Async tools for Python
Async Tools for Python.
Threading is the most simple thing, but because of GIL it’s useless for computation. Only use when you want to parallelize the access to a blocking resource, e.g. network.
Execute functions in parallel and collect results. Each function is executed in its own thread, all threads exit immediately.
- join(): Wait for all tasks to be finished, and return two lists:
- A list of results
- A list of exceptions
from asynctools.threading import Parallel def request(url): # ... do request return data # Execute pll = Parallel(request) for url in links: pll.job(url) # Starts a new thread # Wait for the results results, errors = pll.join()
Create a pool of threads and execute work in it. Useful if you do want to launch a limited number of long-living threads.
- join(): Wait for all tasks to be finished and return (results, errors) (same as with `Pool <#pool>`__)
- close(): Terminate all threads.
- __enter__, __exit__ context manager to be used with with statement
from asynctools.threading import Pool def request(url): # ... do long request return data # Make pool pool = Pool(request, 5) # Assign some job for url in links: pll.job(url) # Runs in a pool # Wait for the results results, errors = pll.join()
