Python激活同名窗口

Question

选择器.org fn是错误的，应该.org.fn选择所有具有 classorg和 的元素fn。

但是，有些项目没有.address这样，您的代码会产生倾斜的结果。您可以使用此示例来获取标题和地址（如果缺少地址，-则使用 ）：

import pprint

import requests

from itertools import chain

from bs4 import BeautifulSoup

res = requests.get('https://www.paginebianche.it/toscana/li/gommisti.html')

res2 = requests.get('https://www.paginebianche.it/ricerca?qs=gommisti&dv=li&p=2')

soup = BeautifulSoup(res.text, 'html.parser')

soup2 = BeautifulSoup(res2.text, 'html.parser')

hn = []

for i in chain.from_iterable([soup.select('.item'), soup2.select('.item')]):

    title = i.h2.getText(strip=True)

    addr = i.select_one('[itemprop="address"]')

    addr = addr.getText(strip=True, separator='\n') if addr else '-'

    hn.append({'title': title, 'address': addr})    

pprint.pprint(hn)

印刷：

...and so on.

要循环选择窗口，需要执行以下几个步骤：使用win32gui.EnumWindows遍历所有打开的窗口使用win32gui.GetWindowText从窗口获取标题栏文本使用win32com.client.Dispatch和SendKeys激活切换过程使用win32gui.SetForegroundWindow选择要激活的窗口这是代码：import win32com.client as win32import win32guiimport timetitle = "Untitled - Notepad2"  # cycle all windows with this titledef windowEnumerationHandler(hwnd, top_windows):    top_windows.append((hwnd, win32gui.GetWindowText(hwnd)))    top_windows = []  # all open windowswin32gui.EnumWindows(windowEnumerationHandler, top_windows)winlst = []  # windows to cycle throughfor i in top_windows:  # all open windows   if i[1] == title:      winlst.append(i)      for x in range(5):  # cycle 5 times   for w in winlst:  # each window with selected title       shell = win32.Dispatch("WScript.Shell")  # set focus on desktop       shell.SendKeys('%')  # Alt key       win32gui.SetForegroundWindow(w[0]) # bring to front, activate       time.sleep(2)  # 2 seconds
