Study Notes
Introduction to Python
- Python is a high-level, general-purpose programming language.
- It's known for its clear syntax, making it relatively easy to learn and read.
- Python is dynamically typed, meaning you don't need to explicitly declare variable types.
- It supports multiple programming paradigms, including object-oriented, procedural, and functional programming.
- Python has a large and active community, providing extensive libraries and resources.
Core Concepts
- Variables: Used to store data. Variables do not have a fixed type.
- Data Types: Includes integers, floating-point numbers, strings, Booleans, lists, tuples, dictionaries, and sets.
- Operators: Used to perform operations on data (arithmetic, comparison, logical, bitwise).
- Control Flow: Allows conditional execution (if/else statements) and looping (for/while loops).
- Functions: Blocks of code that perform specific tasks. Functions can accept and return values. Can be defined within other functions (nested).
- Modules: Bundles of code containing related functions or classes. Modules can be imported into other programs. Many standard modules are available in the Python library.
Data Structures
- Lists: Ordered, mutable sequences of items. Can contain items of different data types. Accessed using indexing.
- Tuples: Ordered, immutable sequences of items. Similar to lists, but cannot be modified after creation.
- Dictionaries: Unordered collections of key-value pairs. Keys are unique and used to access values.
- Sets: Unordered collections of unique items.
Input and Output
- Input: Python allows reading data from various sources (keyboard, files).
- Output: Python provides ways to display information to the user (console).
Libraries and Packages
- Python has extensive third-party libraries covering various domains.
- NumPy: Fundamental package for numerical computation.
- Pandas: For data manipulation and analysis.
- Matplotlib: For creating static, interactive, and animated visualizations.
- Scikit-learn: A machine learning library.
Object-Oriented Programming (OOP)
- Classes: Blueprints for creating objects. Classes define attributes (data) and methods (actions).
- Objects: Instances of a class. Hold the data described by the class.
- Inheritance: Creating new classes based on existing ones, inheriting attributes and methods.
- Encapsulation: Bundling data and methods that operate on that data within a class, hiding internal details.
- Polymorphism: Objects of different classes can respond to the same method call in different ways.
Exception Handling
- try...except blocks: Used to handle potential errors during program execution.
- Errors (exceptions) can be caught using
tryandexceptstatements. This allows robust programs.
File Handling
- Reading and writing files: Python provides ways to open, read, and write files.
Programming Style
- Indentation: Python uses indentation to define code blocks, rather than curly braces.
Working with Strings
- String manipulation: Various methods exist for working with strings – searching, replacing, splitting, etc.
-
Regular expressions: Python's
remodule allows complex string manipulations.
Common Operations
- Iteration: Python supports loops for iterating over data structures.
-
Conditional statements: Using
if,elif, andelseto control program flow based on conditions. -
Loops: Implementing
forloops andwhileloops.
Functions
- Defining functions: Creating custom functions to encapsulate code logic.
- Function arguments: Passing data to functions.
Modules
-
Import statements: Using
importto make modules available during execution. - Using modules: Accessing the functions and classes defined in imported modules.
