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_length`

?
