错误：AttributeError：'NoneType' 对象没有属性 'text'

Question

i have to simillar codes, one has multithreading and the other one doesnt. the one that has multithreading is getting this error AttributeError: 'NoneType' object has no attribute 'text' while the other isnt, here is my code:

multithreading:

import threading
import requests
from bs4 import BeautifulSoup

symbolsfile = open("Stocklist.txt")

symbolslist = symbolsfile.read()

thesymbolslist = symbolslist.split("\n")

print (thesymbolslist)


print_lock = threading.Lock()

def th(ur):
    theurl = "http://money.cnn.com/quote/quote.html?symb=" + ur
    thepage = requests.get(theurl)
    soup = BeautifulSoup(thepage.content,"html.parser")
    textfind = soup.find('span',{"stream":"last_36276"})
    texttext = textfind.text
    with print_lock:
        print(textfind)

threadlist = []

for u in thesymbolslist:
    t = threading.Thread(target = th, args=(u,))
    t.start()

    threadlist.append(t)

for b in threadlist:
    b.join()

and the one without multithreading:

import requests
from bs4 import BeautifulSoup


theurl = "http://money.cnn.com/quote/quote.html?symb=" + "AAPL"
thepage = requests.get(theurl)
soup = BeautifulSoup(thepage.content,"html.parser")
textfind = soup.find('span',{"stream":"last_36276"})
texttext = textfind.text
print(texttext)

Answer 1

The multihreading code works perfectly fine on my system (Win10, Python 3.4-64bit) when symbolslist is set to ['AAPL'] . But the script crashes with the reported error when symbolslist is set to ['AAPL', 'IBM'] .

When inspecting the returned HTML code, you can see that once stream="last_151846" and once stream="last_36276" is used. When you change the textfind line to

textfind = soup.find('span',{"streamformat":"ToHundredth"})

or

textfind = soup.find('span',{"streamfeed":"SunGard"})

the code will work for those examples, and hopefully for the ones provided in Stocklist.txt .

If your problem includes pytube in version 11.0.1. I suggest you check this post:
