Inspired by the complexity of Neo.

When browsing/inspecting an object, you want to collect all methods and attributes that match the key.

Browsing the documentation of neo.io.BlackrockIO and looking for the ways of extracting Epochs, you found read_epoch() method. But calling this method raises AssertionError. You need to go deeper.

1. Run pip install pinspect neo
2. Download BlackRock sampledata.zip

wget http://www.blackrockmicro.com/wp-content/software/sampledata.zip
unzip sampledata.zip

3. In python,

from neo.io import BlackrockIO
from pinspect import find

session = BlackrockIO('sampleData')
graph = find(session, 'epoch', verbose=True)

Output:

BlackrockIO.rescale_epoch_duration() -> 'TypeError'
BlackrockIO.read_epoch() -> 'AssertionError'
BlackrockIO._rescale_epoch_duration() -> 'TypeError'
BlackrockIO.read()[0].segments[0].epochs -> 'list of size 0'
BlackrockIO.read()[0].segments[0].events[0].to_epoch() -> 'Epoch'

The last two lines are candidates to explore manually.

You can pass visualize=True and enjoy the beautiful networkx with pyvis interactive graph rendering. Hover over the nodes (objects) and edges (methods and attributes) to explore the graph in details and inspect how a particular object has been generated.

Below is the full unfiltered graph of neo.BlackRockIO of all possible method and attribute calls. Can you find the green dot?

1. Python 3.6+
2. requirements.txt

Another package to inspect python variables is objbrowser.
