Program Plan Intro

Sum of values in the list:

• • In Python, to sum the values in a given list, a “for” loop is employed.
• • A “for” loop can be used to iterate and process each data elements using the list indexing and compute the sum of the list.

Algorithm:

Algorithm to compute the sum of the values in a given list is as follows:

• • Create a list of integers and declare a variable named “listIntegers” to refer the list.
• • Declare a variable named “totalSum” and initialize it to zero.
• • Declare a variable named “index” and initialize it to zero.
• • Use a “for” loop to iterate and process through the list from starting index to the last index.
• • Every time the “for” loop processes an “index”, add the index to the “totalSum”.
• • When the “for” loop ends, use a “print()” to display the “totalSum” which gives the total value of the list.
