Chapter 7 / Level 2: Function arguments

Teaching Objective:

• Student learns how to use arguments with functions
• Leans how to package loops inside a function
• Understands how a custom function can be used dynamically throughout a level

Guide

In order to complete the level, the student must water all the crops writing no more than 13 lines of code. To do this, they need to create a custom function and add a for loop that you can manipulate using arguments.

def water_crops(count):
	for x in range(count):
		player.move_forward(2)
		player.turn_left()
		player.water()
		player.turn_right()

Use this function three times throughout the level each time entering a different value to the argument count . Do it corresponding to the number of X marks in a row, like this: water_crops(4) .

By using this function to it’s fullest you will be able to complete the level writing no more than 13 lines of code.

Code Solution

import player

def water_crops(count):
    for x in range(count):
		player.move_forward(2)
		player.turn_left()
		player.water()
		player.turn_right()
player.turn_left()
water_crops(4)
player.turn_right()
water_crops(2)
player.turn_right()
water_crops(3)
