#### 💡 Explanation: #### 💡 Explanation:
* `a += b` doesn't always behave the same way as `a = a + b`. Classes *may* implement the op= operators differently, and lists do this. * `a += b` doesn't always behave the same way as `a = a + b`. Classes *may* implement the *`op=`* operators differently, and lists do this.
* The expression `a = a + [5,6,7,8]` generates a new list and sets `a`'s reference to that new list, leaving `b` unchanged. * The expression `a = a + [5,6,7,8]` generates a new list and sets `a`'s reference to that new list, leaving `b` unchanged.
