As I am constantly searching for informations on the different parts (i.e. components on the PCB), i have scripted www.digikey.com (the HTML form is quite stable) in python in order to automatize the search on the website.
The script can be found here : digikey.py
This script can be used like : python digikey.py BC847BVNDITR-ND (BC847BVNDITR-ND is a part reference on the digikey website).
I am looking for similar that can be used/optimized for the other e-shop such as Farnell, Mouser, Radiospares in order to have a common script tool able to search all these e-shops in one and give a report on the availability for parts in a db run daily or weekly.
