Get exception description and stack trace which caused an exception, all as a string

Question

How to convert a caught Exception (its description and stack trace) into a str for external use?

try:
    method_that_can_raise_an_exception(params)
except Exception as e:
    print(complete_exception_description(e))

Answer 1

See the traceback module, specifically the format_exc() function. Here.

import traceback

try:
    raise ValueError
except ValueError:
    tb = traceback.format_exc()
else:
    tb = "No error"
finally:
    print(tb)
