如何从另一个Python项目调用Python项目

Question

我不是一个程序员，所以请容忍我，如果我不准确或不真正理解的答复

我使用PyCharm，它对我来说非常好，python脚本在PyCharm中被称为项目，我正在运行一些webscraping脚本来检索互联网上的竞争对手价格。它们很简单，但效果相当好。为了完成这个过程，我必须独立调用每个脚本（每个竞争对手一个脚本），等待它完成，然后调用另一个脚本，等等。我实际上可以同时调用或运行所有脚本，但它在视觉上非常混乱，有时会出现错误，一次运行一个脚本并获得结果更简单，他们每人需要10-15分钟

但我不能坐等他们结束。我试着把它们合并到一个大项目中，但那真的很混乱，因为每个网页都有细微差别，不同之处，我在每个页面上使用不同的变量来考虑差异，这样就更简单了。但这很费时，基本上迫使我在运行它们时呆在原地

我正在尝试自动化这个过程，并使用TkInter编写一个小项目，该项目（理想情况下）调用或运行每个项目，一次一个，我还希望从运行的每个项目中检索退出代码，以便我知道项目/脚本是否正常运行

我已经整理好了TkInter半成品，并成功地启动和运行了按钮、时钟等（我计划每天运行这个脚本四次，大约每3小时运行一次）。我有信心我能做到这一点

但我无法从另一个PyCharm项目调用/运行/导入PyCharm项目。这是我一直在尝试和使用的最后一次迭代（当按下TkInter GUI上的按钮时调用这些：

  # create button, link it to run web price scraper program
    webscraperbutton = Button(self, text="Run", command=self.run_price_scraper)
    # place button at (400,100)
    webscraperbutton.place(x=200, y=100)

def run_price_scraper(self):
    # exec(open('/Users/manuel/PycharmProjects/PriceScraper/main.py').read())
    # os.system("/Users/manuel/PycharmProjects/PriceScraper/main.py")
    # subprocess.call('/Users/manuel/PycharmProjects/PriceScraper/main.py', shell=True)

它们都是d，因为我一直在尝试各种组合，但到目前为止没有任何效果

以下是我得到的错误：

subprocess.call('/Users/manuel/PycharmProjects/PriceScraper/main.py', shell=True)

我如何以一种简单的方式调用或运行另一个PyCharm项目，让它运行并获得退出代码

我曾想过尝试用每个项目/脚本制作一个Python应用程序，并尝试调用一个应用程序，但我不知道这是否可行

这是台词

# Import Libraries
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.select import Select
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as ec
import pandas as pd


# Start the session
chrome_options = Options()

# Option to run Headless
# chrome_options.add_argument('--headless')

# Activate Chrome Selenium Driver
driver = webdriver.Chrome(executable_path='/Applications/System Utilities/chromedriver')
# Define maximum wait
wait = WebDriverWait(driver, 20)

接下来的几行我编辑了一些东西，原因很明显，但正如我之前所说的，所有的工作都完美无缺

# Site Login Function
def site_login():
    # Login Data
    username = "XXXXXXXXXX"
    password = "XXXXXXXXXX"

    driver.get('https://XXXXXXXXXXXX.com/')
    # Wait for element to be present
    wait.until(ec.visibility_of_element_located((By.ID, "okta-signin-username")))
    # Send Username
    driver.find_element_by_id("okta-signin-username").send_keys(username)
    # print("username")
    # Wait for element to be present
    wait.until(ec.visibility_of_element_located((By.ID, "okta-signin-password")))
    # Send Password
    driver.find_element_by_id("okta-signin-password").send_keys(password)
    # print("password")
    # Wait for element to be present
    wait.until(ec.element_to_be_clickable((By.ID, "okta-signin-submit")))
    # Click Signin
    driver.find_element_by_id("okta-signin-submit").click()
    # print("Click")

至于子流程，您是否尝试过明确定义文件应该由python启动，比如subprocess.run(['python3', '/Users/manuel/PycharmProjects/PriceScraper/main.py'], shell=True)
