Python / Selenium : ERRNO 111 when I call my function multiple times
Question
I'm currently learning python and I struggle with multiple calls of a function using selenium with geckodriver.
This code is working well when I use it a single time :
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.common.exceptions import WebDriverException
from selenium.webdriver.firefox.options import Options
import time
import sms
options = Options()
options.add_argument("--headless")
profile = webdriver.FirefoxProfile()
profile.set_preference("dom.disable_beforeunload", True)
browser = webdriver.Firefox(firefox_options=options, firefox_profile=profile)
timeout=10
def busETA(trajet):
if trajet == "aller" :
print('Recherche en cours du trajet aller...')
Arret="Maison de retraite"
#URL BONNEVILLE => CHAL
URL='https://pysae.com/info/#/sm4cc/map/stop/5'
browser.get(URL)
#URL CHAL => BONNEVILLE
#Arrêt Maison de retraite
try :
EtaPresent = EC.presence_of_element_located((By.CSS_SELECTOR, '.firstTime > span:nth-child(1)'))
WebDriverWait(browser,timeout).until(EtaPresent)
ETA = browser.find_element_by_css_selector('.firstTime > span:nth-child(1)').text
if "H" not in ETA:
ETA=ETA+' min'
reponse = 'Le prochain bus arrivera dans '+str(ETA)+" à l'arrêt: "+Arret
except WebDriverException as e:
try :
ETA = browser.find_element_by_css_selector('.text-endService').text
reponse=ETA
except WebDriverException as e:
print("Error aller")
ETA="Erreur"
pass
finally :
browser.quit()
elif trajet =="retour" :
print('Recherche en cours du trajet retour...')
Arret="CHAL"
URL='https://pysae.com/info/#/sm4cc/map/stop/10'
browser.get(URL)
#Arrêt CHAL
try :
EtaPresent = EC.presence_of_element_located((By.CSS_SELECTOR, '.routes-view > footer:nth-child(2) > div:nth-child(1) > div:nth-child(3) > div:nth-child(1) > span:nth-child(3) > span:nth-child(1) > span:nth-child(1)'))
WebDriverWait(browser,timeout).until(EtaPresent)
ETA= browser.find_element_by_css_selector('.routes-view > footer:nth-child(2) > div:nth-child(1) > div:nth-child(3) > div:nth-child(1) > span:nth-child(3) > span:nth-child(1) > span:nth-child(1)').text
if "H" not in ETA:
ETA=ETA+' min'
reponse = 'Le prochain bus arrivera dans '+str(ETA)+" à l'arrêt: "+Arret
except WebDriverException as e:
try :
ETA = browser.find_element_by_css_selector('.text-endService').text
reponse=ETA
except WebDriverException as e:
print("Erreur retour")
ETA="Erreur"
browser.quit()
pass
finally :
browser.quit()
print(reponse)
#sms.sendsms(reponse,'number')
return
busETA('retour')
But If I call it more times like this:
busETA('retour')
busETA('aller')
busETA('retour')
I get this error :
Recherche en cours du trajet retour...
Le prochain bus arrivera dans 26 min à l'arrêt: CHAL

I must admit that I'm pretty new to python...
What did I get wrong ?
Any help will be greatly appreciated !

I've fixed the problem by calling the webdriver inside the function :
def busETA(trajet):
browser = webdriver.Firefox(firefox_options=options)
[...]
so every new call it re-open the browser !
In fact I was destroying the browser with browser.quit() without opening it again, causing the ERRNO 111 error.
