8 Teb. Hais txog kev ua haujlwm raw, Python yog qhov tseeb qeeb dua tshaj Java, C# thiab C/C++. Txawm li cas los xij, muaj lwm yam tseem ceeb rau cov neeg siv / cov neeg soj ntsuam xws li kev siv tag nrhomemory, lub sijhawm pib pib, thiab lwm yam. Rau ntau yam, Python yog ceev txaus;)

Ib yam li ntawd, nws raug nug, vim li cas python suav tias qeeb?

Internally yog vim li cas Python code executes qeeb qeeb yog vim code yog txhais ntawm runtime es tsis txhob muab tso ua ke rau haiv neeg code ntawm compile lub sij hawm. Yog vim li cas vim li cas CPython tsis muaj JIT compiler twb yog vim qhov dynamicnature ntawm Python ua rau nws nyuaj rau sau.

Tsis tas li ntawd, Python puas qeeb dua Java? Python cov kev pab cuam feem ntau xav kom khiav qeeb dua Java cov kev pab cuam, tab sis lawv kuj siv sij hawm tsawg dua los tsim. Python cov kev pab cuam feem ntau yog 3-5 zaug luv dua tshaj sib npaug Java cov kev pab cuam. Qhov sib txawv no tuaj yeem raug ntaus nqi rau Python cov built-in cov ntaub ntawv qib siab thiab nws cov dynamic typing.

Khaws qhov no hauv kev pom, yog C lossis Python sai dua?

C yog ntau sai dua tshaj python . Python code yog txhais uas ua rau nws qeeb qeeb. Interpreted code yog ib txwm qeeb qeeb tshaj lub tshuab code ncaj qha, vim hais tias nws yuav siv sij hawm ntau ntau cov lus qhia nyob rau hauv thiaj li yuav siv aninterpreted kev qhia dua los ua ib tug tiag tiag machineinstruction.

Kuv yuav ua li cas kom ceev ib Python tsab ntawv?
