Python is a high-level, interpreted programming language known for its readability and simplicity. It supports multiple paradigms including procedural, object-oriented, and functional programming.
Guido van Rossum created Python, with the first version released in 1991. It was named after the British comedy series Monty Python.
Python features dynamic typing, automatic memory management, extensive standard library, and cross-platform compatibility. It emphasizes code readability with significant whitespace.
Save the code in a file with .py extension, then run python filename.py in the terminal. Use python3 if Python 2 is also installed.
REPL stands for Read-Eval-Print Loop, an interactive shell for executing Python code line-by-line. Access it by typing python in the terminal.
Variables are names that reference objects storing data. They are created on first assignment, like x = 5, and are dynamically typed.
Dynamic typing means variable types are determined at runtime, not compile-time. A variable can hold different types sequentially, e.g., x = 5; x = 'hello'.
Basic immutable types include int (integers), float (floating-point), str (strings), and bool (True/False). Mutable types include lists and dictionaries.
None is a singleton object representing the absence of a value, often used as a default return for functions without explicit returns.
Use functions like int(), float(), str(), or bool(). For example, int('42') converts string '42' to integer 42.
They include + (addition), - (subtraction), * (multiplication), / (division), // (floor division), % (modulo), and ** (exponentiation).
Comparison operators like ==, !=, >, <, >=, <= return a boolean value: True or False.

Programming is one of the most valuable and versatile skills in the modern economy. Whether you're a bootcamp graduate solidifying fundamentals, a CS student preparing for exams, or a developer prepping for FAANG interviews, these flashcards help you master the concepts that separate junior developers from senior engineers — algorithms, system design, and software architecture.
After reviewing an algorithm or data structure card, implement it from scratch in your preferred language to build muscle memory.
For every algorithm, know its Big O time and space complexity — this is the most commonly tested concept in technical interviews.
Focus on recognizing problem patterns (sliding window, two pointers, dynamic programming) rather than memorizing individual solutions.
Yes, our programming decks cover algorithms, data structures, and system design concepts frequently tested in technical interviews at top companies.
Our flashcards focus on language-agnostic concepts, but examples reference popular languages like Python, JavaScript, Java, and C++.
We offer decks from introductory programming concepts to advanced topics like distributed systems and compiler design.
Our flashcards cover concepts in Python, JavaScript, Java, C++, Go, and more, with language-agnostic cards on algorithms and design patterns.
Yes, we have extensive coverage of arrays, linked lists, trees, graphs, sorting algorithms, dynamic programming, and complexity analysis.
Absolutely — our decks focus on the algorithmic patterns, system design concepts, and problem-solving frameworks tested at top tech companies.
