I'm getting a KeyError for an out of dictionary key, even though I know the key IS in fact in the dictionary. Any ideas as to what might be causing this?
print G.keys()
returns the following:
['24', '25', '20', '21', '22', '23', '1', '3', '2', '5', '4', '7', '6', '9', '8', '11', '10', '13', '12', '15', '14', '17', '16', '19', '18']
but when I try to access a value in the dictionary on the next line of code...
for w in G[v]: #note that in this example, v = 17
I get the following error message:
KeyError: 17
Any help, tips, or advice are all appreciated. Thanks.
