Python3.5 subprocess not writing on terminal while writing print logs in file
Below is my script which calls another script using below example and produces entire output after execution is completed while expectation is that it should produce live output as well as write in file at the same time.
from subprocess import Popen, PIPE, STDOUT with Popen("./tests.py", stdout=PIPE, stderr=STDOUT, bufsize=1, universal_newlines=True) as p, \ open('tests.log', 'ab') as file: for line in p.stdout: # b'\n'-separated lines print(line, end='') #new addition sys.stdout.buffer.write(line) file.write(line)
./My_Tests.py ALL TC 1 : PASSED TC 2 : PASSED Tatal Passed Tests : 2 Tatal Failed Tests : 0
Issue: Execution of script is not producing output line by line and printing entire output in the end while expectation is terminal logging and saving logs in file shall happen simultaniously.
