Unable to Import External Python Program with Selenium

I encounter a small problem using Selenium on Python. In my main script, which is the following (right down), I would just like to manage to execute another external python script.

import time, os
import re #regex
import uuid
import urllib
import subprocess, sys
import pyautogui
import PIL
from PIL import Image 
import unittest
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.ui import WebDriverWait as wait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.action_chains  import ActionChains
def download():
    urllib.urlretrieve(m, "images/imgOUI_"+unique_filename+".png")
    im = Image.open("images/imgOUI_"+unique_filename+".png")
    out = im.resize((int(ExtractResize), int(ExtractResize2)))
    out.save("images/ImgComplete_"+unique_filename+".png")
co = webdriver.ChromeOptions()
co.add_argument("--user-data-dir=C:\Users\Marshall\AppData\Local\Google\Chrome\User Data\Default")
browser = webdriver.Chrome(chrome_options = co) 
browser.get("http://*/")
browser.find_element_by_id('SubmitButton').click()
#----------Move iframe-------
try:
    wait(browser, 20).until(EC.frame_to_be_available_and_switch_to_it(browser.find_element_by_xpath('//iframe[contains(@src, "google.com/recaptcha")]')))
except:
    print("error")

[...]
while True:

    [...]
    link = wait(browser, 20).until(EC.presence_of_all_elements_located((By.XPATH, '//img[contains(@src, "https://www.google.com/recaptcha/api2/payload?")]')))
    listLink = [] 
    for k in link:
        m = k.get_attribute('src')
        if m in listLink:
            print("Already added")
        else:
        listLink.insert(0, m)
        test = k.value_of_css_property("height") 
        test2 = k.value_of_css_property("width")
        ExtractResize = test.replace('px', '')
        ExtractResize2 = test2.replace('px', '')

        unique_filename = str(uuid.uuid4())
        download() 

        dim = wait(browser, 20).until(EC.presence_of_element_located((By.XPATH, '//div[contains(@style, "width")]'))).get_attribute('style')
        int1, int2 = re.findall(r'\d+', dim)
        subprocess.check_call("cut.py", shell=True) #Here, i want execute my other script python

(I spent some moments of my code which seems useless to add, if necessary, I would add them!)

Here the code of cut.py:

import time
from se import *
import random
import PIL
import uuid
from PIL import Image 
def cut():
    im = Image.open("images/ImgComplete_"+unique_filename+".png")


    left = a
    top = b
    width = c
    height = d



    box = (left, top, left+width, top+height)



    area = im.crop(box)


    print area.size
    unique_filename = str(uuid.uuid4())
    print unique_filename
    area.save("images/Principales/IMGsepare_"+unique_filename+".png")



image_size = (int(ExtractResize), int(ExtractResize2))

portion_size = (int(int1), int(int2))

Test2 = image_size[0]/portion_size[0]
Test = image_size[0]/float(portion_size[0])

List = (0, 0, portion_size[0], portion_size[1])
a, b, c, d = List
while True:
    if a==0:
        cut()
    for mo in range(0, int(Test2)):
        a += portion_size[0]
        if a == (int(Test2) * portion_size[0]):
            break
        cut()
    if a == (int(Test2) * portion_size[0]): 
        if not Test2 == Test:

            a = (image_size[0] - portion_size[0])
            cut()
        a = 0


        if b == (int(Test2) * portion_size[0]) and not Test2 == Test: 
            b = (image_size[1] - portion_size[1])

        else:   
            if b == image_size[1]: 
                print("Break")
                break
            print b
            b += portion_size[0] 
            if b == (int(Test2) * portion_size[0]) and not Test2 == Test: 
                b = (image_size[1] - portion_size[1])
                print("Vient de reajuster le B")
            print b
        if b == image_size[1]: 
            print("Break")
            break               

So I tried several methods, such as the following:

• subprocess.call("cut.py", shell = False)
• os.system("start cut.py")
• execfile("cut.py")

In all these attempts, I noticed that my program adopted the same behavior: In fact, it simply turns on another blank google window, then nothing, nothing happens.

I do not understand at all what comes from this problem.

EDIT:

After several minutes I finally get an error, here is the screen:
