Activity

• look at this example:

# Created by: Mr. Coxall

# Created on: Sep 2016

# Created for: ICS3U

# This program, creates an array, passes it to a function that finds its sum

def sum_array(array_numbers = []):

    # finds the sum of all the numbers in the array

    array_sum = 0

    for a_value in array_numbers:

        array_sum = array_sum + a_value

    return array_sum

the_array = [5,7,3,9,2,8]

the_total = sum_array(the_array)

print(the_total)

Daily Assignment

• create a program that has a function that will accept an array
• the function MUST use a For ... In loop
• it will find the smallest value in the array and pass it back as a single variable
• it could be a console program
• create:
  • flowchart - only for the function
  • Test cases
  • code
  • screenshots
  • GitHub link

Extra

• work on the weekly assignment

Homework!
