Explore the core Python compound data types such as lists, tuples, dictionaries, and sets. Learn their characteristics, how they handle different data types, and discover practical examples to build your foundational programming skills.
Compound data types
Compound data types are data types that can hold different types of values together. They are basically composed of other data types, such as lists, for instance.
Lists
Lists (list): Ordered and mutable collections of items. The elements inside can be of different data types.
topics_covered = ["Variables", "Loops", "Functions", "Data Structures"]
print("Topics covered:", topics_covered)
List data type in Python
Let’s define another list with various data types stored in it.
different_types_list = [False, 100.5, "Hello!"]
print("A list containing various types: ", different_types_list)

Tuples
Tuples (tuple): Ordered and immutable collections of items. The elements inside can be of different data types.
days_of_the_week = ("Monday", "Tuesday", "Wednesday", "Thursday", "Friday")
print("Days of the week:", days_of_the_week)
Tuple data type in Python
Let’s define another tuple with various data types stored in it.
different_types_tuple = ("Strings", 20, 15.5, True, None)
print("A tuple containing various types: ", different_types_tuple)

Dictionaries
Dictionaries (dict): Unordered collections where each item is represented as a key-value pair. All keys are unique.
instructors_courses = {"Ash": "Python Basics", "X12": "Advanced Python", "Is": "Data Science / ML with Python"}
print("Instructors and Courses:", instructors_courses)

Sets
Sets (set): Unordered collections of unique elements.
set_variable = {1, 2, 3, "How many data types are there?"}
print("Our Set:", set_variable)
