[Python] How do you find out what's happening in a process?

import pdb
pdb.set_trace()

Generally, searching "python debugger howto" should turn up a few useful
results. ;)

If you give a CTRL-C the Python process will die with a traceback
showing the line where the process
got stuck (assuming you started it from the command-line). You can
even run the script under the debugger and give a CTRL-C after a
while, as follows:

$ python -m pdb thescript.py
(Pdb) c
<wait a bit ...>
CTRL-C
Traceback ...
...
(Pdb) <inspect the variables and continue if you like>
