Hi,
I want to use the stdout of child process as an input of another thread, but some how I am not able to read the stdout. Using Popen I have created a child process and stdout of it I have redirected to PIPE (because I don't want that to be printed on with my main process). Now using this statement,"Line=Proc.stdout.readline()" I want to read stdout of child process and I have to do operation on that. but somehow i am not able to read from stdout of child process.
Following is the code snapshot -
Proc = Popen(["python.exe","filename.py"],stdout=PIPE)
while True:
Line = Proc.stdout.readline()
print Line
Here,
Filename.py(Child process) is continuously printing "Hello World!!" in place of reading stdout of child process.
Thanks,
Kevin Peterson
