Question

我不是程序员，所以如果我不准确或不太理解回复，请多多包涵。

我使用 PyCharm ，它对我来说效果很好，python 脚本在 PyCharm 中被称为项目，我正在运行几个网页抓取脚本来检索互联网上的竞争对手价格。它们非常简单，但效果很好。为了完成这个过程，我必须独立地调用每个脚本（每个竞争对手一个），等待它完成，然后我调用另一个，等等。我实际上可以同时调用或运行所有这些脚本，但它在视觉上变得非常凌乱，有时会出现错误，一次运行一个并获得结果更简单，每次运行需要 10-15 分钟。

但我不能坐等他们完成。我尝试将它们合并到一个大项目中，但这真的很混乱，因为每个网页都有细微差别，差异，我为每个页面使用不同的变量以允许差异，这种方式更简单。但这很耗时，而且基本上迫使我在运行它们时保持原地不动。

我正在尝试自动化该过程，并且正在使用 TkInter 编写一个小项目，该项目将（理想情况下）一次一个地调用或运行每个项目，并且我还希望从每个项目中检索退出代码运行，以便我知道项目/脚本是否正常运行。

我已经对 TkInter semi 进行了整理，并设法让按钮、时钟等启动并运行（我计划每天运行此脚本四次，大约每 3 小时一次）。我有信心我可以做 GUI TkInter 位。

但是我一直无法从另一个 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（在按下 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。

这是我得到的错误：

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

如何以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？

我曾想尝试从每个项目/脚本中制作一个 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。

这是几行

# 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)

这些是接下来的几行，我出于显而易见的原因编辑了一些内容，但就像我之前所说的那样，一切都完美无缺

# 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")

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

库子进程参考：https://docs.python.org/3/library/subprocess.html

一些例子：https://www.programcreek.com/python/example/50/subprocess.Popen 和https://www.programcreek.com/python/example/50/subprocess.run
