traceback module in Python

So, i thought why not write an article on how to get the Python interpreter like error messages.

I read about it firstly on StackOverflow and from the Python documentations.
So, here we go on a basic tour of exception handling with traceback.

imports

We need to import the python sys module and traceback module.

import traceback
import sys

Then we will use the sys modules sys.exc_info() method to extract the exception_type,exception and traceback.
And after gettting all these values we will print these using the traceback modules traceback.print_tb() method:

import traceback
import sys

try:
    a = 8/0
except:
    ex_type, ex, tb = system.exc_info()    
    print(traceback.print_tb(tb))

Outputs:

File "<stdin>", line 2, in <module>

That is a basic use case of traceback and if you wanna learn further about it you might want to read some stackoverflow answerws and the official python documentation:
