Ik heb eigenlijk geprobeerd een programma te schrijven dat e-mails naar een lijst met gebruikers stuurt. Ik heb het onderstaande programma uitgevoerd en het vertelt me dat TypeError: ‘dict’ object niet kan worden opgeroepen. Ik kan niet begrijpen wat hier mis is en hoe ik het kan oplossen. Ik weet dat het een lange code is, maar elke vorm van hulp zou op prijs worden gesteld. Ik heb misschien wat domme fouten gemaakt, maar ik kan er niet bij.

in python heb je twee manieren om toegang te krijgen tot waarden in een dictaat:
dict['key']dict.get('key')
dict('key')werkt niet.
