# Multiply All Elements in list of Python

In this tutorial, we will learn how we can multiply all the elements of a list in Python.

Let us have a look at some examples to understand our objective-

We can observe that in the output we have obtained the product of all the elements present in the list.

Since the first element is three, a is printed three times in the output.

We will learn the following methods-

- Traversing the list
- Using NumPy
- Using lambda

Letâ€™s start with the first one,

## Traversing the list

Consider the program given below-

**Output:**

The multiplication of all the elements of list_value1 is: 240240 The multiplication of all the elements of list_value2 is: 5040

**Explanation-**

Itâ€™s time to have a look at the explanation of the above program-

- In the first step, we have created a function that will make the list as an input.
- In the function definition, we have used a for loop that takes each element from the list, multiplies it with one initially, and then prints the resultant value of the product.
- In the next step, we have initialized the lists and then passed them into our function.
- On executing this program, the desired output is displayed.

In the second program, we will see how NumPy can help us to implement the same.

## Using NumPy

The following program illustrates how it can be done in Python.

**Output:**

The multiplication of all the elements of list_value1 is: 240240 The multiplication of all the elements of list_value2 is: 5040

**Explanation-**

Letâ€™s understand what we have done in the above program.

- In the first step, we have imported the NumPy module.
- In the next step, we have initialized the values of the two lists, list_value1 and list_value2.
- After this, we will use
**prod()**that will compute the product of the elements present in the lists. - On executing the program, the expected output is displayed.

Finally, we will learn how lambda can be used to multiply the elements of our list.

## Using lambda

The program given below demonstrates the same-

**Output:**

The multiplication of all the elements of list_value1 is: 240240 The multiplication of all the elements of list_value2 is: 5040

**Explanation-**

Let us understand what happened in the above program.

- In the first step, we have imported reduce from
- After this, we have initialized the two lists,
**list_value1**and**list_value2**. - We have used the precise way of defining functions, which is lambda, and then provided the required functionality.
- On executing the program, the desired values are displayed.

## Conclusion

In this tutorial, we learned the various approaches of multiplying the elements present in the list in Python.
