Changing the value of a dictionary item in Python

You can change the value of a dictionary element by its key. To do this, after specifying the key, after the operator =, we write the new value.

Let's look at an example. Let's say we have the following dictionary:

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

Let's change its element:

dct['a'] = '!'

Let's look at the changed dictionary:

print(dct) # {'a': '!', 'b': 2, 'c': 3}

Given a dictionary:

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

Increment the element with key 'x' by one.

Given a dictionary:

dct = {
	'surn': 'smit',
	'name': 'john'
}

Change the values for the keys 'surn' and 'name' to your last name and first name.
