Last Updated :

Math module in Python contains a number of mathematical operations, which can be performed with ease using the module. math.prod()
method in Python is used to calculate the product of all the elements present in the given iterable. Most of the built-in containers in Python like list, tuple are iterables. The iterable must contain numeric value else non-numeric types may be rejected.
This method is new in Python version 3.8.
Syntax: math.prod(iterable, *, start = 1)
Parameters:
iterable: an iterable containing numeric values
start: an integer representing the start value. start is a named (keyword-only) parameter and its default value is 1.
Returns: the calculated product of all elements present in the given iterable.
Code #1: Use of math.prod()
method
import math
arr = [ 1 , 2 , 3 , 4 , 5 ]
product = math.prod(arr)
print (product)
tup = ( 0.5 , 0.6 , 0.7 )
product = math.prod(tup)
print (product)
seq = range ( 1 , 11 )
product = math.prod(seq)
print (product)
|
Code #2: if start parameter is explicitly specified
import math
arr = [ 1 , 2 , 3 , 4 , 5 ]
product = math.prod(arr, start = 2 )
print (product)
|
Code #3: When the given iterable is empty
import math
arr = []
product = math.prod(arr)
print (product)
tup = ()
product = math.prod(tup, start = 5 )
print (product)
