Rather easily. I've implemented it some time ago like this:

"""
import sys

def _traceit(frame, event, arg):
    if (frame.f_globals['__name__'] == '__main__' and
        event in ['call', 'line']):

        logger.debug('+[{lineno}]: {code}'.format(
            lineno = frame.f_lineno,
            code   = inspect.getframeinfo(frame).code_context
[0].rstrip()))
    return _traceit

sys.settrace(_traceit)
"""
