Question

Compute the average of a list of user-entered integers representing rolls of two dice. The list ends when 0 is entered. Integers must be in the range 2 to 12 (inclusive); integers outside the range don't contribute to the average. Output the average, and the number of valid and invalid integers (excluding the ending 0). If only 0 is entered, output 0. The output may be a floating-point value.Ex: If the user enters 8 12 13 0, the output is:Average: 10Valid: 2Invalid: 1Hints:

Answer 1

Answer:

mylist = []

total = 0

valid = 0

invalid = 0

num = int(input("Number: "))

while num != 0:

    mylist.append(num)

    if(num>=2 and num<=12):

         total = total + num

         valid = valid + 1

    else:

         invalid = invalid + 1

    num = int(input("Number: "))

   

print("Average: "+str(total/valid))

print("Valid: "+str(valid))

print("Invalid: "+str(invalid))

   

Explanation:

The solution is implemented in Python

This line defines an empty list

mylist = []

The next three lines initializes total, valid input and input to 0 respectively

total = 0

valid = 0

invalid = 0

This line prompts user for input

num = int(input("Number: "))

This loop is repeated while input number is not 0

while num != 0:

This adds input number to the list

    mylist.append(num)

This checks for valid inputs

    if(num>=2 and num<=12):

If valid, the sum is calculated

         total = total + num

And the number of valid inputs is incremented by 1

         valid = valid + 1

If otherwise,

    else:

The number of invalid inputs is incremented by 1

         invalid = invalid + 1

This prompts user for another input

    num = int(input("Number: "))

   

This calculates and prints the average

print("Average: "+str(total/valid))

This prints the number of valid inputs

print("Valid: "+str(valid))

This prints the number of invalid inputs

print("Invalid: "+str(invalid))
