Do the following using indexing: Store the first value in `list_1` to `extraction_1` Store the third value from the end of `list_2` to `extraction_2` Store the last three values of `list_4` to `extraction_3` Store the first three values of `list_3` to `extraction_4` Notes: Values must be stored in the same order they appear in the original list in your output. Be sure to execute the cell below to define the lists prior to referencing them in your answer. Because indexing starts at 0, when we say "first" item we mean item number 0, and the "second" item is item number 1, etc. important: make sure you are using indexing rather than hard-coding, as we will change the value of `list_1`, `list_2`, `list_3` and `list_4` during testing.
