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 .
