Python에서 exception이 생긴 라인 숫자값을 어떻게 구할 수 있나요?

try:
    print("a" + 1)
except Exception as error_message:
    print("There was an error: " + str(error_message)) 

There was an error: can only concatenate str (not "int") to str

print("There was an error: " + str(error_message))

try:
    print("a" + 1)
except Exception as error_message and linenumber as linenumber:
    print("There was an error: " + str(error_message) + ". The line where the code failed was " + str(linenumber)

There was an error: can only concatenate str (not "int") to str. The line where the code failed was 2 

import traceback

try:
    print("a" + 1)
except Exception as e:
    print("There was an error: " + e.args[0] + ". The line where the code failed was " + str(traceback.extract_stack()[-1][1]))
