Recursion and Lambda Functions in python.ppt
- 1. RECURSION AND LAMBDA FUNCTIONS VINAY AGRAWAL ASST. PROFESSOR CEA DEPT. GLA UNIVERSITY, MATHURA
- 2. Recursion
- 3. Tower of Hanoi Problem
- 6. Programs 1. WAP to find the factorial of a number provided by user using Recursion. 2. WAP to print the fibonacci Series upto n terms, where n is provided by user. 3. WAP to find the GCD (or HCF) using Recursion. 4. WAP to input a string from the user and check whether it is palindrome or not.
- 7. Lambda Functions or Anonymous Functions Those Functions which does not have any name is called Anonymous Functions. In Python, this can be achieved by using keyword lambda, that’s why it is also called Lambda Functions. They are not declared in the standard manner by using the def keyword Lambda forms can take any number of arguments but return just one value in the form of an expression. They cannot contain commands or multiple expressions.
- 8. Syntax The syntax of lambda functions contains only a single statement, which is as follows: lambda arg1 ,arg2,.....argn:expression Example: add = lambda a, b : a + b print("Value of total : ", add( 10, 20 ) )
- 9. Non-Anonymous Function Anonymous Function def square(x): return x*x n=int(input(“Enter the Number”)) print(square(n)) a=lambda x:x*x n=int(input(“Enter the Number”)) print(a(n))
- 10. Lambda Function with map() function l=list(map(int,input().split())) Similarly L1=[1,2,3,4] L2=list(map(lambda x:x*x,L1)) print(L2) Output:[1,4,9,16]
- 11. Lambda Function with filter() function L1=[1,2,3,4] L2=list(filter(lambda x:x%2==0,L1)) print(L2) Output:[2,4]
- 12. Lambda Function with reduce() function import functools L1=[1,2,3,4,5,6,7,8,9,10] L2=functools.reduce((lambda a , b : a+b), L1) print(L2) Output:55
