Cov sim thiab tsuas yog thaiv hauv Python yog siv los ntes thiab lis kev zam. Python executes code tom qab lub sim nqe lus raws li ib feem "ib txwm" ntawm qhov kev zov me nyuam. Cov cai uas ua raws li cov lus qhia tshwj xeeb yog qhov kev pab cuam teb rau txhua qhov kev zam hauv qhov ua ntej sim lus.

Hais txog qhov no, sim ua dab tsi hauv Python?

Python txoj kev sim nqe lus yog ib txoj kev uas peb tuaj yeem siv los daws qhov yuam kev zoo. Yog hais tias qhov yuam kev raug daws kom raug, ua tiav cov cai ua tsis tsim cov xwm txheej yuam kev thiab tsis muaj qhov tso tawm rau stderr. Cov saum toj no tawm nrog xwm txheej = 0 thiab tsis muaj qhov tso tawm rau stderr.

Kuj Paub, thaum siv sim tsuas yog? A sim block tso cai rau koj los daws qhov xav tau yuam kev. Cov tsuas yog block yuav tsum xwb ntes kev zam uas koj tau npaj los daws. Yog tias koj daws qhov yuam kev tsis txaus ntseeg, koj tus lej yuav ua qhov tsis raug thiab zais cov kab.

Tsis tas li ntawd, koj sau li cas tshwj tsis yog hauv Python?

Python Sim Except

  1. Qhov sim thaiv yuav tsim qhov kev zam, vim tias x tsis tau txhais:
  2. Sau ib cov lus yog qhov sim thaiv tsa lub NameError thiab lwm yam rau lwm yam yuam kev:
  3. Hauv qhov piv txwv no, sim block tsis tsim ib qho yuam kev:
  4. sim:
  5. Sim qhib thiab sau rau cov ntaub ntawv uas sau tsis tau:

Peb puas tuaj yeem muaj ntau yam sim blocks hauv Python?

Koj ua tau ntes ntau kev zam nyob rau hauv ib qho kev zam thaiv . Saib cov piv txwv hauv qab no. Thov nco ntsoov tias koj ua tau cais cov kev zam los ntawm qhov sib txawv nrog ib tug comma uas muaj feem xyuam rau hauv Python 2.6/2.7. Tab sis koj ua tau 't ua nws hauv Python 3.
