in python

Jaar 3 - Module 2 - eindopdracht bonus: tkinter

vandaag gaan we...

 

  • Leren hoe je knoppen maakt met tkinter
  • gebruik tkinter voor de eindopdracht

De database opdracht

  • Gebruik, in principe, dezelfde klant en data
  • Bekijk je eind-Excelsheet en maak een verslag:
    • Hoe zou je deze tabellen en formules omzetten naar een database?
    • Welke Excel-dingen kun je nog niet in databases?
    • Zet dan de Excelsheet om naar een sql database

De database opdracht

  • Gebruik, in principe, dezelfde klant en data
  • Bekijk je eind-Excelsheet en maak een verslag:
    • Hoe zou je deze tabellen en formules omzetten naar een database?
    • Welke Excel-dingen kun je nog niet in databases?
    • Zet dan de Excelsheet om naar een sql database
  • Denk na wat voor gegevens je zou willen invoeren in de database
    • Welke gegevens staan er al in?
    • Welke gegevens zouden nog toegevoegd kunnen worden?
    • Maak met Python een interface om dit in te voeren
    • Beschijf ook alle extra's die je hebt gedaan

Fase 1 - Deadline 18 januari

  • Gebruik, in principe, dezelfde klant en data
  • Bekijk je eind-Excelsheet en maak een verslag:
    • Hoe zou je deze tabellen en formules omzetten naar een database?
    • Welke Excel-dingen kun je nog niet in databases?
    • Zet dan de Excelsheet om naar een sql database in repl

De opdracht - Fases

Fase 2 - Deadline 14 februari

 

Denk na wat voor gegevens je zou willen invoeren in de database

  • Welke gegevens staan er al in?
  • Welke gegevens zouden nog toegevoegd kunnen worden?
  • Maak met Python een interface om dit in te voeren

De opdracht - Fases

Python interface

 

  • Stel vragen met input()


     

  • Bedenk wat iemand allemaal kan antwoorden

naam = input('welke naam wil je invoeren?')
leeftijd = input(f'wat is de leeftijd van {naam}?')
antw = input('wil je de resultaten zien?')
if antw == 'ja':
  print(resultaten)
antw = input('wil je de resultaten zien [ja/nee]?')
while antw != 'ja' and antw != 'nee':
  print('antwoord astublieft met "ja" of met "nee"')
  antw = input('wil je de resultaten zien [ja/nee]?')
 
if antw == 'ja':
  print(resultaten)

Python interface

 

  • input() is de meest basic manier om te communiceren met een gebruiker
     

  • vaker wordt gebruik gemaakt van knoppen en invulschermen

Probeer eerst voorbeelden te begrijpen

  • Voer de code uit
     
  • Probeer regel voor regel te begrijpen wat er gebeurd
     
  • Pas iets aan in de code en bekijk het effect
     
  • Schrijf commentaar bij iedere regel code
