Python：从Excel到Web到PDF

Question

我是编程新手，正在寻找从城市网站提取一系列水费账单PDF的最佳方法。 我已经能够打开网页并能够使用excel列表中的帐号来开设帐户，但是，我无法创建一个循环来遍历所有帐户而无需重写代码。 我有一些想法，但我想存在更好的建议。 参见下面的介绍代码：

import bs4, requests, openpyxl, os

os.chdir('C:\\Users\\jsmith.ABCINC\\Desktop')

addresses = openpyxl.load_workbook ('WaterBills.xlsx')
type (addresses)
sheet = addresses.get_sheet_by_name ('Sheet1')
cell = sheet ['A1']
cell.value

from selenium import webdriver
browser = webdriver.Firefox()
browser.get('https://secure.phila.gov/WRB/WaterBill/Account/GetAccount.aspx')
elem = browser.find_element_by_css_selector('#MainContent_AcctNum')
elem.click()
elem.send_keys (cell.value)
elem = browser.find_element_by_css_selector('#MainContent_btnLookup')
elem.click()

谢谢你的协助！

找不到下载PDF的好方法，但是除了以下内容之外：

    import openpyxl

    from selenium import webdriver


    workbook        = openpyxl.load_workbook('WaterBills.xlsx')
    sheet           = workbook.get_sheet_by_name('Sheet1')
    column_a        = sheet.columns[0]
    account_numbers = [row.value for row in column_a if row.value]

    browser = webdriver.Firefox()
    browser.get('https://secure.phila.gov/WRB/WaterBill/Account/GetAccount.aspx')

    for account_number in account_numbers:
        search_box = browser.find_element_by_id('MainContent_AcctNum')
        search_box.click()
        search_box.send_keys(account_number)

        search_button = browser.find_element_by_id('MainContent_btnLookup')
        search_button.click()

        # TODO: download the page as a PDF

        browser.back()

    browser.quit()
