What kind of language is Python?

0:15
Python is a high-level, interpreted, dynamically typed, garbage-collected, multi-paradigm programming language. It supports object-oriented, functional, and procedural styles. Python emphasizes code readability and uses indentation to define code blocks instead of braces.
docs.python.org

What does it mean that Python is dynamically typed?

0:14
Dynamically typed means that variable types are checked at runtime, not at compile time. A variable is just a name bound to an object, and the same name can be rebound to objects of different types during execution. Type errors are raised only when the offending code actually runs.
docs.python.org

What does it mean that Python is strongly typed?

0:15
Strongly typed means Python does not perform implicit type coercions between unrelated types. For example, adding a string and an integer raises a TypeError instead of silently converting one to the other. Type conversions must be explicit using functions like int, str, or float.
docs.python.org

What is CPython?

0:14
CPython is the reference implementation of Python, written in C. It is the most widely used Python interpreter and the one distributed at python.org. Other implementations include PyPy with its just-in-time compiler, Jython on the JVM, and IronPython on .NET.
docs.python.org

What is the latest stable version of Python as of 2026?

0:16
As of 2026, the latest stable Python release is 3.14, with 3.14.3 being the current maintenance release. Python 3.13 is still widely used and supported. Python 3.15 is in alpha with a full release planned for October 2026.

What is PEP 8?

0:16
PEP 8 is the official style guide for Python code. It covers naming conventions, indentation, line length, imports, whitespace, and other formatting rules. Following PEP 8 makes code consistent and readable across the Python ecosystem. Tools like ruff, black, and flake8 enforce it automatically.
peps.python.org

What is the Zen of Python?

0:16
The Zen of Python is a collection of nineteen guiding principles for writing Python code, authored by Tim Peters and codified in PEP 20. You can read it by typing import this in any Python interpreter. Famous lines include "Beautiful is better than ugly" and "There should be one obvious way to do it."
peps.python.org

How is Python code executed?

0:15
Python source code is first compiled into bytecode by the interpreter, which is then executed by the Python virtual machine. The bytecode is cached in pycache directories as pyc files to speed up subsequent imports. This makes Python a hybrid compiled and interpreted language.
docs.python.org

What is the difference between an interpreter and a compiler?

0:17
A compiler translates the entire source code into machine code before execution, producing a standalone executable. An interpreter reads and executes source code line by line at runtime. Python uses a hybrid model: it compiles to bytecode first, then interprets the bytecode in a virtual machine.
docs.python.org

What is the Python Standard Library?

0:16
The Python Standard Library is a large collection of modules included with every Python installation. It provides functionality for file I/O, networking, data serialization, threading, math, regular expressions, and much more. Its breadth is often summarized as "batteries included." ---
