No   First off  append is a function  so you can t write append i 1 i 4  because you re trying to get a slice of a thing that isn t a sequence   You can t get an element of it  either  append i 1  is wrong for the same reason   When you call a function  the argument goes in parentheses  i e  the round ones        Second  what you re trying to do is  take a sequence  and put every element in it at the end of this other sequence  in the original order   That s spelled extend  append is  take this thing  and put it at the end of the list  as a single item  even if it s also a list    Recall that a list is a kind of sequence    But then  you need to be aware that i 1 i 4 is a special construct that appears only inside square brackets  to get a slice from a sequence  and braces  to create a dict object   You cannot pass it to a function  So you can t extend with that  You need to make a sequence of those values  and the natural way to do this is with the range function

Use this     Inputs L1    1  2  L2    3 4 5    Code L1 L2   Output  1  2  3  4  5    By using the     operator you can skip the multiple append  amp  extend operators in just one line of code and this is valid for more then two of lists by L1 L2 L3 L4       etc   Happy Learning

No  The method for appending an entire sequence is list extend      gt  gt  gt  L    1  2   gt  gt  gt  L extend  3  4  5    gt  gt  gt  L  1  2  3  4  5
