Tester.py

from critter import Critter

# A ForgetfulCritter can't remember it's history.

class ForgetfulCritter$($Critter$)$ :

$...$

def main$()$ :

dopey $=$ ForgetfulCritter$()$

dopey.addHistory$("$eat$")$;

print$($dopey$.$getHistory$())$

print$("$Expected: $[?]")$

dopey.move$(10)$

print$($dopey$.$getHistory$())$
