## Multiply All Elements in list of PythonIn 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
Let's start with the first one, ## Traversing the listConsider the program given below-
The multiplication of all the elements of list_value1 is: 240240 The multiplication of all the elements of list_value2 is: 5040
It'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 NumPyThe following program illustrates how it can be done in Python.
The multiplication of all the elements of list_value1 is: 240240 The multiplication of all the elements of list_value2 is: 5040
Let'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 lambdaThe program given below demonstrates the same-
The multiplication of all the elements of list_value1 is: 240240 The multiplication of all the elements of list_value2 is: 5040
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.
## ConclusionIn this tutorial, we learned the various approaches of multiplying the elements present in the list in Python. |
