  2. Find the index position of "banana" and "Cherry".
  3. Replace "banana" with "Blackcurrant".
  4. Replace "Cherry" with "Watermelon".
  5. Print the updated list.

Source Code (Beginner Friendly)

# Python program to replace banana and Cherry in the list

# Creating the list
Fruit = ["apple", "banana", "Cherry", "Mango", "Kiwi", "dragon"]

# Replacing the values
Fruit[1] = "Blackcurrant"
Fruit[2] = "Watermelon"

# Printing the updated list
print(Fruit)

['apple', 'Blackcurrant', 'Watermelon', 'Mango', 'Kiwi', 'dragon']
