Programming for Everybody: Assignment 05.2 Loops and Iteration - edorlando07/datasciencecoursera GitHub Wiki

###Getting Started with Python

5.2 Write a program that repeatedly prompts a user for integer numbers until the user enters 'done'. Once 'done' is entered, print out the largest and smallest of the numbers. If the user enters anything other than a valid number catch it with a try/except and put out an appropriate message and ignore the number. Enter the numbers from the book for problem 5.1 and Match the desired output as shown.

largest = None
smallest = None

while True:
    try:
        num = raw_input("Enter a number: ")
        if num == "done": break
        num = int(num)

        if largest < num:
            largest = num
        if smallest > num or smallest == None:
            smallest = num
    except:
        print "Invalid input"

print "Maximum is", largest
print "Minimum is", smallest

The input/output for code above is the following:

Enter a number: 4
Enter a number: 5
Enter a number: bad data
Invalid input
Enter a number: 7
Enter a number: done
Maximum is 7
Minimum is 4
