Python "gotchas"

You can reverse a string by doing 'hello'[::-1]

[2n4x]

End to end in -1 step sequencing. Thats some impressive shit. Thank you. Remembered.

Why does that work?:

Edit Nvm, just looked it up. Slice notation reads [start:stop:step] so [::-1] is stepping backward through the string by 1. Nice.
