30 Python Concepts

Variables: Containers for storing data values.

Data Types: The different categories of data, like integers, strings, floats, lists, and more.

Strings: Sequences of characters, often used for text manipulation.

Lists: Ordered collections of items, which can be of different data types.

Tuples: Similar to lists, but immutable (cannot be changed after creation).

Dictionaries: Collections of key-value pairs, allowing efficient data retrieval.

Sets: Unordered collections of unique elements.

Conditional Statements: Structures like if, elif, and else for making decisions in code.

Loops: Constructs like for and while to repeatedly execute code blocks.

Functions: Blocks of reusable code, allowing modularity in programs.

Modules: Files containing related functions, classes, and variables.

Classes and Objects: Blueprint for creating objects with attributes and methods.

Inheritance: Mechanism for creating a new class from an existing one, inheriting attributes and methods.

Polymorphism: Ability to use the same interface for different data types or objects.

Exception Handling: Dealing with errors gracefully to prevent program crashes.

File Handling: Reading from and writing to files on the system.

Modules and Libraries: Pre-built code to extend Python's capabilities.

Virtual Environments: Isolated spaces to manage dependencies for different projects.

Lambda Functions: Small, anonymous functions defined using the lambda keyword.

List Comprehensions: Concise way to create lists using a single line of code.

Generators: Functions that produce values one at a time, conserving memory.

Decorators: Functions that modify the behavior of other functions.

Recursion: A function calling itself, often used to solve complex problems.

Mutable vs. Immutable: Understanding data types that can or cannot be changed after creation.

Global vs. Local Scope: Differentiating between variables accessible throughout the program or just within specific functions.

Namespaces: Containers for holding identifiers and their corresponding objects.

List Slicing: Extracting portions of lists using index ranges.

Object-Oriented Programming (OOP): Programming paradigm focusing on objects and classes.

Regular Expressions: Patterns used for searching and manipulating text.

Pythonic: Writing code in a way that is idiomatic and follows Python conventions.
