Modules and several files

Split a program into files and import them; what the standard library offers without installing anything.

main.py

from geometry import area
import math

print(area(3, 4))
print(round(math.pi, 3), math.sqrt(16))

geometry.py

def area(width, height):
    return width * height

Output

Two files: main.py (the entry, run by Run) and geometry.py next to it.

A file geometry.py is imported as geometry; a folder utils/ with utils/text.py is imported as utils.text.
The whole standard library is available (math, random, datetime, collections, itertools, json, re, …).
Third-party packages (pip install) are not available: runs have no network and nothing is installed during a run.
