Recursion in Python
Recursion is an approach to solve a problem which involves a function calling itself either directly or indirectly. Such a function is known as a recursive function. Every recursive method must have a base case which would stop calling the function again and again indefinitely, because the function stack has a limit, which is platform dependent. A Python program to print a string backwards using a recursive function. def reverse(s, n): if n > 0: print(s[n], end = '') reverse(s, n - 1) elif n == 0: print(s[0]) s = input('Enter the string: ') reverse(s, len(s) - 1) A Python program to calculate a b using a recursive function. def power(a, b): if b == 0: return 1 else: return a * power(a, b - 1) a = int(input('a = ')) b = int(input('b = ')) p = power(a, b) print('a to the power b: ' + str(p)...
