Learn Algorithm Design by Building a Shortest Path Algorithm - Step 15

Tell us what’s happening:

I’m struggling with tuples for some odd reason. The message I get is:

Your dictionary should have 4 keys called A , B, C, and D.
my_graph[“A”] should be a list of tuples.
my_graph[“A”] should be a list of tuples where the first item in the tuple is the connected node and the second item is the distance.

As always, thank you for your help.

Your code so far


/* User Editable Region */

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

/* User Editable Region */

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

you are missing the comma at the end of line, making it a syntax error and none of the tests pass
