Made for teaching programming.

Everything TurboByte does for a programming course, and what is coming next, each marked as it really is.

Step through, one sentence at a time.

A debugger for beginners narrates every step, in English or Hebrew.

Step 1 of 5

def average(numbers):    if not numbers:        return 0    return sum(numbers) / len(numbers) print(average([90, 72, 85]))

The program calls average with [90, 72, 85].

When a program breaks, a plain-language card says what happened, and where.

def average(numbers):    return sum(numbers) / len(numbers) print(average([]))

ZeroDivisionError: division by zero

Dividing by zeroOn line 2, len(numbers) is 0 for an empty list, and Python cannot divide by 0.

Owners, instructors and TAs, with deadlines, late work and extensions.
