Python Debugger Commands
Yog koj ua haujlwm nrog Python , tsis yog xwb tau koj saib dhau tus code thaum debugging, tab sis koj ua tau kuj khiav cov code uas tau sau rau hauv kab hais kom ua lossis txawm cuam tshuam cov txheej txheem los ntawm kev hloov pauv cov nqi sib txawv. Python muaj ib tug built-in debugger hu ua pdb
Yog li ntawd, koj yuav ua li cas debug kab los ntawm kab hauv Python?
Qee qhov tseem ceeb uas yuav tsum nco ntsoov yog:
- b: set ib breakpoint.
- c: txuas ntxiv debugging kom txog rau thaum koj ntaus lub breakpoint.
- s: kauj ruam dhau lub chaws.
- n: mus rau kab tom ntej no code.
- l: sau qhov chaws rau cov ntaub ntawv tam sim no (default: 11 kab nrog rau kab raug tua)
- u: navigate ib pawg ncej.
- d: mus rau hauv ib pawg ncej.
Kuj Paub, dab tsi yog qhov breakpoint hauv Python? Python breakpoint () yog ib tug tshiab built-in muaj nuj nqi qhia nyob rau hauv Python 3.7. Python code debugging yeej ib txwm ua tus txheej txheem mob vim yog nruj coupling ntawm tiag code thiab debugging module code. Piv txwv li, yog tias koj siv pdb debugger, ces koj yuav tau hu rau pdb. set_trace() hauv koj qhov program code.
Tsis tas li ntawd, kuv yuav ua li cas thiaj li khiav Python tsab ntawv kab los ntawm kab?
Siv python commandQhov yooj yim tshaj plaws thiab txoj kev yooj yim rau khiav Python scripts yog los ntawm kev siv lub python lus txib. Koj yuav tsum qhib qhov hais kom ua- kab thiab ntaus lo lus python ua raws li txoj kev mus rau koj tsab ntawv file, zoo li no: python first_script.py Nyob zoo ntiaj teb no! Tom qab ntawd koj ntaus lub pob ENTER los ntawm cov keyboard thiab qhov ntawd yog nws.
Kuv yuav ua li cas debug Python code hauv Visual Studio?
Xaiv cov cuab yeej> Xaiv cov ntawv qhia zaub mov hais kom ua, mus rau Python > Kev debugging , thiab xaiv qhov Use legacy debugger kev xaiv. Yog hais tias koj tau nruab ib tug laus version ntawm ptvsd nyob rau hauv lub tam sim no ib puag ncig (xws li ib tug ua ntej 4.0. x version, los yog ib tug 3. x version yuav tsum tau rau tej thaj chaw deb debugging ), Visual Studio tej zaum yuav qhia qhov yuam kev lossis ceeb toom.

Yog lawm. Flowcoat yog lub tsho sab saum toj rau fiberglass. Lub layup tawm mus nplaum, thiab cov flowcoat (tseem hu ua sanding coat) smooths tawm lub layup thiab tsis nplaum, cia koj xuab zeb nws thiab polish nws
Koj puas tuaj yeem ua tsis tiav MBE thiab tseem hla lub bar?
Cov lus teb, hauv ntau lub xeev, yog yog. Hauv ntau lub xeev, raws li koj ua rau cov ntsiab lus poob ntawm cov ntawv sau ntawm qhov kev xeem, koj tuaj yeem ua tsis tiav MBE thiab tseem dhau qhov barexam. Piv txwv li, hauv New York, koj xav tau 266 tawm ntawm 400 lub ntsiab lus kom dhau qhov kev xeem bar
Koj puas tuaj yeem dhau tus pointer los ntawm kev siv C ++?
Kev Tshaj Tawm Txog Tus Pointer hauv C ++ Ceeb Toom: Nws raug tso cai siv "pointer rau pointer" hauv ob qho tib si C thiab C ++, tab sis peb tuaj yeem siv "Reference to pointer" nkaus xwb hauv C ++. Yog tias tus pointer tau dhau mus rau qhov ua haujlwm raws li qhov ntsuas thiab sim hloov kho, qhov kev hloov pauv tau ua rau tus pointer tsis cuam tshuam rov qab rau sab nraud qhov haujlwm ntawd
Koj puas tuaj yeem dhau qhov ntsuas mus rau qhov pom?
Yog tias koj yuav tsum tau siv tus neeg siv lub luag haujlwm uas koj tuaj yeem dhau qhov ntsuas mus rau. Tsis yog, kev saib yog nug tsis txawv rau SELECTing los ntawm lub rooj. Ib qho kev pom tsis muaj dab tsi ntau dua li cov lus hais 'SELECT' tau ua tiav. Yog li tib lo lus teb tiag tiag yuav yog: Tsis yog, koj ua tsis tau
Koj puas tuaj yeem render dhau qhov render uas twb muaj lawm?
1. Cov renders uas twb muaj lawm feem ntau ua tiav nrog cov txheej nyias nyias lossis cov xim pleev xim uas yuav tsim ib qho kev cuam tshuam tsis muaj zog uas tsis haum rau rendering dhau. Cov khoom qias neeg tuaj yeem khaws cia rau ib lub sijhawm tuaj yeem tsim cov txheej txheem nruab nrab tsis muaj zog uas cuam tshuam nrog kev txhim kho ntawm daim ntawv cog lus ntawm kev thov tshiab
