Question

Using a Python environment, complete two small Python programs -

1. Write a function which repeatedly reads numbers until the user enters “done”

• Once “done” is entered, print out the sum, average, maximum, and minimum of the values entered
• If the user enters anything other than a number, detect their mistake using try and except and print an error message and skip to the next number.

2. Write another function so that it draws a sideways tree pointing right; for example, if the user enters 4, the program would print

Answer 1

s = input("Enter input: ")
total = 0
count = 0
maxValue = None
minValue = None
while(s!="done"):
    try:
        n = int(s)
        total += n
        count += 1
        if maxValue==None or maxValue<n:
            maxValue = n
        if minValue==None or minValue>n:
            minValue = n
    except Exception as ex:
        print("Invalid input...")
    s = input("Enter input: ")
print("Sum:",total)
print("Average:",(total/count))
print("Maximum:",maxValue)
print("Minimum:",minValue)
