  <pre><code>    import sqlite3
  verbindung = sqlite3.connect(&quot;Datenbanken/geb3.db&quot;)
  zeiger = verbindung.cursor()
  zeiger.execute(&quot;&quot;&quot;CREATE TABLE IF NOT EXISTS people3(vorname VARCHAR(20), nachname VARCHAR(30), geburtstag DATE );&quot;&quot;&quot;)
  
  from tkinter import *
  from tkcalendar import Calendar, DateEntry
  
  root = Tk()
  
  
  
  def speichern():
      zeiger.execute(&quot;&quot;&quot;INSERT INTO people3 VALUES (?,?,?) &quot;&quot;&quot;, (eingabefeldvorname.get(), eingabefeldnachname.get(), eingabefelddatum.get()))
      
  
  
  
  Label(root, text = &quot;vorname&quot;).pack()
  eingabefeldvorname=StringVar()
  eingabefeld = Entry(root, textvariable = eingabefeldvorname, bg =&quot;red&quot;).pack()
  
  Label(root, text = &quot;nachname&quot;).pack()
  eingabefeldnachname = StringVar()
  eingabefeld = Entry(root, textvariable = eingabefeldnachname, bg =&quot;green&quot;).pack()
  
  Label(root, text = &quot;Geburtsdatum&quot;)
  
  
  eingabefelddatum= DateEntry(root, width = 20, textvariable = eingabefelddatum, bg =&quot;yellow&quot;).pack()
  
  konpf2 = Button(root, text = &quot;speichern&quot;, command = speichern).pack()
  root.mainloop()
  
  
  
  zeiger.execute(&quot;SELECT * FROM people3&quot;)
  inhalt = zeiger.fetchall()
  print(inhalt)
  
  
  def listeleeren():
       zeiger.execute(&quot;DELETE FROM people3&quot;) 
  
  listeleeren()
  
  
  verbindung.commit()
  verbindung.close()```
