 You might think that this would work:

 `string` didn't change. Why is that so?

 That's because strings in Python are _immutable_. You can't change them, you can only pass around existing strings or create new ones.
 
 ```python
-string = "abcd"
-string = string.upper()
+>>> string = "abcd"
+>>> string = string.upper()
+>>> string
+'ABCD'
 ```
 
 `string.upper()` creates and returns a new string which is like the old one, but with all the letters turned to upper case.

 Mutable data types like `list`, on the other hand, can be changed in-place:
 ```python
-my_list = [1, 2, 3]
-my_list.append(4)
-print(my_list) # [1, 2, 3, 4]
+>>> my_list = [1, 2, 3]
+>>> my_list.append(4)
+>>> my_list
+[1, 2, 3, 4]
 ```
 
 Other examples of mutable data types in Python are `dict` and `set`.
