Hier ein Code-Beispiel für die wichtigsten Funktionen von DuckDB.
import duckdb as ddb
import pandas as pd
con = ddb.connect(':memory:')
con_p = ddb.connect('my_database.db')
con_p.execute('CREATE OR REPLACE TABLE telefonnummern(fullname VARCHAR,phone VARCHAR);')
con_p.execute("INSERT INTO telefonnummern VALUES ('Max Mustermann', '0123-4567890')")
print(con_p.sql('SHOW ALL TABLES'))
print(con_p.sql('SELECT * FROM telefonnummern;'))
ddb_object = con_p.sql('SELECT * FROM telefonnummern;')
df = ddb_object.to_df()
ddb_tuple = ddb_object.fetchall()
print(df)
print(ddb_tuple) |

Die Helligkeit des Bildschirms lässt sich auch recht einfach per Powershell setzen
powershell (Get-WmiObject -Namespace root/WMI -Class WmiMonitorBrightnessMethods).WmiSetBrightness(1,50) |
powershell (Get-WmiObject -Namespace root/WMI -Class WmiMonitorBrightnessMethods).WmiSetBrightness(1,50)
setzt die Helligkeit beispielsweise auf 50 Prozent.
