How can I add new keys to a dictionary?

Question

Is it possible to add a key to a Python dictionary after it has been created?

It doesn\'t seem to have an .add() method.

Answer 1

The conventional syntax is d[key] = value, but if your keyboard is missing the square bracket keys you could also do:

d.__setitem__(key, value)

In fact, defining __getitem__ and __setitem__ methods is how you can make your own class support the square bracket syntax. See https://python.developpez.com/cours/DiveIntoPython/php/endiveintopython/object_oriented_framework/special_class_methods.php
