Not sure what the issue is.

Your code so far


/* User Editable Region */

my_graph = {
    'A': [('B', 3), ('D', 1)],
    'B': ['A', 'C'],
    'C': ['B', 'D'], 
    'D': ['A', 'C']
}

/* User Editable Region */

    'B': ['A', 'C'],
    'C': ['B', 'D'],
    'D': ['A', 'C']
}

Please talk to us in your own words about what in the instructions or error message has you stuck or confused.

this is quite a syntax error, you can’t have those key: property pairs floating around

@JeremyLT @ilenia

My code is as follows.


my_graph = {
    'A': [('B', 3), ('D', 1)],
    'B': ['A', 'C'],
    'C': ['B', 'D'], 
    'D': ['A', 'C']
}

The error I receive is that my dictionary “should have 4 keys called A , B , C , and D .”

I do have those four dictionaries. I also cleaned up the other key: properties pairs.

good job, now it passes the tests
