Bonjour
# This program asks for your name and uses
# it in an output message.
# Run the program here by typing "Ctrl R"

Exemple de boucle
# This program uses a "for" loop to calculate
# the squares and cubes of the first 5 numbers
# 0,1,2,3,4
# Note: Python starts counting at 0
for index in range(5):
••square = index**2

# Use random numbers to simulate a coin flip
