Here is a class I wrote to get billboard hot 100 songs by date.
The class uses requests to get website html text
It then uses beautifulsoup to parse the html
The parsing works well
the problem is the intermittent connection errors
import json
import time
from bs4 import BeautifulSoup
import requests
import datetime as DT
class BillBoardScraper():
def __init__(self) -> None:
self.top_100 = None
self.scraped_chart = None
def _scrape_chart(self, date):
url = 'https://www.billboard.com/charts/hot-100'
headers = {
"User-Agent": "Mozilla/5.0"
}
r = requests.get(
f'{url}/{date}', headers=headers)
bill_board_100_soup = BeautifulSoup(r.text, 'html.parser')
r = None
bill_board_100_results_soup = bill_board_100_soup.find_all(
"div", "o-chart-results-list-row-container")
return bill_board_100_results_soup
def _get_song_and_artist(self, idx):
for result_item in self.scraped_chart[idx].find_all('li'):
segment_struct = [tag.name for tag in result_item if tag.name]
if segment_struct == ['h3', 'span']:
song_and_artist = []
for tag in result_item:
if tag.string.strip():
song_and_artist.append(tag.string.strip())
return song_and_artist
def run_parser_and_archive_data(self, date):
self.top_100 = {}
self.scraped_chart = self._scrape_chart(date)
for i in range(0, 100):
song, artist = self._get_song_and_artist(i)
self.top_100[i+1] = {"track": song, "artist": artist, "date": date}
json_string = json.dumps(self.top_100)
with open(f'data_billboard/billboard_hot100_{date}.json', 'w') as outfile:
json.dump(json_string, outfile)
date = DT.date(2010, 3, 19)
n_weeks = 520
c_week = 1
while c_week <= n_weeks:
print(str(date))
top100 = BillBoardScraper()
top100.run_parser_and_archive_data(str(date))
date = date - DT.timedelta(days=7)
time.sleep(10)
Sporadically I receive the following error. Why does this happen? What can I do to mitigate this? Any feedback is appreciated

I am looking to retrieve some tweets using some search terms. After collection of around 25,000 tweets, it started producing timeout error. FYI, I am using Academic Research account and Twitter API v1.
I want to understand the cause of the error so that I can retrieve more tweets.
Following is my scraping script:
def scrape(words, orig_text):
# search for tweets between 2015 and 2018
start = datetime.datetime(2015, 1, 1)
end = datetime.datetime(2018, 12, 31)
db = pd.DataFrame(columns=['text', 'hashtags', 'search tag', 'id'])
tweets = tweepy.Cursor(api.search_tweets, q=words, lang="en", tweet_mode='extended').items(25000)
list_tweets = [tweet for tweet in tweets]
for i, tweet in enumerate(list_tweets):
tweet_id = tweet.id
hashtags = tweet.entities['hashtags']
Following is how I make connection:
auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_key, access_secret)
api = tweepy.API(auth, wait_on_rate_limit=True)
Following is the traceback for the error:
Rate limit reached. Sleeping for: 1013
Rate limit reached. Sleeping for: 1014

So basically this all stems from a previous question I had, so I'll post that question & my edit in its entirely below:
So I have a script I've been working with for a few days trying to get a list of emails from a csv I have, but now I've run into this roadblock. Here is the code:
import sys
try:
import urllib.request as urllib2
except ImportError:
import urllib2
import re
import csv
list1 = []
list2 = []
list3 = []
def addList():
with open('file.csv', 'rt') as f:
reader = csv.reader(f)
for row in reader:
for s in row:
list2.append(s)
def getAddress(url):
http = "http://"
https = "https://"
if http in url:
return url
elif https in url:
return url
else:
url = "http://" + url
return url
def parseAddress(url):
global list3
try:
website = urllib2.urlopen(getAddress(url))
html = website.read()
addys = re.findall('''[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*#(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?''', html, flags=re.IGNORECASE)
global list1
list1.append(addys)
except urllib2.HTTPError as err:
print ("Cannot retrieve URL: HTTP Error Code: "), err.code
list3.append(url)
except urllib2.URLError as err:
print ("Cannot retrive URL: ") + err.reason[1]
list3.append(url)
def execute():
global list2
addList()
totalNum = len(list2)
atNum = 1
for s in list2:
parseAddress(s)
print ("Processing ") + str(atNum) + (" out of ") + str(totalNum)
atNum = atNum + 1
print ("Completed. Emails parsed: ") + str(len(list1)) + "."
### MAIN
def main():
global list2
execute()
global list1
myFile = open("finishedFile.csv", "w+")
wr = csv.writer(myFile, quoting=csv.QUOTE_ALL)
for s in list1:
wr.writerow(s)
myFile.close
global list3
failFile = open("failedSites.csv", "w+")
write = csv.writer(failFile, quoting=csv.QUOTE_ALL)
for j in list3:
write.writerow(j)
failFile.close
main()
and when I run it I get this error:

File "/usr/lib/python3.5/re.py", line 213, in findall
return _compile(pattern, flags).findall(string)

So I've figured out that I need to figure out how to encode the html string into bytes for the encoding, and Tyler's answer below helped me do so but now I'm getting this error:

Does this mean that one of the urls from the list isn't a valid url? I thought I had finally removed all fo the bad urls from my csv file but I may need to take another look
I want to extract the covers for different journals on the cambridge university press website. The I want to save it as it's online ISSN. The following code works but after one or two journals, it gives me this error:

What am I doing wrong? I could not find any answers on google. It was working fine before.
Thank you in advance.

You should simplify your code and your scraping strategy, although I can see that not all journal pages have the same structure. On most pages you can get the ISSN easily through a form value. On others (free access, I think) you need to apply some kind of heuristics to get the ISSN. Also I don't know why you are using httplib2 and requests as both provide more or less the same functionality. Anyway here's some code that does what you want ... kind of (I have also removed the CSV code because as it is there's not need for that):
import requests
from bs4 import BeautifulSoup, SoupStrainer
with open('listoflinks.csv', encoding="utf8") as f:
for line in f:
path = line.strip()
print("getting", path)
response = requests.get("https://www.cambridge.org" + path)
soup = BeautifulSoup(response.text, "html.parser")
try:
issn = soup.find("input", attrs={'name': 'productIssn'}).get('value')
except:
values = soup.find_all("span", class_="value")
for v in values:
if "(Online)" in v.string:
issn = v.string.split(" ")[0]
break
print("issn:", issn)
details_container = soup.find("div", class_="details-container")
image = details_container.find("img")
imgurl = image['src'][2:]
print("imgurl:", imgurl)
with open(issn + ".jpg", 'wb') as output:
output.write(requests.get("http://" + imgurl).content)
