I am trying to parallelize requests to the Wikidata API using Python’s asyncio module. My current synchronous script does the following: I am trying to do the same using asyncio, to send requests asynchronously. From this blogpost and the documentation, I understood that I need something like: However, I did not manage to find how to add these payloads in

If I use a helping function for a discord.py command, should I use await to call my helping function or just transfer control to my async helper
I have a command that works to send multiple type of messages that follow the same structure but I am using a helping function to send the message. For simplicity, my code looks similar to this: Option 1: Option 2 is making every function async and calling helper with await. It is my first time creating a discord bot and
asyncio add_signal_handler not catching sigint or sigterm
I’m having some trouble debugging an issue, I have an asyncio project and I would like it to shutdown gracefully. When I run my code and send a KeyboardInterrupt or TERM signal from a different screen, nothing seems to happen and it doesn’t look like clean_loop is being called. EDIT: I think I was able to isolate the problem a
How to avoid “too many requests” error with aiohttp
Here’s a snippet of my parser code. It does 120 requests asynchronously. However, every response returns 429 “too many requests” error. How do I make it “slower”, so the api won’t reject me? Error: Answer Try to use asyncio.Semaphore:
Keep indefinite connections open on TCP server with asyncio streams?
I’m trying to understand how to use asyncio streams for multiple connections that will keep sending messages until a predefined condition or a socket timeout. Looking at Python docs, they provide the following example for a TCP server based on asyncio streams: What I’m trying to do is more complex and it looks more like so (a lot of it
How to nullify python asyncio global variables?
I am writing a personal Telegram Bot to collect statistics on my accounts market.csgo.com. The main task of the bot is to send async requests to the API and display information via Telegram. Everything works as it should, but the problem is with global variables, or rather, their incorrect counting. An example of one of my functions: Function result: Bot
Python asyncio, why doesn’t asyncio.FIRST_COMPLETED work as described?
Let’s say I have two functions which return similar results. I want to call both and take the results of whichever returns first. So lets say I have two async functions which wait 5 and 2 seconds like so: And I have a function which calls them like so: As you see the competition function uses asyncio.wait to run the
Asyncio Streams automatically restarts to read data even after writer.close() is run
I followed the tutorial in https://docs.python.org/3/library/asyncio-stream.html to read data from a sensor (TCP protocol, PC as the server): The program is supposed to finish after 1 second data transmission. However, the output is: It repeated automatically and infinitely. What is the reason for this and How could I solve it? Answer Problem serve_forever() listens to the port indefinitely. So, even
websocket await close vs await wait_closed
I’m using the websockets package on python and I’m opening a connection as a client, but NOT in a block context like this: I’m opening the connection like this: The thing is that I don’t under stand what is the right way to close the connection. The document explains here about await close() and await wait_closed(), but I don’t understand
Use tqdm progress bar with asyncio
I am trying to create a single progress bar that will be updated whenever an async task is done. I have the following code The above code generates a single progress bar as but it is not updated until all tasks are finished (it shows either 0% or 100% while there’s more than a single task) I also tried using
