How to return error line in a given file path for python?

I want File1.py to return the error line in File2.py

File1.py:

def find_errors(file_path_of_File2):
    print(f'the error is on line {}')

the error is on line 2

File2.py:

print('this is line 1')
print(5/0)

ZeroDivisionError: integer division or modulo by zero

Is this possible?

You can do it a little bit ugly with the traceback module.

File1.py

print('this is line 1')
print(5/0)

File2.py

import sys
import traceback
try:
    import test
except Exception as e:
    (exc_type, exc_value, exc_traceback) = sys.exc_info()
    trace_back = [traceback.extract_tb(sys.exc_info()[2])[-1]][0]
    print("Exception {} is on line {}".format(exc_type, trace_back[1]))

output

this is line 1
Exception <type 'exceptions.ZeroDivisionError'> is on line 2

In this case, you will catch all exceptions raised during importing your file, then you will take the last one from the trace_back.
