Python’s sum() Function

Here, iterable represents the iterable object whose elements’ sum is to be calculated, and start denotes the optional initial value for the sum (default is 0).

Example 1: Sum of Numbers in a List

numbers = [1, 2, 3, 4, 5]
result = sum(numbers)
print("Sum of numbers:", result)

Output 1:

Sum of numbers: 15

Example 2: Sum of Numbers in a Tuple

numbers_tuple = (10, 20, 30, 40, 50)
result = sum(numbers_tuple)
print("Sum of numbers in tuple:", result)

Output 2:

Sum of numbers in tuple: 150

Example 3: Sum of Floating Point Numbers

float_numbers = [1.5, 2.5, 3.5, 4.5, 5.5]
result = sum(float_numbers)
print("Sum of floating point numbers:", result)

Output 3:

Sum of floating point numbers: 17.5

Example 4: Sum with Custom Start Value

numbers = [1, 2, 3, 4, 5]
start_value = 10
result = sum(numbers, start_value)
print("Sum of numbers with start value 10:", result)

Output 4:

Sum of numbers with start value 10: 25

Points to Remember

• The sum() function calculates the sum of elements in iterables.
• It can handle both numerical and non-numerical elements in the iterable.
• The start parameter allows customization of the initial value for the sum.
