Re: [HTCondor-users] python bindings?

[Jason Patton <jpatton@xxxxxxxxxxx>]

Welcome to the world of the Python bindings! What you have been returned is a ClassAd object, which will act very similar to a dict (and can be easily turned into a dict) but with some different properties:

https://htcondor.readthedocs.io/en/latest/apis/python-bindings/api/classad.html#classad.ClassAd

Two properties of ClassAd objects that you should immediately be aware of is

1. The keys are case-insensitive

2. The values can contain expressions (classad.ExprTree objects) that can reference ClassAd functions ( see https://htcondor.readthedocs.io/en/latest/misc-concepts/classad-mechanism.html ) and that can reference other keys ("attributes") that may or may not be in the ClassAd object you have been returned

i'm newish to python and definitely new to the python bindings for
htcondor.  I don't understand the return values

(this is all pseudo code)

for job in schedd.xquery(projection=[]):
  print(job)

the returned values are something like

[ blah = "blah";
  blah = "blah";
  blah = "blah"; ]

what i expected was that 'job' would be a dictionary that i could then
iterate or reference into like a normal key/value hash

i looked over the docs and tutorials, but i think i'm missing
something fundamental here
