Correction:

x = random.randint(0,Largeur)
y = random.randint(0,Hauteur)

Exercice 2 :

Modifier le programme pour que la taille du cercle varie entre 10 et 30 de manière aléatoire.

Correction:

r = random.randint(20,30)

Exercice 3 :

Modifier le programme pour que la couleur soit rouge ou bleu ou orange de manière aléatoire.

Correction:

«  » » Dessine un cercle de centre (x,y) et de rayon r «  » »
couleurs = [‘red’, ‘blue’, ‘orange’]
x = random.randint(0,Largeur)
y = random.randint(0,Hauteur)
r = random.randint(20,30)
c = random.randint(0,len(couleurs)-1)
Canevas.create_oval(x-r, y-r, x+r, y+r, outline=couleurs[c], fill=couleurs[c])
