How do I remove a range (subsection) of a list in Python?

I have a simple, always-consecutive-ordered list like this: ``` all = [ 1, 2, 3, 4, 5, 6 ] # same as range( 1, 7 ) ``` I also have `current = 4`. In the end I want the `all` list to look like this ``` altered = [ 1, 2, 5, 6 ] ``` So what happened was it removed the `current` number and the one before it `3`. `current` can also be `1` and `0`, so I want to make sure it doesn't throw an error for those two values. For the exception `current = 0`, the altered list is like this ``` altered = [ 1, 2, 3, 4, 5 ] ``` Which means that `current = 0` simply removes the last number. I feel like you can probably code something fancy with generators, but I suck at writing them. Thanks in advance! Bonus points for doing this in one line. If the `current = 0` is too much trouble, then it could also be `current = -1` or `current = 7`. EDIT: Make sure to check for `current = 1`, which should be ``` altered = [ 2, 3, 4, 5, 6 ] ```
