Comment (by ncohen):
Yo,
> ok, let's follow the majority: edgelist is either a list of pairs (one
pair source-destination per line) or a list a triples source-dest-label.
Thanks.
> However, I don't understand why you treat labels as strings. I assume
that most of the time the label will be a cost or a weight or a capacity,
so int or float. You could use e.g. `eval(w)`?
I assume the same, but can I make this assumption in the code? I wanted to
have a 'float' there, but then I do not know. The problem with 'eval' is
that you "just can't" eval anything that you are given. I could take
control of your computer by sending you an "edgelist" file. Of course this
will probably never happen, but I don't like much knowing that I made this
possible `:-/`
