# How To Multiply All Elements In A List In Python

If you want to find the answer to how to multiply all elements in a list in Python, this whole article is what you are looking for. Let’s read it right now.

## List in Python

In Python, a data type allows storing many different data types and accessing the elements inside it through the position of that element in the list. A list can be considered a sequential array in other languages ​​(like vector in C++ and ArrayList in Java). Lists are not necessarily homogeneous, making them one of Python’s most potent tools. A single list can include Datatypes such as integers, strings, and objects. Lists are mutable even after they are created.

The list in Python is ordered and has a definite number. The elements in the list are indexed in a specified sequence, and the indexing of the list is performed with 0 as the first index. Each element in the list has a specified position in the list. This allows the elements in the list to be duplicated, with each element having a distinct position and confidence.

Code:

# Creating a List
numbers = []

# Creating a List of numbers
numbers = [1, 2, 3]

# Creating a List of strings and accessing
numbers = ["One", "Two", "Three"]

# Creating a Multi-Dimensional List
numbers = [['One', 'Two'] , ['Three']]

And those are some ways to create lists in Python.

## Multiply all elements in a list in Python

### Use reduce() method

The reduce method is a function that takes two input parameters, function f and sequence. Instead of iterating over each element, reduce will combine each of the two elements of an array with the input function f.

We can apply the reduce() method in Python to find the product of numbers in an array. This function is defined in the module “functools”. Here is how to do it.

Code:

from functools import reduce

numbers = [2,4,6,8,10]
print(reduce(lambda x, y: x*y, numbers))

Output:

3840

So we could calculate the value after multiplying all the values ​​in the list numbers together.

### Use for loop

For loop in Python programming language and its variants, how to iterate over a sequence of elements in Python such as list, string or other iterable objects. So we will iterate through each element in the list and multiply them to get the product of all the elements.

Code:

numbers = [2,4,6,8,10]
mul = 1

for num in numbers:
mul = mul*num

print(mul)

Output:

3840

With this approach, we can also get the result of multiplying all the elements in the list and storing it in the mul variable. I hope these methods can help you.
