Short version: Try adding a "sys.stdout.flush()" after each of your print
statements in your python script.
Longer version: when you run that program in a terminal, the output is a
TTY and the standard output is flushed after every line. When you run it
as a subprocess, the standard output is
Thx! sys.stdout.flush() works but in real use cases I cannot add
sys.stdout.flush() to every python print.
Can I do anything in the racket side to solve the problem? Making the
interactive window behave like terminal perhaps?
