Your code will probably need to look for different markers depending on the zone your robot starts in. Whilst you could have different files for each zone, there's also a property on the robot object for this.

Python will be equal to the start zone of the robot and will have a value from 0 to 3.

Here's an example:

if == 3:
    print("Do something!")
    print("Do something else!")


You can find the zone block in the Movement section.
