Write Python. Run Python.

This is a working Python interpreter, not a quiz about Python. Variables, loops, functions, dictionaries, exceptions, files — all of it executes, and when you make a mistake you get the same error message CPython would give you.

# this runs, right here
for i in range(1, 4):
print(i, "squared is", i*i)>>> 1 squared is 1
>>> 2 squared is 4
>>> 3 squared is 9
