Let's say hypothetically you wanted the most bang for your buck when shopping for capacitors. You could sort DigiKey parametricly by cost or capacitance, but why not both? Through an text cleaner, parameters could be divided, multiplied, squared, etc. to sort by a complex parameter. I could and want to help with this, but before I start, I want to know if you have any objections or concerns. I'm not sure how network and server intensive this may end up being.

Hi,
It is a great tool. I have no issues installing it on windows 7 machine and some small problems adapting it to a Linux machine.
I tried to insert in the database some of my parts from the last 10 years to see how it works (almost 1000 parts) and I had 2 main problems. One of them is that DK changed some old part numbers and they don't exist anymore or are under different name that are not linked to the old one - nothing can be done about that. The second problem is that the part number exists but it is not properly transferred as request. It is because in your script digikey.py you selected to use html.escape(part_id) but it is not the right one for this purpose. I changed that to:
from urllib.parse import quote
...
url = ... + quote(part_id,safe='');
This will make possible to search for part numbers like 24FC64F-I/P-ND, DS1307+T&RCT-ND, etc.

I also have experimented with adding a function to search for the legacy 1D barcodes. The input from the user is checked first if it looks like 22 digits legacy 1D barcode (like 1642795000000250526056) and it converts it to a Digikey part number before trying to search for product information. This makes the input to the script much easier when you have the parts in anti-static envelopes with barcode labels and by using the barcode reader to enter them in milliseconds to the script. That works just fine but the newer 2D barcodes produce much more data (including the Digikey part number inside) and it needs more time to make it working.
