📖 How to Use Python Simulator
Type or paste Python code. Supports print(), variables, if/elif/else, for/while loops, def functions, class definitions, lists, dicts, f-strings, and comprehensions.
The simulator transpiles Python syntax to JavaScript and executes it in your browser. print() output appears on the right side.
Use the example buttons to see working code: Hello World, Loops & Comprehensions, Functions & Recursion, Dictionaries, and OOP Classes.
This is a browser-based simulator supporting core Python syntax. External libraries (numpy, pandas) are not available — use it to learn Python logic and algorithms.
Python Syntax
print(), if/elif/else, for/while, def, class, lambda, try/except basics.
Data Structures
Lists, tuples, dicts with .append(), .get(), .items(), sorted(), enumerate().
F-strings
f"Hello {name}" string interpolation with expressions inside curly braces.
OOP Classes
class, __init__, self, methods, inheritance with super(), __str__.
List Comprehensions
[x**2 for x in range(10) if x%2==0] — fully supported.
Built-in Functions
len(), range(), sum(), max(), min(), sorted(), enumerate(), zip(), map(), filter().
