Is Flask synchronous or asynchronous

In the synchronous world, the Python that’s been around for decades, you call functions directly and everything gets processed as it’s written on screen . Your only built-in option for running code in parallel in the same process is threads. In the asynchronous world, things change around a bit.19 Şub 2018

Asynchronous code has increasingly become a mainstay of Python development. Let’s walk through how to use the aiohttp library to take advantage of this for making asynchronous HTTP requests, which is one of the most common use cases for non-blocking code. …

It makes use of Python async features using asyncio/await provided in Python 3 . The time and queue modules have been replaced with the asyncio package. This gives your program access to asynchronous friendly (non-blocking) sleep and queue functionality.

Asynchronous routines are able to “pause” while waiting on their ultimate result and let other routines run in the meantime . Asynchronous code, through the mechanism above, facilitates concurrent execution. To put it differently, asynchronous code gives the look and feel of concurrency.

It’s the language, in python most apis are synchronous by default , and the async version is usually an “advanced” topic. If you were using nodejs, they would be async; even if using javascript, the reason ajax is asynchronous is because of the nature of the browser.

There are two basic types of methods in the Parallels Python API: synchronous and asynchronous. When a synchronous method is invoked, it completes executing before returning to the caller. An asynchronous method starts a job in the background and returns to the caller immediately .

Most server-side languages like Python, C#, Java, and PHP execute code dependently, so one line or an entire block succeeding depends on the success of the one that precedes it. This means they’re all synchronous by default .
