QUESTION
I've started learning playwright-python and the package playwright
has the two submodules async_api
and sync_api
. However I could not find any deeper description or discussion on their respective benefits and drawbacks. From their names I assume that the synchronous API calls are blocking and the asynchronous ones run in the background?
Are they different in their capabilities, i.e. are there scenarios in which the sync_api
cannot accomplish something you can do using the async_api
(or vice versa)?
ANSWER
Answered 2020-Dec-26 at 21:43The sync_api
is simply a wrapper around the asyncio_api
that abstracts asyncio usage away from you. As such, the capabilities are largely the same, but the async_api
may afford some more flexibility in complex scenarios (for example, in previous playwright-python releases the only way to run instances in a multi-threaded fashion on Unix + Python 3.7 was to use the async_api
for reasons I won't get into here).
Chances are you won't need that flexibility though, so I'd just suggest using whatever you're comfortable with.

You can use playwright-python 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.
