QUESTION
I have been trying to check the status of all these subdomains all at once and I have tried multiple techniques even grequests and faster than requests wasn't much helpful and then I started using asyncio with aiohttp and it is slower than normal requests library now. Also I checked that it wasn't actually sending the requests asynchronously rather it was sending one after another.
I know that "await resp.status" has issues because resp.status does not support await but I tried removing it and it's still the same.

grequests works fine for this, you don't have to use async if you don't want.

QUESTION
I'm trying to send simultaneous get requests with the Python requests module.
While searching for a solution I've come across lots of different approaches, including grequests, gevent.monkey, requests futures, threading, multi-processing...
I'm a little overwhelmed and not sure which one to pick, regarding speed and code-readibility.
The task is to download < 400 files as fast as possible, all from the same server. Ideally it should output the status for the downloads in terminal, e. g. print an error or success message per request.
...ANSWER
Answered 2021-May-27 at 12:48I would use threading as it is not necessary to run the downloads on multiple cores like multiprocessing does.
So write a function where requests.get() is in it and then start as a thread.
But remember that your internet connection has to be fast enough, otherwise it wouldn't be worth it.

I've been trying to do some API queries to get some missing data in my DF. I'm using grequest library to send multiple request and create a list for the response object. Then I use a for loop to load the response in a json to retrieve the missing data. What I noticed is that when loading the data using .json() from the list directly using notition list[0].json() it works fine, but when trying to read the list and then load the response into a json, This error comes up : JSONDecodeError: Expecting value: line 1 column 1 (char 0)

I have written a small api wrapper and i wanted to try to put it in a discord bot using discord.py. I tried using requests, grequests and aiohttp for the requests, but that didn't work. The code that is throwing the error is the following:
...ANSWER
Answered 2021-Jan-28 at 12:50requests.get() isn't asynchronous, so awaiting it is useless. However _get is, so to invoke it, you'd need to await it.
But requests.get is blocking, putting it in an async function won't solve the issue (at least I believe).
To work with API, you can use aiohttp:

I'm trying to create a script that checks all possible top level domain combinations based on a given root domain name.
What I've done is generate a list of all possible TLD combinations and what I want to do is make multiple HTTP requests, analyze its results and determine whether a root domain name has multiple active top level domains or not.
Example: A client of mine has this active domains:
- domain.com
- domain.com.ar
- domain.ar
I've tried using grequests but get this error:
...ANSWER
Answered 2020-Dec-16 at 15:28As I mentioned, you cannot put code as a parameter. What you want is to add a list and you can using an inline for loop, like this:
[url for url in urls]
It is called list comprehensions and more information about this can be found over here: https://docs.python.org/3/tutorial/datastructures.html#list-comprehensions

QUESTION
To briefly explain context, I am downloading SEC prospectus data for example. After downloading I want to parse the file to extract certain data, then output the parsed dictionary to a JSON file which consists of a list of dictionaries. I would use a SQL database for output, but the research cluster admins at my university are being slow getting me access. If anyone has any suggestions for how to store the data for easy reading/writing later I would appreciate it, I was thinking about HDF5 as a possible alternative.
A minimal example of what I am doing with the spots that I think I need to improved labeled.
...ANSWER
Answered 2020-Aug-29 at 03:57Generally when you have runaway memory usage with a Pool it's because the workers are being re-used and accumulating memory with each iteration. You can occasionally close and re-open the pool to prevent this but it's so common of an issue that Python now has a built-in parameter to do it for you...
Pool(...maxtasksperchild) is the number of tasks a worker process can complete before it will exit and be replaced with a fresh worker process, to enable unused resources to be freed. The default maxtasksperchild is None, which means worker processes will live as long as the pool.
There's no way for me to tell you what the right value is but you generally want to set it low enough that resources can be freed fairly often but not so low that it slows things down. (Maybe a minutes worth of processing... just as a guess)

Install grequests
You can use grequests like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
