Often, we’ll need to find the number of items in a list, usually called its length.

We can do this using a built-in function called `len()`.

When we apply `len()` to a list, we get the number of elements in that list:

``````my_list = [1, 2, 3, 4, 5]

print(len(my_list))``````

Would output:

``5``

Let’s find the length of various lists!

### Instructions

1.

Calculate the length of `long_list` and save it to the variable `long_list_len`.

2.

Use `print()` to examine `long_list_len`.

3.

We have provided a completed `range()` function for the variable `range_list`.

Calculate its length using the function `len()` and save it to a variable called `range_list_length`.

Note: Range objects do not need to be converted to lists in order to determine their length

4.

Use `print()` to examine `range_list_length`.

5.

Change the `range()` function that generates `range_list` so that it skips `100` instead of `10` steps between items.

How does this change `range_list_len`?
