ENED$1120-$ ACTIVITY

PYTHON $5$: LISTS

TASK $1($OF $4)$

OBJECTIVES: The student will review repetition structures and practice creating lists and indexing into a list.

TIMEKEEPER: This task should take approximately $20$ minutes. The time estimate is only a guideline $($some teams may use less time, while others may use more$).$

Develop a Python program that:

Imports the random library using the command: import random.

Prompts the user for the number of times, $N,$ to roll two dice $($should be a positive integer$).$

Checks to make sure $N$ is positive and continues to prompt until $N$ is greater than zero. Note: you don't have to check if $N$ is an integer because the int command with throw an error if user enters a decimal number.

Has a loop that rolls two dice $N$ times and stores the sum of the two dice in a list. Use a command such as: Dicel $=$ random. randint $(1,6)$ to simulate a dice roll.

Has a second loop that goes through the list and counts the number of times the sum of the two dice is $7.$ Note: it is certainly possible to do this count within the first loop; however, creating the second loop will allow you to practice indexing into a list.

Outputs both the list and the count.

Test your program using a relatively small number of rolls, $N.$ Results will vary since you are using a random function to generate the dice rolls, but you can look at your list and see if the count of sevens is correct.

Save your program as ACT Python$\_5$p$1\_$UCusername.py
