I have a python script over 2000 lines and it's through the below exception on the production server and I'm not able to reproduce the issue locally to debug it and I don't know where it comes from.

Exception TypeError: TypeError("argument of type 'NoneType' is not iterable",) in <bound method Popen3.__del__ of <popen2.Popen3 instance at 0x7fccba7b65f0>> ignored
Exception TypeError: TypeError("argument of type 'NoneType' is not iterable",) in <bound method Popen3.__del__ of <popen2.Popen3 instance at 0x7fccba7b62d8>> ignored
Exception TypeError: TypeError("argument of type 'NoneType' is not iterable",) in <bound method Popen3.__del__ of <popen2.Popen3 instance at 0x7fccba824ef0>> ignored
Exception TypeError: TypeError("argument of type 'NoneType' is not iterable",) in <bound method Popen3.__del__ of <popen2.Popen3 instance at 0x7fccba824f80>> ignored

Is there a way to make the interpreter print the trace for the exception as Java does? To be able to know what is throwing this exception.

The simplest way is to use traceback.print_exc() in the except block:

try:
    1[0]  # raises
except TypeError:
    traceback.print_exc()
    raise
