**Python** is a high-level programming language that offers various modules that allow for clean and consistent code. The **`math`** module provides a range of mathematical functions and constants that make operations straightforward. One such function is **`math.fsum()`**, which returns the sum of all values in an iterable, such as tuples, arrays, lists, etc.

#              
## Syntax

#         
#  Parameters
* `iterable`: Any iterable, such as a list, tuple, or array. Returns a `TypeError` if the values of `iterable` are not numbers. This parameter is required.

#            
## Return value
This function returns the sum of all values in `iterable` in the form of a `float` value.

## Code example

#import library
import math

#initialize lists
a = [3, 6, 9, 4, 7]
b = [6, 8.44, 15, 5.4]
c = [5.8, 8.3, 2.9, 1.7, 4.3]

#initialize tuples
d = (4, 6, 8, 1, 3)
e = (8.1, 7, 2.00, 2)
f = (6.4, 9.1, 2.5, 6.1)

#print the sums of the iterables
print(a, ':', math.fsum(a))
print(b, ':', math.fsum(b))
print(c, ':', math.fsum(c))
print(d, ':', math.fsum(d))
print(e, ':', math.fsum(e))
print(f, ':', math.fsum(f))
