 - Do you just need an ordered sequence of items? Go for a list.
 - Do you need to associate values with keys, so you can look them up efficiently (by key) later on? Use a dictionary.
 
-Dictionaries, like lists, are *mutable*, meaning that they can be changed after they are created. You can add new key–value pairs to a dictionary after it is created, like this:
+Like lists, using the `len()` function on the dictionaries returns the number of key–value pairs in the dictionary. Go ahead and type in this command:
 
 {% filename %}command-line{% endfilename %}
 ```python
->>> participant['favorite_language'] = 'Python'
+>>> len(participant)
+3
 ```
