我創建了一個網站刮板將颳去黃頁所有信息(用於教育目的)爲什麼它跳過整個循環?
def actual_yellow_pages_scrape(link,no,dir,gui,sel,ypfind,terminal,user,password,port,type):
print(link,no,dir,gui,sel,ypfind,terminal,user,password,port,type)
r = requests.get(link,headers=REQUEST_HEADERS)
soup = BeautifulSoup(r.content,"html.parser")
workbook = xlwt.Workbook()
sheet = workbook.add_sheet(str(ypfind))
count = 0
for i in soup.find_all(class_="business-name"):
sheet.write(count,0,str(i.text))
sheet.write(count,1,str("http://www.yellowpages.com"+i.get("href")))
r1 = requests.get("http://www.yellowpages.com"+i.get("href"))
soup1 = BeautifulSoup(r1.content,"html.parser")
website = soup1.find("a",class_="custom-link")
try:
print("Acquiring Website")
sheet.write(count,2,str(website.get("href")))
except:
sheet.write(count,2,str("None"))
email = soup1.find("a",class_="email-business")
try:
print(email.get("href"))
EMAIL = re.sub("mailto:","",str(email.get("href")))
sheet.write(count,3,str(EMAIL))
except:
sheet.write(count,3,str("None"))
phonetemp = soup1.find("div",class_="contact")
try:
phone = phonetemp.find("p")
print(phone.text)
sheet.write(count,4,str(phone.text))
except:
sheet.write(count,4,str("None"))
reviews = soup1.find(class_="count")
try:
print(reviews.text)
sheet.write(count,5,str(reviews.text))
except:
sheet.write(count,5,str("None"))
count+=1
save = dir+"\\"+ypfind+str(no)+".xls"
workbook.save(save)
no+=1
for i in soup.find_all("a",class_="next ajax-page"):
print(i.get("href"))
actual_yellow_pages_scrape("http://www.yellowpages.com"+str(i.get("href")),no,dir,gui,sel,ypfind,terminal,user,password,port,type)
的代碼是我的刮板的上面部分。我在湯和for循環中創建了斷點,甚至沒有執行for循環的單行。沒有錯誤拋出。我試着打印1-10的數字,但它不工作,爲什麼?
謝謝
可能因爲'find_all'的結果是空的?你有沒有檢查過它? – Julien
因爲你迭代的內容可能是空的。 –
使用'print()'來查看變量中的含義。 – furas
