Hi, I understand your point. I tried by printing the standard output, but the result was the same. The output of one module is not captured in the bash script using the $(...) operation. So, I have switched to other possibilities of storing the data and accessing it from other program. Thanks for your suggestion. -- https://mail.python.org/mailman/listinfo/python-list
