I want to execute multiple functions and make them run separately but all the processes wait for the previous function to complete. This is a problem because, for example, backgroundLoader() in the code runs forever, so all functions after it will never run.
#!/usr/bin/env python
from multiprocessing import Process, Pool
from os import listdir, system
from os.path import isfile, join
from time import time, sleep
import random
def is_connected():
try:
# connect to the host -- tells us if the host is actually
# reachable
print('checking in 5 s....')
sleep(5)
create_connection(("www.duckduckgo.com", 80))
return True
except OSError:
pass
return False
def backgroundLoader():
filesInDir = [f for f in listdir('/home/homee/Pictures/Backgrounds/') if isfile(join('/home/homee/Pictures/Backgrounds/', f))]
totalFiles = 0
fileArray = []
for f in filesInDir:
totalFiles += 1
fileArray.append(f)
while True:
randInt = random.randrange(0, totalFiles, 1)
system('feh --bg-scale /home/homee/Pictures/Backgrounds/' + fileArray[randInt])
print('changed background')
sleep(300)
def main():
pBackground = Process(target=backgroundLoader(), args=())
pNetwork = Process(target= is_connected(), args=())
procs = []
procs.append(pBackground)
procs.append(pNetwork)
for proc in procs:
proc.start()
if __name == '__main__':

You are running backgroundLoader() in the first line of main() instead of passing the function as the target.

obs... thanks! Fixed the issue by removing the parentheses from target=function() <--
