What are mutable variables in programming?

What are mutable variables in programming?

Mutable variables are variables whose values can be changed after they are created. For example, in Python, a list is mutable.

Can you give me an example of a mutable variable?

Sure! In Python, you can create a list like this: my_list = [1, 2, 3]. You can change it later by doing my_list[0] = 10, which changes the first element to 10.

What about immutable variables? How do they differ?

Immutable variables, like tuples in Python, cannot be changed after they are created. For example, my_tuple = (1, 2, 3) cannot be modified.

Why would I use mutable variables instead of immutable ones?

Mutable variables are useful when you need to change data frequently, while immutable variables provide safety and predictability in your code.
