I have a function like this
def try_strip(s): try: return s.strip() except Exception as e: print(e) # (I've tried inspect, traceback, logging, sys) and if I call it somewhere like this
try_strip('could be a string or not') then the exception line number would be the one in which the try_strip is defined. Is there a way to get info about where was it called? Thank you in advance.
The Traceback module which is included with Python provides this functionality. According to its documentation it:
provides a standard interface to extract, format and print stack traces of Python programs. It exactly mimics the behaviour of the Python interpreter when it prints a stack trace.
The function traceback.format_stack() will return the stack trace information you need as a list of strings while the function traceback.print_stack() will print the stack trace information to the console. Below I have included some code which shows how you might use this in the example you provided:
import traceback def try_strip(s): try: return s.strip() except Exception as e: traceback.print_stack() stack_trace_info = traceback.format_stack() # Code that write stack_trace_info to a log could go here try_strip(5) # This will cause an error at runtime For additional info on the Traceback module, please see https://docs.python.org/3/library/traceback.html .
