Python dict.get() raises KeyError

Question

I am getting lost here, Python 2.7, I have a dictionary mt, and I use the get() method, which by documentation says:

g

Answer 1

So I nailed the problem down. Before this code was put in place there was this one

File "/home/ubuntu/subscription-workers/commands/dr/rebilling.py", line 48, in rebill
    if mt['is_rebill'] == 1:
KeyError: 'is_rebill'

The problem was that there were .pyc files from the older version, but the stack trace was loading the actual code. After running

find . -name "*.pyc" -exec rm -rf {} \;

and reloading the app everything was fine and without problems.
