Question

Write a python program that repeatedly asks the user to input a pair of integers. The program should record the largest number of each pair into a list. The program should keep asking the user to input pairs of numbers until the user enters -1 for the first number. At this point the program should print the list on a single line, with each value separated by a space and then stop.

Example of expected behaviour:

Please enter first number: 7

Please enter second number: 3

[ 7 has been stored ]

Please enter first number: 5

Please enter second number: 34

[ 34 has been stored ]

Please enter first number: 16

Please enter second number: 22

[ 22 has been stored ]

Please enter first number: -1

Please enter second number: 3

[ -1 entered: storage ends ]

The stored list is { 7 34 22 }

Answer 1

n1 = int(input("Please enter first number: "))
n2 = int(input("Please enter second number: "))
lst = []
while(n1!=-1 and n2!=-1):
    lst.append(max(n1,n2))
    print("[ " + str(lst[-1]) + " has been stored ]")
    n1 = int(input("Please enter first number: "))
    n2 = int(input("Please enter second number: "))
print("[ -1 entered: storage ends ]")
res = ""
for x in lst:
    res += str(x)
    res += " "
print("The stored list is { "+res+"}")
