I want to add an item to an existing dictionary in Python For example this is my dictionary default data item1 1 item2 2 I want to add a new item such that default data default data item3 3 How can I achieve this

Add a new item to a dictionary in Python

default_data['item3'] = 3

Easy as py.

Another possible solution:

default_data.update({'item3': 3})

which is nice if you want to insert multiple items at once.
