Python Python Collections (2016, retired 2019) Lists Creating lists

Need help clarifying what challenge is asking.

I'm having trouble comprehending what this challenge is asking?

lists.py
my_list = [1, 2, 3, 'abc', 'bde']
second_list = my_list + [4, 5]


This challenge is just meant as a refresher. Create a single new list variable named my_list.
Put 3 numbers and 2 strings into it in whatever order you want. For the last member, though, add another list with 2 items in it.

You almost got it.

You're being asked to create a list variable, and put 3 numbers and 2 strings inside of it. Which you've done.

# Create a list variable called my_list
# Add 3 numbers and two strings into it

my_list = [ 1, 2, 3, 'abc', 'bde' ]

Now I assume it's the 'For the last member' part that's tripped you up? You need to place a second list as the last item of your list variable.

So, add some square ([ ]) brackets as the last item of your list variable, then add 2 items inside this new second (nested) list.

# Add a second list 'For the last member'
# 'last member' meaning the last item of your list variable.
# my_list = [ 1, 2, 3, 'abc', 'bde', [ ] ]
my_list = [ 1, 2, 3, 'abc', 'bde', [4, 5] ]

You can also do this using pythons 'append' method:

# Create a list variable named 'my_list'
# Place 3 numbers and two strings into it
my_list = [ 1, 2, 3, 'abc', 'bde' ]

#For the last object in the list
# create a second list and add it to the end of your list variables list using 'append':
my_list.append([ 4, 5 ])

Either way you decide to do it, printing your list to the screen should look something like this:

print( my_list )

 [ 1, 2, 3, 'abc', 'bde', [4, 5] ]                                                                              

Hope that helps!

That did the trick, thanks!
