Changing List Items in Python

You can change list items in Python using direct index assignment, slices, or loops. Here are various methods:

1. Change item using index

names = ["Raj", "Simran", "Aman"]
names[1] = "Pooja"
print(names)

Output:

["Raj", "Pooja", "Aman"]

2. Change multiple items using slice

names = ["Raj", "Simran", "Aman"]
names[0:2] = ["Karan", "Arjun"]
print(names)

Output:

["Karan", "Arjun", "Aman"]

3. Replace last item using negative index

names = ["Raj", "Simran", "Aman"]
names[-1] = "Preeti"
print(names)

Output:

["Raj", "Simran", "Preeti"]

4. Change all items using loop

names = ["Raj", "Simran", "Aman"]
for i in range(len(names)):
    names[i] = names[i].upper()
print(names)

Output:

["RAJ", "SIMRAN", "AMAN"]

5. Update by index using user input

names = ["Raj", "Simran", "Aman"]
index = 1
new_name = "Deepika"
names[index] = new_name
print(names)

Output:

["Raj", "Deepika", "Aman"]
