SharafatKarim / best_value.py
Created November 16, 2022 04:05
A simple program to help to find the best item! Suppose first column refers to the price, second one amount and the third refers to validity. Validity (third column) is an optional thing and may not be present. You have to find the best value (Amount divided by price) out of all of them. Then sort them.
Price = [9,13,7,18,10,76,10,76,33,63,113,19,49,23,49,23,19,31,51,42,66,29,30,36,116,91]
Value = [100,100,150,200,250,300,250,300,300,300,300,300,400,400,400,400,500,512,512,512,512,512,1000,1000,1000,1000]
Validity = []
Price = []
Value = []
def Validity_to_store():
print("Do you also want to store validity data? ")
k = input()[0]
