Changes:
- Update shebang directive to use python3 explicitly.
- remove preexec_fn feature which is deprecated in higher
python version 3.8 and above.
- bufsize fix, from documentation bufsize 1 means line buffered
(only usable if universal_newlines=True i.e., in a text mode)
refer: https://docs.python.org/3/library/subprocess.html
- Fix SyntaxWarning: "is" with "=="
