Run a process and kill it if it doesn't end within one hour

Question

I need to do the following in Python. I want to spawn a process (subprocess module?), and:

• if the process ends normally, to continue exactly from the moment it

Answer 1

Koodos to Peter Shinners for his nice suggestion about subprocess module. I was using exec() before and did not have any control on running time and especially terminating it. My simplest template for this kind of task is the following and I am just using the timeout parameter of subprocess.run() function to monitor the running time. Of course you can get standard out and error as well if needed:

from subprocess import run, TimeoutExpired, CalledProcessError

for file in fls:
    try:
        run(["python3.7", file], check=True, timeout=7200)  # 2 hours timeout
        print("scraped :)", file)
    except TimeoutExpired:
        message = "Timeout :( !!!"
        print(message, file)
        f.write("{message} {file}\n".format(file=file, message=message))
    except CalledProcessError:
        message = "SOMETHING HAPPENED :( !!!, CHECK"
        print(message, file)
        f.write("{message} {file}\n".format(file=file, message=message))
