How to debug python CLI that takes stdin?

Question

I\'m trying to debug a Python CLI I wrote that can take its arguments from stdin. A simple test case would have the output of

echo \"test\" | python mytool.p         


        

Answer 1

When you use pdb(or any other python debugger) it acquires stdin for debug commands, that's why you get NameError: name 'test' is not defined.

For example this command will quit debugger at the begging of a runtime and you wont get this error(nor interactive debugging) for one run:

(echo cont;echo "test") | python -m pdb mytool.py
