I am very much new to coding python script, i wrote a code in python where the functions can scan a list of remote target but the threads dies quick, The problem is that the thread dies and code ends before the scan is entirely complete.

What I have tried:

for i in range(400):
	try:
		thread=consumer(quee)
		thread.setDaemon(True)
		thread.start()
	except:
		print "Working only with %s threads"%i
		break

Solution 1

You need to ensure that the main thread of your program does not terminate while child threads are active. See threading — Thread-based parallelism — Python 3.9.6 documentation[^].

[edit]
Note also that trying to run 400 threads together will slow your system down dramatically. Running more than 3 or 4 together wil not get your work done faster.
