Find largest number from user input

Question

I trying to make a code which print largest and smallest number from user input. I want that user can input the number until there is ValueError

I have tried something like this:

value = raw_input(">")

largest_so_far = None
smalest_so_far = None

while(value):
    if value > largest_so_far:
        largest_so_far = value
    if ValueError:
        print largest_so_far

this code creates infinite loop. So how can I make it finite.

Answer 1

You need to use try and except here.

while(True):
    try:
         value = float(raw_input(">"))     # Get the input from user
         if value > largest_so_far:        # Type cast to integer
            largest_so_far = value
    except ValueError as e:                # Handle ValueError
        print largest_so_far
        break                              # Break the infinite loop
