KeyError when trying to get program_graph

[ppashakhanloo]

When I try to create a program graph, I encounter a KeyError. If I remove all the and and or expressions from the python file (buggy.py) the error does not occur.

This is how I use the library:

graph = program_graph.get_program_graph(code)
program_graph_graphviz.render(graph, path='source.png')

where code is simply the code in the attached file buggy.py.txt.

I have also attached the log file log.txt.

buggy.py.txt

log.txt

More information:
python 3.9.5

Thanks for opening the issue! The introduction of unparser_patch in #15 should resolve this. This will be included by default in the next release.

Hi. Is this release still in progress? I'm waiting on it for a project I'm working on. Thanks.
