LEVEL 2

1 – Decimal numbers and other tools

• 1) Origami

epaisseurpapier = 0.110
epaisseurpapier_en_centimètre = 0.011

for plis in range(15):
    epaisseurpapier_en_centimètre = epaisseurpapier_en_centimètre * 2
    epaisseur_final = epaisseurpapier_en_centimètre
    plis += 1

print(epaisseur_final)

• 2) Distance conversions

nblieux = float(input())

print(nblieux / 0.707)

• 3) Price comparison

nb_legumes_vente = int(input())

for legumes in range(nb_legumes_vente):
    poids = float(input())
    age = float(input())
    prix = float(input())
    prix_kg = prix / poids
    print(prix_kg)

• 4) Average marks

nb_notes = int(input())
total = 0
for i in range(nb_notes):
    note = int(input())
    total += note
moyenne = total / nb_notes
print(moyenne)

A – Make roundings (lower and upper)

• A - 1) Population increase

population_actuelle_ville = int(input())
croissance_population = float(input())

nouvelle_population = int(population_actuelle_ville * (1 + croissance_population / 100))

print(nouvelle_population)

• A - 2) Construction of houses

from math import *

quantite_ciment_kg = float(input())
nb_sacs_ciment = int(ceil(quantite_ciment_kg / 60))
cout_tt = nb_sacs_ciment * 45
print(cout_tt)

B – Make roundings (to nearest)

• B - 1) Stormy evening

temps = float(input())

distance = temps * 340.29

distance_km = round(distance / 1000)
print(distance_km)

• B - 2) Tax increase

taxe_actuelle = float(input())
nouvelle_taxe = float(input())
prix_actuel = float(input())

prix_nouvelle_taxe = prix_actuel * (1 + nouvelle_taxe / 100) / (1 + taxe_actuelle / 100)

print(round(prix_nouvelle_taxe, 2))

C – Basic Arithmetic

• C - 1) Purchase of books

somme_d_argent = int(input())
prix_d_un_livre = int(input())

nb_livre_achetable = somme_d_argent // prix_d_un_livre

print(nb_livre_achetable)

• C - 2) A good harvest

nbPersonnes = int(input())
nbFruits = int(input())

if nbFruits % nbPersonnes == 0:
    print("oui")
else:
    print("non")

• C - 3) The wheel of fortune

2 – Discovery of the paintings

3 – Character strings

4 – Functions

5 – Programming on your computer
