Building

You can use variables to write programs that build

mazes!

You can draw the map and play with your own mazes.

The symbols (to be separated by spaces):

o               un mur
.               une case vide
↑ → ↓ ←         la fourmi
x               la porte
r               un caillou
R               un caillou aléatoire
w               une toile
W               une toile aléatoire

from laby.global_fr import *
carte ="""
o o o o o o o o
o . . . r o w x
o . o o . o . o
o ↑ . . . . . o
o o o o o o o o
"""
Laby(carte = carte)

debut()

A maze can be created from a character string.

In Python, strings can be stored in variables, added, multiplied…

c = ". "
print(c)

. 

deux_c = c + c
print(deux_c)

. . 

ligne = c * 10
print(ligne)

. . . . . . . . . . 

To put two lines in a row, you have to separate them by the carriage return

character \n

deux_lignes = ligne + "\n" + ligne
print(deux_lignes)

. . . . . . . . . . 
. . . . . . . . . . 

What does the following program do?

murs = "o " * 12 + "\n"
ligne = "o " + ". " * 10 + "o \n"
carte = murs + ligne * 10 + murs
print(carte)

o o o o o o o o o o o o 
o . . . . . . . . . . o 
o . . . . . . . . . . o 
o . . . . . . . . . . o 
o . . . . . . . . . . o 
o . . . . . . . . . . o 
o . . . . . . . . . . o 
o . . . . . . . . . . o 
o . . . . . . . . . . o 
o . . . . . . . . . . o 
o . . . . . . . . . . o 
o o o o o o o o o o o o 

This map is incorrect because it does not contain an ant or a door.

Copy the program and modify it to add the ant and the door. Then launch the

“real” maze with the command Laby(carte = carte)

You can use all the previous concepts (loops, if statements, variables, functions,

etc.) to build mazes and not just solve them.

• Can you make a zigzag?

• A spiral?

• A checkerboard?

• A shape of your choice?
