Python los ntawm nws tus kheej tsis yog kev tshwm sim-tsav thiab natively asynchronous (zoo li NodeJS), tab sis tib lub txiaj ntsig tseem tuaj yeem ua tiav.

Ib yam li ib tug yuav nug, puas yog Python thov synchronous?

1 Teb. Zoo li feem ntau Python cov khoom, tshwj tsis yog hais meej meej, urlib2 yog synchronous . Yog li qhov kev tua yuav thaiv kom txog thaum lub server teb. Yog li yog tias koj xav ua 30,000 thov , koj yuav tau ua ib tug thov tom qab lwm tus.

Ib yam li ntawd, Python asynchronous lossis synchronous? Hauv synchronous ntiaj teb, lub Python uas tau nyob ib ncig ntawm ntau xyoo lawm, koj hu xov tooj ncaj qha thiab txhua yam tau ua tiav raws li nws tau sau rau ntawm qhov screen. Koj tsuas yog built-in kev xaiv rau khiav code nyob rau hauv parallel nyob rau hauv tib txoj kev yog threads. Hauv asynchronous ntiaj teb no, tej yam hloov me ntsis.

Li ntawd, puas tuaj yeem asynchronous Python?

Async IO yog ib qho kev sib koom ua ke tsim qauv uas tau txais kev txhawb siab rau hauv Python , evolving sai heev los ntawm Python 3.4 txog 3.7, thiab tej zaum dhau mus. Tej zaum koj yuav xav nrog dread, Concurrency, parallelism, threading, multiprocessing.

Puas yog Python thov raug thaiv?

Zoo li urlib2, thov yog thaiv . Tab sis kuv tsis xav kom siv lwm lub tsev qiv ntawv, ib yam nkaus. Cov lus teb yooj yim tshaj yog khiav txhua thov nyob rau hauv ib txoj xov sib cais. Tshwj tsis yog tias koj muaj ntau pua ntawm lawv, qhov no yuav tsum zoo.
