Study Notes
Introduction to Python
- Python is a high-level, interpreted programming language.
- It was created in the late 1980s by Guido van Rossum.
- Python is known for its simplicity, readability, and ease of use.
Features of Python
- Easy to learn: Python has a simple syntax and is relatively easy to learn, making it a great language for beginners.
- High-level language: Python is a high-level language, meaning it abstracts away many low-level details, allowing developers to focus on the logic of the program.
- Interpreted language: Python code is interpreted rather than compiled, making it easy to write and test code.
- Object-oriented: Python is an object-oriented language, which means it organizes code into objects that contain data and functions that operate on that data.
- Large standard library: Python has a large and comprehensive standard library that includes modules for various tasks, such as file I/O, networking, and data structures.
Basic Syntax
- Indentation: Python uses indentation (spaces or tabs) to define block-level structure.
-
Variables: Variables are assigned using the
=
operator. -
Data types: Python has several built-in data types, including:
- Integers (int): whole numbers, e.g. 1, 2, 3
- Floating-point numbers (float): decimal numbers, e.g. 3.14, -0.5
- Strings (str): sequences of characters, e.g. "hello", 'hello'
- Boolean (bool): true or false values
- List (list): ordered collections of items, e.g. [1, 2, 3], ["a", "b", "c"]
- Operators: Python has various operators for performing arithmetic, comparison, logical, and assignment operations.
-
Control structures: Python has several control structures, including:
- If-else statements: used for conditional execution
- For loops: used for iterating over sequences
- While loops: used for repeated execution
Advanced Topics
- Modules: Python has a vast collection of modules that can be imported to perform specific tasks.
- Functions: Functions are reusable blocks of code that take arguments and return values.
- Classes: Classes are used to define custom data types and behaviors.
- Exception handling: Python has a built-in exception handling system that allows developers to handle errors and exceptions.
Applications of Python
- Web development: Python is used in web development frameworks such as Django and Flask.
- Data analysis and science: Python is widely used in data analysis, machine learning, and scientific computing.
- Automation: Python is used for automating tasks, such as data processing, file management, and system administration.
- Artificial intelligence and machine learning: Python is used in AI and ML applications, including natural language processing, computer vision, and robotics.
