選擇器.org fn是錯誤的，應該.org.fn選擇所有具有 classorg和 的元素fn。但是，有些項目沒有.address這樣，您的代碼會產生傾斜的結果。您可以使用此示例來獲取標題和地址（如果缺少地址，-則使用 ）：import pprintimport requestsfrom itertools import chainfrom bs4 import BeautifulSoupres = 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：[{'address': 'Via Don Giovanni Minzoni 44\n-\n57025\nPiombino (LI)', 'title': 'CENTROGOMMA'}, {'address': 'Via Quaglierini 14\n-\n57123\nLivorno (LI)', 'title': 'F.LLI CAPALDI'}, {'address': 'Via Ugione 9\n-\n57121\nLivorno (LI)', 'title': 'PNEUMATICI INTERGOMMA GOMMISTA'}, {'address': "Viale Carducci Giosue' 88/90\n-\n57124\nLivorno (LI)", 'title': 'ITALMOTORS'}, {'address': 'Piazza Chiesa 53\n-\n57124\nLivorno (LI)', 'title': 'Lo Coco Pneumatici'}, {'address': '-', 'title': 'PIERO GOMME'}, {'address': 'Via Pisana Livornese Nord 95\n-\n57014\nVicarello (LI)', 'title': 'GOMMISTA TRAVAGLINI PNEUMATICI'}, {'address': 'Via Cimarosa 165\n-\n57124\nLivorno (LI)', 'title': 'GOMMISTI CIONI AUTORICAMBI & SERVIZI'}, {'address': 'Loc.

要循環選擇窗口，需要執行以下幾個步驟：
使用win32gui.EnumWindows遍歷所有打開的窗口
使用win32gui.GetWindowText從窗口獲取標題欄文本
使用win32com.client.Dispatch和SendKeys激活切換過程
使用win32gui.SetForegroundWindow選擇要激活的窗口
這是代碼：
import win32com.client as win32
import win32gui
import time
title = "Untitled - Notepad2" # cycle all windows with this title
def windowEnumerationHandler(hwnd, top_windows):
top_windows.append((hwnd, win32gui.GetWindowText(hwnd)))
top_windows = [] # all open windows
win32gui.EnumWindows(windowEnumerationHandler, top_windows)
winlst = [] # windows to cycle through
for 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
