Adding an item to a dictionary in Python

You can add new elements to the dictionary. To do this, you need to write a value to the key that is not yet in the dictionary. Let's look at an example.

Let us have the following dictionary:

pythondct = {
  'a': 1,
  'b': 2,
  'c': 3
}

Let's add a new element to it with key 'x':

pythondct['x'] = '!'

Let's look at our dictionary:

pythonprint(dct) # {'a': 1, 'b': 2, 'c': 3, 'x': '!'}

pythondct = {
  'x': 1,
  'y': 2,
  'z': 3
}
