What You Need to Know About Mutability in Lists and Tuples

When you're learning about lists and tuples in programming, it's important to get what mutability means.

1. What is Mutability?

   • Mutable: This means you can change it after you create it.
   • Immutable: This means you cannot change it once it's created.

2. Lists:

   • Think of a list as your shopping list. You can add items, take them away, or change their order whenever you want.
   • For example in code:

     shopping_list = ["milk", "eggs", "bread"]
     shopping_list.append("butter")  # Mutable: Now the list has "butter" too.
     

3. Tuples:

   • Imagine a tuple like a team set for a competition. Once you choose the team, you cannot change it.
   • For example in code:

     prize_team = ("Alice", "Bob", "Charlie")
     # prize_team[1] = "David"  # This will cause an error! Tuples cannot be changed.
     

So, to sum it up:
Lists can be changed, but tuples are fixed!
