How can I add new keys to a dictionary?

Question

I just want to know, whether we can add a key to a python dictionary, once when it's created.

It doesn't appear to have an .add() function.

Answer 1

Try the following code:

d = {'key': 'value'}

print(d)

# {'key': 'value'}

d['mynewkey'] = 'mynewvalue'

print(d)

# {'key': 'value', 'mynewkey': 'mynewvalue'}
