Question

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

Short answer

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

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.

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`.

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.
