trouble with using python dictionaries


Post reply

Has anyone run into trouble using python dictionaries and having duplicate entries?
kadamat, dicts can only have one value associated with any given key (but that value can be a list, if you so wish)
Yes, that is how it is supposed to work But how are the keys compared?
kadamat, by hash and by ==.
Like of the key is a string, how to I make sure it is checking by value Hmm, okay then I have a problem here I read in a file of triples Compose a key using the first two items and insert it into a dictionary using the third as the value
kadamat, are you printing the repr() of the keys?
No, just the key itself as returned from the k,v iter_items
kadamat, are you sure the dupes are actually dupes? Can you give an example of two keys, as printed, that you think are dupes?

kadamat, are you assembling a string out of two strings and using that as key? I suggest using a tuple of the two strings, instead. or, if you are doing that, use repr(key) instead of whatever you're using now to make them into something printable.
Hmm, okay, why should that make a difference though Okay ...
kadamat, well, for one, I can't see whitespace in that paste :)
There is a tab in the middle, but only one
Key = "\t".join((record[0],record[1]))
kadamat, regardless of how you store the key, print repr(key) instead of the key directly.
Thanks :-)
