JSON hauv Python

Python muaj ib JSON module tias yuav pab hloov cov datastructures rau JSON hlua. Siv lub ntshuam muaj nuj nqi rau import tus JSON module. Cov JSON module yog feem ntau yog siv los hloov cov python phau ntawv txhais lus saum toj no rau hauv a JSON txoj hlua ntawd ua tau sau rau hauv ib daim ntawv

Ib yam li ntawd, koj tuaj yeem nug, Python ua haujlwm li cas JSON cov ntaub ntawv?

Kev tawm dag zog

  1. Tsim cov ntaub ntawv Python tshiab rau JSON import.
  2. Crate ib phau ntawv txhais lus nyob rau hauv daim ntawv ntawm ib txoj hlua siv raws li JSON.
  3. Siv JSON module los hloov koj txoj hlua rau hauv phau ntawv txhais lus.
  4. Sau ib chav kawm kom thauj cov ntaub ntawv los ntawm koj txoj hlua.
  5. Instantiate ib yam khoom los ntawm koj chav kawm thiab luam ib co ntaub ntawv los ntawm nws.

Ib yam li ntawd, koj yuav pov tseg cov ntaub ntawv JSON hauv Python li cas? 2. Muab Python Dict Rau JSON Cov Ntaub Ntawv lossis Load Dict Los Ntawm JSON Cov Ntaub Ntawv.

  1. Hu rau txoj kev qhib kom tau txais cov khoom siv.
  2. Hu rau json. dump(dict_object, file_object) khaws cov ntaub ntawv dict rau JSON cov ntaub ntawv. import json # Txuag ib qho python dict object rau JSON hom ntawv.

Ua raws li qhov no, koj sau JSON hauv Python li cas?

Txhawm rau tswj cov ntaub ntawv ntws hauv cov ntaub ntawv, lub JSON tsev qiv ntawv hauv Python siv dump() lossis dumps() ua haujlwm los hloov cov Python khoom nyob rau hauv lawv tus kheej JSON khoom, yog li nws ua kom yooj yim rau sau cov ntaub ntawv rau cov ntaub ntawv. Saib cov lus qhia hauv qab no.
