I can`t see the content of tables with pyodbc

I am trying to print all the lines of a database, it does not give me an error, but it does not print either. I don't know where the error is.

import pyodbc

try:
    conexion = pyodbc.connect('DRIVER=ODBC Driver 17 for SQL Server;SERVER=DESKTOP-NPCMMNO\SQLEXPRESS01;DATABASE=Farmatic;UID=sa;PWD=farmatic')
    print('Conectado')
except:
    print('error al intentar conectarse')

#consulta a la base de datos
cursor = conexion.cursor()
cursor.execute("SELECT * from dbo.InventaMA;")

inventario = cursor.fetchone()

while inventario:
    print(inventario)
    inventario = cursor.fetchone()


cursor.close()
conexion.close()
'''
