Python Program for fsum() Function

In the previous article, we have discussed Python Program for frexp() Function
fsum() Function in Python:

The math.fsum() method returns the sum of all iterable items (tuples, arrays, lists, etc.).

Syntax:

math.fsum(iterable)

Parameters:

iterable: This is required. It may be a tuple, list, arrays, etc to sum. If the iterable does not contain numbers, it throws a TypeError.

Return Value:

It returns a float value representing the sum of the iterable’s items.

Examples:

Example1:

Input:

Given List = [1, 3, 5, 8]
Given Tuple = (10, 20, 50, 60)

Output:

The sum of all list items after applying fsum() function =  17.0
The sum of all tuple items after applying fsum() function =  140.0

Example2:

Input:

Given List = [15, 20, 40, 10, 30]
Given Tuple = (45, 30, 10, 5, 6)

Output:

The sum of all list items after applying fsum() function =  115.0
The sum of all tuple items after applying fsum() function =  96.0

Method #1: Using Built-in Functions (Static Input)

Approach:

Import math module using the import keyword.
Give the list as static input and store it in a variable.
Give the tuple as static input and store it in another variable.
Apply math.fsum() function to the given list to get the sum of all list items.
Store it in another variable.
Print the above result list sum.
Apply math.fsum() function to the given tuple to get the sum of all tuple items.
Store it in another variable.
Print the above result tuple sum.
The Exit of Program.

Below is the implementation:

# Import math module using the import keyword.
import math
# Give the list as static input and store it in a variable.
gvn_lst = [1, 3, 5, 8]
# Give the tuple as static input and store it in another variable.
gvn_tupl = (10, 20, 50, 60)
# Apply math.fsum() function to the given list to get the sum of all list items.
# store it in another variable.
lst_sum = math.fsum(gvn_lst)
# print the above result list sum.
print("The sum of all list items after applying fsum() function = ", lst_sum)
# Apply math.fsum() function to the given tuple to get the sum of all tuple items.
# store it in another variable.
tupl_sum = math.fsum(gvn_tupl)
# print the above result tuple sum.
print("The sum of all tuple items after applying fsum() function = ", tupl_sum)

Output:

The sum all list items after applying fsum() function =  17.0
The sum all tuple items after applying fsum() function =  140.0

Method #2: Using Built-in Functions (User Input)

Approach:

Import math module using the import keyword.
Give the list as user input using list(),map(),input(),and split() functions.
Store it in a variable.
Give the tuple as user input using list(),map(),input(),and split() functions.
Store it in another variable.
Apply math.fsum() function to the given list to get the sum of all list items.
Store it in another variable.
Print the above result list sum.
Apply math.fsum() function to the given tuple to get the sum of all tuple items.
Store it in another variable.
Print the above result tuple sum.
The Exit of Program.

Below is the implementation:

# Import math module using the import keyword.
import math
# Give the list as user input using list(),map(),input(),and split() functions.
# Store it in a variable.
gvn_lst = list(map(int, input(
   'Enter some random List Elements separated by spaces = ').split()))
# Give the tuple as user input using list(),map(),input(),and split() functions.
# Store it in another variable.
gvn_tupl = tuple(map(int, input(
   'Enter some random tuple Elements separated by spaces = ').split()))
# Apply math.fsum() function to the given list to get the sum of all list items.
# store it in another variable.
lst_sum = math.fsum(gvn_lst)
# print the above result list sum.
print("The sum of all list items after applying fsum() function = ", lst_sum)
# Apply math.fsum() function to the given tuple to get the sum of all tuple items.
# store it in another variable.
tupl_sum = math.fsum(gvn_tupl)
# print the above result tuple sum.
print("The sum of all tuple items after applying fsum() function = ", tupl_sum)

Output:

Enter some random List Elements separated by spaces = 15 20 40 10 30
Enter some random tuple Elements separated by spaces = 45 30 10 5 6
The sum of all list items after applying fsum() function = 115.0
The sum of all tuple items after applying fsum() function = 96.0
