New submission from DJ PJs <[email protected]>:
Keeping writing to a subprocess, and then flushing it to get the stdout works
for other interpreters, but not python's.
Simplified Example of what I mean:
from subprocess import PIPE, Popen, CREATE_NEW_CONSOLE, run
subProcess = Popen("Python", stdin=PIPE, stdout=PIPE, text=True,
universal_newlines=True)
subProcess.stdin.write('Print("HelloWorld")')
subProcess.stdin.flush()
for line in subProcess.stdout:
print(">>> " + str(line.rstrip()))
subProcess.stdout.flush()
