The task: use the diagnostics

This program should flash the LED three times, beeping each time, and then print flashed 3 times. It has a syntax error, a runtime error and a logic error. Use the squiggle, the error message and Debug to find and fix all three.

# the two lines every program starts with: the commands, then the robot
from bugbot import *
connect()

flashes = 0
for i in range(3)
    led("blue")
    tone(660, 0.1)
    wait(0.2)
    led("off")
    flashes = 1
print("flashed", flashs, "times")

Plan your program here, then type it in and press Run.

Do it on the robot

The simulator checks it and tells you when it passes. Nothing to install, no account.
