Answer to Question #309496 in Python for Manish

Question

Maximum Number of Books

There are multiple (T) bookstores in the area.Each shopkeeper has a list of B integers that represents the cost of each book.You have different pocket money(P) for each bookstore.Write a program to calculate the maximum number of books you can buy in each store with the corresponding pocket money.

Explanation

Given P = 600 and B = [120, 140, 110, 180, 120, 110] with a pocket money of 600, we can buy the books at index 0,1,2,4,5 , whose sum is 120+140+110+120+110 is equal to P.

Given P = 300 and B = [120 110 1300 130] with a pocket money of 300, we can buy the books at index 0,1 whose sum is 120 + 110 and is less than P.

Given P = 100 and B = [220 1000 500 2000] with pocket money of 100, we can't buy any book. So the output should be Retry.

def lib_pay(P, B):
    k = 0
    list1 = []
    for i, j in enumerate(B):
        if j > P:
            print('retry')
            break
        else:
            list1.append(i)
            k = k + j
            if k < P:
                break
        
    print(list1)
