Tutorial Moodle VPL Rock-Paper-Scissors -- Python
This tutorial builds on the first one in the series, which should be done first, as the present tutorial skips some steps. In this tutorial we setup a VPL activity that will allow students to submit Python programs that play the game of Rock-Paper-Scissors.
- Moodle Version 2.7 + (Build: 20140529)
- VPL Version 3.0.1
- For details on how Moodle and VPL were installed, go to this page.
Here are the main settings for the new VPL activity:
Tips & Tricks
To generate the vpl_evaluate.cases file, I found that running the program first and capturing its output, and then using this text to generate the input and output sections of the vpl_evaluate.cases file is quick and simple.
- In the Administration box, click on Test activity, then Edit, and enter the solution program below:
user = 0
while abs( computer - user ) < 3:
play = input( "> " ).upper().strip()
if len( play ) != 2:
cPick = play
uPick = play
if uPick == cPick:
print( "Tie" )
pair = cPick + uPick
if pair in [ "PR", "SP", "RS" ]:
computer += 1
print( "Player 1 wins" )
user += 1
print( "Player 2 wins" )
if computer > user:
print( "winner: Player 1 (%d to %d)" % ( computer, user ) )
print( "winner: Player 2 (%d to %d)" % ( user, computer ) )
- Save, and Evaluate
- Verify that the program runs and passes the two tests.
