Practicing the studied material on working with dictionaries in Python

Given a dictionary:

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

Find the sum of the squares of the elements of this dictionary.

The following dictionaries are given:

dct1 = {
	'1': 12,
	'2': 24,
	'3': 36
}

dct2 = {
	'a': '3',
	'b': '6',
	'c': '9'
}

Add up the values of each dictionary. Then subtract the second sum from the first.

Given a dictionary:

dct = {
	1: '4',
	2: '5',
	3: '6'
}

Convert all its values to strings.

Given a dictionary:

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

Add the elements of this dictionary as strings:

'123'

Given a dictionary:

dct = {
	'a': 7,
	'b': 6,
	'c': 5
}

Add the elements of this dictionary as strings:

'5/6/7'

Given a dictionary with a date:

dct = {
	'y': 2025,
	'm': 12,
	'd': 31
}

Add the elements of this dictionary to form the following date:

'2025-12-31'
