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:\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:

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!

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?

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.
SOLVED
I will start off with I've never dealt with HTTP requests, and I've tried a few examples that I saw here on the website, but none of them worked for my case.
I want to "activate" scripts that are on a hardware device that I am trying to control. The device has its own HTTP server and by using various URLs I can change its variables, such url looks like this:
http://ipofdevice/ScriptName?varName=varValue&varName2=varValue2&varNameN=varValueN
I am trying to figure out how can I "activate" such URLs with python and I've gotten as far as, that I have to use post requests (I think?) and here is what I've tried so far:
I have already checked a few other posts and tried sample codes from there, but none of them worked, one such post was this:
How to send POST request?
Here is are two sample codes that I have tried, but did not work:
from urllib.parse import urlencode
from urllib.request import Request, urlopen
url = "http://127.0.0.1/ScriptName"
post_fields = { 'testVar' : 'hello', 'secondVar' : 'fromPython' }
request = Request(url, urlencode(post_fields).encode())
json = urlopen(request).read().decode()
And the json line threw an exception with a very long Traceback

This is the code from my second attempt:
import requests
base_url = "http://127.0.0.1/ScriptName"
post_fields = { 'testVar' : 'hello', 'secondVar' : 'fromPython' }
response = requests.post(final_url, data=post_fields)
With an even much longer traceback, which I will not post simply because it adds too much clutter and I dont think its needed, since obviously I am doing something fundamentally wrong.
I dont need anything fancy, just to be able to run a link like the one in the beginning of the thread, I am not even sure if POST request is what I need.
In javascript I was able to do it like this (but javascript lacks other things that I need):
var wnd = window.open("http://127.0.0.1/ScriptName?var=val");
wnd.close();
e.preventDefault();

EDIT 2: Solved, turns out that I actually needed a GET request as #MrBean Bremen suggested , all I had to do was:
import requests
requests.get(myurl)
Try this
import requests
tesVar = hello
secondVar = fromPython
baseurl = "http://127.0.0.1/ScriptName?{'tesVar'}&{'secondVar'}"
response = requests.get(baseurl)
print(response)
I'm fetching OHLCV data from Binance via Binance api on AWS-EC2.
But sometime(once a couple of days) error "104, 'ECONNRESET'" occur and program stop.
The program written in Python3.7.3 and run on AWS-EC2
The code is following. But this code couldn't continue.
I want to continue the program running when any api or connection error occured.
How should I handle this error ?
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)
continue
..............
All error massege are following.

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.
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...
