Your mini-project to-do list

0 of 4 completed

Complete these activities in the mini-project editor above. After each change, select Run my code to check your program’s output or drawing.

Level 1: Change every side from 100 to 60.Level 2: Change the distances to turn the square into a rectangle.Level 3: Invent your own path using forward() and right().

Save your finished mini project

Select Download my work and save the file as week_5_turtle_square.py. The .py ending tells us that the file contains Python code. Keep this file as a copy of your finished program.

Debugging detective

In your mini-project code: Change one turn from 90 to 80. Observe the gap, then repair the angle. Select Run my code after each change to check your program’s output or drawing.
