Is Python Requests Synchronous?
Python Requests is a popular HTTP library used for interacting with APIs and fetching data from websites. One of the questions that often arise regarding this library is whether it is synchronous or asynchronous.
What is Synchronous and Asynchronous?
Synchronous programming is the traditional way of programming where the code gets executed in a sequential manner. In synchronous programming, the program has to wait for a task to complete before moving on to the next task. Asynchronous programming, on the other hand, allows the program to move on to the next task without waiting for the previous task to complete.
Python Requests - Synchronous or Asynchronous?
Python Requests library is synchronous in nature. When we send a request using Requests, it blocks the application until it receives a response. This means that the application becomes unresponsive until the request is completed.
How to Make Python Requests Asynchronous?
If you want to make Python Requests asynchronous, you can use a different library like aiohttp. aiohttp is an asynchronous HTTP client/server framework for Python that allows you to send asynchronous HTTP requests. Using this library, you can send multiple requests at once without blocking the application.
# Example of making an asynchronous request using aiohttp
import aiohttp
import asyncio
async def fetch(session, url):
async with session.get(url) as response:
return await response.text()
async def main():
async with aiohttp.ClientSession() as session:
html = await fetch(session, 'https://www.example.com')
print(html)
loop = asyncio.get_event_loop()
loop.run_until_complete(main())
In the above code, we are using the aiohttp library to make an asynchronous HTTP request. We are creating a coroutine named 'fetch' that takes in a session and a URL as arguments. We are then using the 'session.get' method to make the HTTP request asynchronously. Finally, we are using the 'await' keyword to wait for the response to come back.
Overall, if you want to make asynchronous requests in Python, you should use a different library like aiohttp instead of Python Requests.
