Getting Key-Value Pairs from Dictionary in Python

You can also get all the elements from a dictionary as a list of tuples containing key-value pairs. For this, the items method is used, which returns a special dict_items object.

Let's look at it in practice. Let's say we have the following dictionary:

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

Let's output all the elements from it:

res = dct.items()
print(res) # dict_items([('a', 1), ('b', 2), ('c', 3)])

The dict_items object can be converted to a real list of tuples using the list function:

res = list(dct.items())
print(res) # [('a', 1), ('b', 2), ('c', 3)]

Given a dictionary:

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

Get all its elements.

Given a dictionary:

dct = {
	'a': [2, 4],
	'b': [3, 5]
}

Get all its elements.

Given a dictionary:

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

Get a list of tuples of its elements.

Given a dictionary:

dct = {
	'a': 12,
	'b': 34,
	'c': 56
}

Get all its elements in the following form:

['a', 12, 'b', 34, 'c', 56]
