Study Notes

Python: Basics, Data Types, Functions

Python is a versatile and popular programming language known for its simplicity and readability. In this article, we will dive into the basic concepts of Python, including data types and functions.

Python Basics

Python is an interpreted, high-level programming language. It is designed to be both easy to read and write, with a focus on code readability. Python's syntax is consistent and straightforward, making it a great choice for beginners.

Python Data Types

Python has several built-in data types that allow you to store and manipulate data. These data types include:

String (str): Represents a sequence of characters. Strings are enclosed in single or double quotes.
Numeric types: int, float, and complex. These data types are used for numerical operations.
Boolean (bool): Represents either True or False.
Sequence types: list, tuple, and range. These data types are used to store collections of items.
Mapping type: dict. This data type is used to store data in key-value pairs.
Set types: set and frozenset. These data types are used to store collections of unique items.
Binary types: bytes, bytearray, and memoryview. These data types are used for binary data operations.
None type: NoneType. This data type represents the absence of any value.

To determine the data type of a variable, you can use the type() function. For example, type(5) will return <class 'int'>, indicating that the variable is of type int.

Python Functions

Functions in Python are blocks of code that perform specific tasks. They allow you to reuse code and make your program more modular and maintainable. Python supports two types of functions:

Defined functions: These are functions that you define yourself. They are created using the def keyword followed by the function name and the code block that defines the function's behavior.
Built-in functions: Python provides a rich set of built-in functions that perform various operations. Examples include print(), input(), len(), range(), and type().

To call a function, you use its name followed by parentheses containing any necessary arguments. For example, print("Hello, World!") will output the string "Hello, World!".

Python's functions can be defined in various ways, such as using lambda expressions or decorators. These functions can also take different types of parameters, including positional parameters, keyword parameters, and variable-length arguments.

In conclusion, Python is a powerful and flexible programming language that provides a wide range of data types and functions to help you develop efficient and maintainable code. By understanding the basics of Python, you can start building your own applications and explore the full potential of this versatile language.
