Study Notes
Introduction to Python
- Python is a high-level, general-purpose programming language.
- It's known for its clear syntax, readability, and large standard library.
- Python supports multiple programming paradigms, including object-oriented, imperative, and functional programming styles.
- It's widely used in various domains like web development, data science, machine learning, scripting, and automation.
Key Features
- Interpreted Language: Python code is executed line by line by an interpreter, eliminating the need for compilation.
- Dynamically Typed: Variables do not need explicit type declarations. Python infers the type based on the assigned value.
- High-Level Language: Python abstracts away low-level details, allowing programmers to focus on the logic of the program.
- Extensive Libraries and Frameworks: Python boasts a rich ecosystem of libraries and frameworks, providing pre-built functionalities for tasks like data analysis, web development, and machine learning.
- Large Community and Support: A vast community of developers provides abundant documentation, tutorials, and support resources to help with issues and learning the language.
- Cross-Platform Compatibility: Python code can run on various operating systems (Windows, macOS, Linux) with minimal or no modifications.
Basic Data Types
- Integers: Whole numbers (e.g., 10, -5, 0).
- Floating-Point Numbers: Numbers with decimal points (e.g., 3.14, -2.5).
- Strings: Sequences of characters enclosed in quotes (e.g., "Hello", 'Python').
- Booleans: Represent truth values (True or False).
- Lists: Ordered collections of items (e.g., [1, 2, "a"]).
- Tuples: Ordered, immutable collections of items (e.g., (1, 2, "a")).
- Dictionaries: Key-value pairs (e.g., {"name": "Alice", "age": 30}).
- Sets: Unordered collections of unique items (e.g., {1, 2, 3}).
Control Flow
- Conditional Statements (if-elif-else): Execute different blocks of code based on conditions.
- Loops (for and while): Iterate over sequences of code multiple times.
- Break and Continue: Used to control the flow of loops and exit them prematurely or skip iterations.
Functions
- Defining Functions: Creating reusable blocks of code that perform specific tasks.
- Arguments and Parameters: Passing data to functions for processing.
- Return Values: Sending data out of functions.
Modules and Packages
- Modules: Sets of functions and classes grouped together for related tasks.
- Packages: Collections of modules that often address a specific software domain, grouped into hierarchical structures.
Object-Oriented Programming (OOP)
- Classes: Blueprints for creating objects, defining attributes (data) and methods (functions).
- Objects: Instances of classes that hold specific data values.
- Inheritance: Creating new classes based on existing ones, inheriting their attributes and methods.
- Encapsulation: Bundling data and methods that operate on that data within a class.
- Polymorphism: Using methods with the same name in different classes in a hierarchy.
Important Libraries
- NumPy: Numerical computing library for array operations and mathematical functions.
- Pandas: Data manipulation and analysis library for working with dataframes.
- Matplotlib: Plotting library for visualizing data.
- Scikit-learn: Machine learning library for various algorithms.
- Requests: HTTP library for making HTTP requests.
- Flask/Django: Web frameworks for creating web applications.
Variables
- Variables are used to store data.
- They are assigned values using the
=operator. - Variables can hold different data types (integers, strings, floats, etc.).
Data Structures
- Lists: Ordered, mutable sequences of items.
- Tuples: Ordered, immutable sequences of items.
- Dictionaries: Collections of key-value pairs.
- Sets: Collections of unique items.
Input/Output
print(): Displays output to the console.input(): Reads input from the user.
