Slice Quote by Mark Lutz
![“This description requires elaboration when the value and the slice being assigned overlap: L[2:5]=L[3:6], for instance, works fine because the value to be inserted is fetched before the deletion happens on the left.” quote by Mark Lutz](https://sms4smile.com/quotes/img-quotes/a52/mark-lutz-25814_quote_this-description-requires-elaboration-wh_1302432.jpg)
““This description requires elaboration when the value and the slice being assigned overlap: L[2:5]=L[3:6], for instance, works fine because the value to be inserted is fetched before the deletion happens on the left.””
