Aim: To calculate the factorial of the given number using for loop. Coding: num = int(input('Enter a Number: ')) fact = for i in range( ,num+ ): fact = fact * i print("Factorial of ", num, " is ", fact) Output : Enter a Number: Factorial of is Result: Thus the Python program to calculate factorial has been done and the output is verified. PY1 (b) - Sum of Series ( b ) Write a program to sum the series / + / + / + …….
n n /n Aim To calculate the sum of the series : / + / + / + ……. n n /n Coding: n = int(input("Enter a value of n: ")) s = for i in range( ,n+ ): a= (i**i)/i s=s+a print("The sum of the series is ", s) Output : Enter a value of n: The sum of the series is 12th Computer - - PY2( a ) – Odd or Even ( a ) Write a program using functions to check whether a number is even or odd. Aim: To check whether a number is even or odd using user defined function . Coding: def oddeven(a): if (a% == ): return "Even" else: return "Odd" num = int(input("Enter a number: ")) print("The given number is ", oddeven(num)) Output : Enter a number: The given number is Odd Enter a number: The given number is Even Result: Thus the Python program to check whether a number is odd or even has been done and the output is verified.
PY2( b ) – Reverse the string ( b ) Write a program to create reverse of the given string. For example, “wel” = “lew“. (Don’t use string slice with stride operation) Aim: To create a reverse of the given string Coding: def reverse (str1): str2='' for i in str1: str2 = i + str2 return str2 word = input("\n Enter a String: ") print("\n The reverse of the given string is: ", reverse(word)) 12th Computer - - Output : Enter a String: school The reverse of the given string is: loohcs Result: Thus the Python program to reverse the string has been done and the output is verified. PY3 – Generate values and remove odd numbers
