How do I add values to a nested dictionary in Python?

How do I add values to a nested dictionary in Python?

You can add values to a nested dictionary by accessing the specific key and then updating its value. For example, if you have a dictionary like data = {'a': {'b': 1}}, you can add a value like this: data['a']['c'] = 2.

What if the nested dictionary doesn't exist yet?

If the nested dictionary doesn't exist, you can create it first. For example: data['a'] = {} before adding values. Then you can do data['a']['b'] = 1.

Can I add multiple values at once?

Yes, you can add multiple values by using the update() method. For example: data['a'].update({'b': 1, 'c': 2}).

What about using a loop to add values?

You can definitely use a loop! For instance, if you have a list of values, you can iterate through it and add each value to the nested dictionary.
