Python Data Types
#

Python has a wide variety of built-in data types. This section provides an overview of the most common ones.

Numeric Types
#

Python has three distinct numeric types: integers, floating-point numbers, and complex numbers.

# Integers
x = 10
print(type(x))  # 

# Floating-point numbers
y = 3.14
print(type(y))  # 

# Complex numbers
z = 1 + 2j
print(type(z))  #

Sequence Types
#

These represent ordered collections of items.

  • Strings (str): Immutable sequences of Unicode characters.
  • Lists (list): Mutable sequences, typically used to store collections of homogeneous items.
  • Tuples (tuple): Immutable sequences, used to store collections of heterogeneous items.
# String
my_string = "Hello, World!"
print(my_string[7:])  # "World!"

# List
my_list = [1, 2, 3, "apple"]
my_list.append(4)
print(my_list)  # [1, 2, 3, 'apple', 4]

# Tuple
my_tuple = (1, "a", True)
print(my_tuple[1])  # "a"

Mapping Type
#

The dictionary (dict) is a mutable, unordered collection of key-value pairs.

my_dict = {"name": "Alice", "age": 30}
print(my_dict["name"])  # "Alice"
my_dict["city"] = "New York"
print(my_dict)  # {'name': 'Alice', 'age': 30, 'city': 'New York'}

Set Types
#

A set is an unordered collection of unique items.

  • Set (set): Mutable, unordered collection of unique elements.
  • Frozenset (frozenset): Immutable version of a set.
my_set = {1, 2, 3, 3, 4}
print(my_set)  # {1, 2, 3, 4}
my_set.add(5)
print(my_set)  # {1, 2, 3, 4, 5}

Boolean Type
#

The boolean type (bool) has two possible values: True and False.

is_active = True
print(is_active)

print(10 > 5)  # True
