Variable And Data Types: a container for a value. Behaves
as the value that it contains
Primitive (Fundamental) Data Types: represent simple values.
These data types are the most basic and essential units used to
store and manipulate information in a program. They translate
directly into low-level machine code.
- String (str): Represents sequences of characters. Should be enclosed in
quotes.
Example: "Hello, Python!"
Strings are used for text manipulation and representation.
- Integer(int): Represents whole numbers without decimals.
Example: 31
- Float (float): Represents numbers with decimals.
Example: 3.14
Integers and floats are essential for numerical calculations.
- Boolean (bool): Represents either True or False.
Booleans are employed in logical operations and decision-making.
Non-Primitive (Composite) Data Types: are structures that
can hold multiple values and are composed of other data types,
including both primitive and other composite types. Unlike
primitive data types, non-primitive types allow for more complex
and structured representations of data.
- List (list): Represents an ordered and mutable (có thể thay đổi) collection of
values.
Example: fruits = ["apple", "banana", "cherry"]
Lists: Useful when you need a collection that can be altered during the
program's execution, such as maintaining a list of items that may
change over time.
- Tuple (tuple): Represents an ordered and immutable collection of values.
