Chapter 7: Problem 6

How do you find the number of elements in a list?

Short Answer

Expert verified
A: The three steps are: 1. Define the list. 2. Use the len() function to find the number of elements. 3. Print the number of elements.

Step by step solution

01

Define the list

For this example, let's define a list containing some numbers: ``` example_list = [1, 4, 6, 8, 18, 21, 25] ``` This list consists of 7 elements.
02

Use the len() function to find the number of elements

We can use Python's built-in function called `len()` to find the number of elements in a list. The `len()` function takes the list as an input and returns the number of elements in the list. ``` number_of_elements = len(example_list) ``` Now, the `number_of_elements` variable contains the number of elements in the `example_list`.
03

Print the number of elements

Finally, we will print the result to see the number of elements in the list. ``` print("The number of elements in the list is:", number_of_elements) ``` By following these three steps, you will be able to find the number of elements in any list.
