Python Data Types#

Python has various data types, each with its own unique characteristics and purposes.
I will explain the main data types.

1. Numeric Types#

• Integer (int): An integer data type. It includes both positive and negative numbers and has no size limit.

a = 10
b = -5

• Floating Point (float): A floating-point data type that includes decimal points.

c = 3.14
d = -0.5

• Complex Numbers (complex): A complex number data type with a real part and an imaginary part.
  The imaginary part is represented using j.

e = 1 + 2j

2. Sequence Types#

• String (str): A collection of characters enclosed in single quotes (’) or double quotes (").

f = "Hello, World!"

• List (list): A mutable sequence type that stores multiple values in order.
  It is defined using square brackets ([ ]) and can include different data types.

g = [1, 2, 3, 'a', 'b', 'c']

• Tuple (tuple): Similar to a list but immutable.
  It is defined using parentheses (( )).

h = (1, 2, 3, 'a', 'b', 'c')

3. Set Types#

• Set (set): A collection of unique elements.
  It is unordered and defined using curly braces ({ }).

i = {1, 2, 3, 4, 5}

• frozenset: An immutable set.
  It is created using the frozenset() function.

j = frozenset([1, 2, 3, 4, 5])

4. Mapping Types#

• Dictionary (dict): A collection of key-value pairs.
  It is defined using curly braces ({ }) and the keys must be unique.

k = {'name': 'Alice', 'age': 25}

5. Other Types#

• Boolean (bool): A type that represents True and False.

l = True
m = False

• None: A type that represents the absence of a value.

n = None
