I am trying to scrape some PLC code from the ’90s for addresses and variable names and put them in a table or dictionary or anything organized.

For example, in the code listing below, I would like to have perhaps a Python dictionary like:

{'%M00023': 'AUTO SEQUNCE ENABLED', '%M04012':'AUTO. OFF P.B.',  ... }

and so on.

The code is padded with spaces.

Is there an elegant way to do this? I have hundreds of rungs of ladder to do, and doing it by hand will be error-prone.
