Learn Algorithm Design by Building a Shortest Path Algorithm - Step 3

Tell us what’s happening:

Keys must be unique within a dictionary and they can be only immutable data types. This means you cannot use a list or another dictionary as keys.

Add another key age to your dictionary and give it the integer number 2 as value.

idk what is the problem

Your code so far


# User Editable Region

copper = {'species': 'guinea pig', 'age': '2'}

# User Editable Region

At first glance I believe the issue you are having is, the instructions say:

The number 2 you are assigning to age key is a string, it’s asking for an integer (check quotation).

Hope this helps,
Good luck :+1:
