This guide will help you understand how to multiply each number in your list in python with an emphasis on using list comprehensions.
Lists are a versatile data structure in Python that can hold multiple items in a single variable. You can also perform mathematical operations directly on lists by leveraging the ‘*’ operator. However, if you need to multiply each number in your list by the same value, then this guide will help you understand how it is done using list comprehensions.
Let’s consider we have a list of numbers
[1,2,3,4] and we want to double every element in the list. Here’s how you can do it:
list = [1,2,3,4]
doubled_list = [i*2 for i in list]
# Output: [2, 4, 6, 8]
This is how you can do it with a single line of code. Above we used the
for loop to iterate over each element
i in our list and then multiplied each number by 2. This result is assigned back to the
This concept is useful when you need to multiply every number in your list with a specific number. It’s very efficient and Pythonic way of accomplishing this task.
