Use pdb.set_trace() in a script that reads stdin via a pipe

Question

I have a python script that reads stdin via a pipe, and I cannot seem to use it with pdb.set_trace().

my_script.py:

#!/usr/bin/env python
import sy         


        

Answer 1

The thing is: cat will not stop sending data because your script is currently debugging. And when you going to trace, then stdin is still filled by cat + your keyboard. You need to choose one of them.

You can read the whole stdin, and then, set_trace() will be not filled by stdin:

sys.stdin.read()
pdb.set_trace()
