error handling for network disconnect error - python

I am using pyowm to get weather update after each minutes. If I disconnect my internet or low internet what error will be occure and how can i handle this error.For try..except method..what possible exception have to use...??
my code is....
import tkinter as tk
from tkinter import *
import pyowm
from PIL import ImageTk, Image
win=tk.Tk()
#frame_for_showing_weather.
weather_frame=Frame(win,bg='black',width='300',height='300')
weather_frame.place(x=0,y=0)
weath=Label(weather_frame,font=('Agency',100),fg='white',bg='black')
weath.place(x=10,y=10)
temp1=''
owm=pyowm.OWM('my api key')
def obs():
global temp1
observation = owm.weather_at_place('Barisal,BD')
w=observation.get_weather()
temp2=w.get_temperature('celsius')
if(temp2!=temp1):
temp1=temp2['temp']
weath.config(text=str(int(temp1))+chr(176))
print('Alhamdulillah,Yeah that is worked')
weath.after(60000,obs)
obs()
win.mainloop()
please someone explain...I am new at python.
if i drop my connection this big error occure...

Azure Instance with linux machine docker timing out on requests

I have a python script in a docker that runs and collects data from an api on a loop.
`for idx, items in enumerate(SearchList):
#get access token
access_token = GetPricingAccTok()
#request id to get results
reqid = RequestIdCompSearch(items, access_token)
#api to get results by doing a while loop appending results together till api returns 100% as completed percentage
Result = GetReqResults(reqid, access_token)
Pricings = GetPricingDict(Result)
filenamepricing = "pricinghistory/CorrectFormat/Pricings_Data_{idn}_{ts}.json".format(
idn = idx,
ts= dt.datetime.now().isoformat()
)
GetAzContainer().upload_blob(
name=filenamepricing,
data=json.dumps(obj= Pricings, indent=4),
blob_type='BlockBlob'
)
`
When i run and test this code locally on my windows machine it works well without an issue and completes the requests
but in the docker on azure container instance it then returns an error showing that the connection has timed out. Not sure what the difference is between the running it locally and in the docker that i then recieve this error.
I have tried addinng this code at the start
import socket
from urllib3.connection import HTTPConnection
HTTPConnection.default_socket_options =(HTTPConnection.default_socket_options + [
(socket.SOL_SOCKET, socket.SO_KEEPALIVE, 1) #Enables the feature
,(socket.SOL_TCP, socket.TCP_KEEPIDLE, 45) #Overrides the time when the stack willl start sending KeppAlives after no data received on a Persistent Connection
,(socket.SOL_TCP, socket.TCP_KEEPINTVL, 10) #Defines how often thoe KA will be sent between them
,(socket.SOL_TCP, socket.TCP_KEEPCNT, 60) #How many attemps will your code try if the server goes down before droping the connection.
]
)
but it still times out. showing the below error

Tornado: how to close file object if exception/error in data_received when streaming chunked data to file

I am running Tornado with stream_request_body and saving a file POST request to file on server. In prepare I create the file object and in post I close file object. How do I capture any error/exception in data_received so that I can close the file object properly?
from tornado.ioloop import IOLoop

#stream_request_body
class UploadHandler(RequestHandler):
def prepare(self):
self.file = open('uploaded_file', 'wb')
def data_received(self, chunk):
print(len(chunk))
self.file.write(chunk)
# force an exception
raise Exception('Error')
def post(self, *args, **kwargs):
self.file.close()
self.write('UPLOADED')
app = Application([(r'/upload', UploadHandler), ],
debug=True)
if __name__ == '__main__':
app.listen(7777)

104, Connection reset by peer. When sending multiple long http post requests

I have a kubernetes cluster (on GKE) which runs tornado.web.Application server, that calls heavy dask.distributed calculations on that cluster.
Now I want to test my server, and send it multiple requests at once, to see if it handles those requests as it should.
When I'm sending only one request, it does everything and behaves as expected, no matter how big the request is.
But when I send more than one request, after like 5 minutes (I also tried on server side just to sleep, without making any calculations and got the same results), I get the following:

And none of the requests returns.
How can I get the behaviour I need, without these errors?
I need a server that can handle many requests, and to test it from my computer.

Assuming that you are using python-binance module, most likely the error happens because you are trying to reuse the client after long time (server timeout). You can try to recreate the client first:
...
client = Client(api_key, api_secret)
while True:
...
try :
klines = client.get_historical_klines(ticker_symbol, Client.KLINE_INTERVAL_1MINUTE, _from_str, _until_str)
except BinanceAPIException as e:
print(e)
print('Something went wrong. Error occured at %s. Wait for 1 hour.' % (datetime.datetime.now().astimezone(timezone('UTC'))))
sleep(3600)
client = Client(api_key, api_secret)
continue
...
The reason is because the [Client][2] uses requests Session underneath which imply usage of urllib3's connection pooling. This connection pooling can not be reused after timeout.

Problems using PRAW (searching and posting)

I am trying to write a small program with PRAW the python library for Reddit API, and I am searching and posting to reddit greek content.
For example I have the following function:
def find_if_posted(usr, title, url):
for content in usr.search(title):
return True
for content in usr.search(url):
return True
return False
which tries to search if there is a post with the same title or url. usr is the reddit PRAW object. When it starts to search with the url I am getting the error:
Traceback (most recent call last):
File "C:\Users\hargikas\Dropbox\Private\src\reddit\auto_poster\leftist.py", line 133, in <module>
while (key is None) or find_if_posted(usr, key, content[key]):
File "C:\Users\hargikas\Dropbox\Private\src\reddit\auto_poster\leftist.py", line 86, in find_if_posted
for content in usr.search(url):

File "C:\Python34\lib\site-packages\praw\__init__.py", line 515, in get_content
root = page_data.get(root_field, page_data)
AttributeError: 'str' object has no attribute 'get'
Also when I am trying to post something (using the submit function) I get this error:
Traceback (most recent call last):
File "C:\Python34\lib\site-packages\requests\packages\urllib3\connectionpool.py", line 372, in _make_request

When I am searching using parameters of imgur.com or other "English" sites, I get no error. But when I use it over Greek sites, or posting Greek content I get the above errors.
Do you have an idea what I am doing wrong? I am a newbie with PRAW so any comment is appreciated. I am using Python 3.4.3 (v3.4.3:9b73f1c3e601, Feb 24 2015, 22:43:06) [MSC v.1600 32 bit (Intel)] on win32 and PRAW Version: 2.1.21
Thank you in advance!
Harry
