[Python collections] extend function challenge

Hi everyone,

I am having issue with the above code challenge, Python collection, challenge 3, where you have to extend a list with the numbers from 1 through 20.

Here is what I have written:

temp_list = []
for i in range(1, 20):
  temp_list.append(i)

the_list.extend(temp_list)

And the error is:

"Oops! It looks like Task 1 is no longer passing."

I am sure this is wrong given that I might extend a list with another list, but I don't really know how to solve this issue. Any feedback will be appreciated, thanks in advance!

David

Why use a for loop? You already have the_list and you already have .extend(), which you can pass a range() to.

Also, remember that the_list should have [1, 2, 3] in it already. You want it to go up to 20, so where do you start the range at?

Starting at 4 that's right.

I tried:

the_list.extend(range(4, 21))

And that worked!

Thanks a lot!
