You use self for the order_number but not for the line_items?
Also, are you really planning on building a collection of line
items per order before you create the order? Or might it be
better to create the order for the first identified line
item and then add() subsequent line items as you find them?
Just a thought...

And similarly you do not use self for bin_number
In each case the values without self will be thrown away when
the __init__() method exits.
Other than that issue it's a fair start in that you now have
two classes that can be used to store the data in the file.
Your next step is presumably to read the file into objects
of these classes.
Finally, I'm guessing you'll want to sort the line items into
groups based on their location so that the warehouse pickers
don't need to visit the same area twice. I'm not clear whether
that should be limited per order or to all the line items per
batch and the collected items assembled into orders later.
I'm assuming that the items are picked by order... but the
assignment doesn't seem to specify.
