listing in Example 7.11 demonstrates this. def traverse(t): try: t.node except AttributeError: print t, else: # Now we know that t.node is defined print '(', t.node, for child in t: traverse(child) print ')',...
Let’s write a recursive function to compute the nth Fibonacci number: Python deffibonacci_recursive(n):print("Calculating F","(",n,")",sep="",end=", ")# Base caseifn==0:return0elifn==1:return1# Recursive caseelse:returnfibonacci_recursive(n-1)+fibonacci_recursive(n-2) ...

Class decorators are less common than function decorators. You should document these well, so that your users know how to apply them. Caching Return Values Decorators can provide a nice mechanism for caching and memoization. As an example, look at a recursive definition of the Fibonacci sequence...
