Running python script on C# and getting output continuously

Question

I\'m trying to run a python script from C# and I want to get the output line by line and not at the end. I feel like I\'m missing something important, but don\'t know what.

Answer 1

change your python code to the following:

import time
import sys
for i in range(5):
    print("Hello World " + str(i))
    sys.stdout.flush()
    time.sleep(1)

or just edit your c# code and use -u switch:

var cmd = "-u C:/Users/user/Documents/script.py";

When standard output it was being redirected, the event in C# wasn't being raised when a line was written on console because there were no calls to stdout.flush;

Putting a stdout.flush() statement after each print statement made the events fire as they should and C# now captures the output as it comes.

Or you could just use -u switch.
