Data Types in Python – Part 2

In Part 1, we learned about numeric, string, and Boolean data types. Now let's look at Python's collection data types.

1. List (list)

A list is used to store multiple values in one variable.

fruits = ["apple", "banana", "mango"]

print(fruits)

Output:

['apple', 'banana', 'mango']

Lists are ordered and changeable.

2. Tuple (tuple)

A tuple is also used to store multiple values, but its values cannot be changed after creation.

colors = ("red", "green", "blue")

print(colors)

Output:

('red', 'green', 'blue')

3. Set (set)

A set stores multiple values and does not allow duplicate values.

numbers = {1, 2, 3, 3}

print(numbers)

Output:

{1, 2, 3}

4. Dictionary (dict)

A dictionary stores data using key-value pairs.

student = {
    "name": "Vishnu",
    "age": 21
}

print(student)

Output:

{'name': 'Vishnu', 'age': 21}

5. None (NoneType)

None represents no value.

result = None

print(result)

Output:

None
