Totaling the Values in a List in Python:-

Assuming a list contains numeric values, to calculate the total of those values you use a loop with an accumulator variable. The loop steps through the list, adding the value of each element to the accumulator. Program (specified below) demonstrates the algorithm with a list named numbers.

(total-list.py)

# This program calculates the total of the values in a list #.

def main ( ):

# Create a list.

numbers = [2, 4, 6, 8, 10]

# Create a variable to use as an accumulator.

total = 0

# Calculate the total of the list elements.

for value in numbers:

total += value

# Display the total of the list elements.

print 'The total of the elements is', total

# Call the main function.

main ( )

Output

The total of the elements is 30
