if result == 1:
print("Input string is a palindrome.")

else:
print("Input string is not a palindrome.")
Program 13: Write a program that takes a user-provided string as input and then generates a new string where the
case (uppercase to lowercase and vice versa) of each character in the original input is reversed, and finally, print the
resulting string.

Ans. def swapCase(string):
'''
Objective : To convert the case of the characters of the string

Input Parameter : string
Return Value : newString – string
'''
newString = ''
for char in string:

if char.isalpha():
if char.islower():
newString += char.upper()
else:
newString += char.lower()

else:
newString += char
return newString

string = input("Enter a string: ")

newString = swapCase(string)
print("The string after reversing the Case is : ", newString)
Program 14: Write a program that takes a user-provided list as input and then generates a new list comprising swapped
values at odd indices with those at even indices.

Ans. def swappOddEvenIndex(myList):

'''
Objective : To swap values at odd indices with those at even indices
Input Parameter : myList - list
Return Value : myList - list with swapped values
'''
for x in range(0,len(myList)-1,2):

myList[x], myList[x+1] = myList[x+1],myList[x]
return myList

myList = []
