Questions
Which Python is this?
MicroPython 1.29, a fast implementation of Python 3 with the core language, f-strings, classes, generators, exceptions and modules such as math, json, re, random, collections and ulab (a NumPy subset). Some standard-library modules and third-party packages are not available.
How does input() work?
Type the values your program reads into the Input box, one per line, before pressing Run.
What about infinite loops?
Each run has a time limit and a Stop button; the interpreter runs in a separate worker and is discarded afterwards.
Is my code uploaded?
No. It runs in your browser and drafts are saved only in this browser. Share links keep the code in the part of the URL after #, which browsers never send to a server.
