Question

Write a function EOReplace() in Python, which accepts a list L of numbers. Thereafter, it increments all even numbers by 1 and decrements all odd numbers by 1.

Example:

If Sample Input data of the list is:

L = [10, 20, 30, 40, 35, 55]

Answer 1

def EOReplace():
L=eval(input("Enter list of numbers :"))
print("Original list :",L)
for a in range(len(L)):
          if L[a]%2==0:
             L[a]+=1
          elif L[a]%2!=0:
             L[a]-=1
        print("Modified list :",L)
