That utility is only compatible with Python3!

just do:

python3 install

and it’ll be available as a shell command:

% pyparts -h

when the tool will be considered stable enough, I’ll upload it to pipy:

% pip install pyparts


To use the tool you need to get an API key from Octopart for this to work. To do so, you need to create an account and connect to the Application registration page at Octopart and register an app (choose whatever name and url you want). From there you can copy the API key, e.g. ‘ab12cd45’ and use it the following way:

% pyparts -k ab12cd45 lookup 'NE555'

or store it in a config file, to avoid putting the key at each invocation of the tool, default location being ~/.config/pyparts.cfg:


or if you want to store your config file elsewhere, you can:

% pyparts -c ~/.pyparts.cfg lookup 'LM317'


if you just want to develop, you can do:

% buildout

which will download dependencies and deploy the CLI tool in bin:

% bin/pyparts

You can run regression tests using:

% bin/test
