In our last session, we learned how to access individual items in a list using their index, like planets[1] to get "Venus".
What if we made a mistake or want to update an item in the list?
Engagement Message
Do you think we can change it?
Yes, you can! Lists are mutable, meaning their contents can be changed after they are created.
You can replace an item at a specific index with a new value using the assignment operator =.
Engagement Message
How is this similar to assigning a value to a variable?
The syntax is: list_name[index] = new_value.
If we have planets = ["Mercury", "Venus", "Earth"], we can change "Venus" to "Mars" like this: planets[1] = "Mars".
Engagement Message
What index would you use to change "Mercury"?
After running planets[1] = "Mars", the planets list would now look like this: ["Mercury", "Mars", "Earth"].
The original value at that index ("Venus") is replaced by the new one ("Mars").

What would planets[1] give you this change?
