# Drop

Drop[list, n]
gives list with its first n elements dropped.

Drop[list, -n]
gives list with its last n elements dropped.

Drop[list, {n}]
gives list with its n element dropped.

Drop[list, {m, n}]
gives list with elements m through n dropped.

Drop[list, {m, n, s}]
gives list with elements m through n in steps of s dropped.

Drop[list, seq1, seq2, ...]
gives a nested list in which elements specified by have been dropped at level i in list.

## DetailsDetails

• Drop uses the standard sequence specification:
•  All all elements None no elements n elements 1 through n -n last n elements {n} element n only {m,n} elements m through n inclusive {m,n,s} elements m through n in steps of s
• Drop can be used on an object with any head, not necessarily List.
• For a matrix, Drop[list, seq1, seq2] effectively drops all elements except those in a submatrix of list.
• Drop works on SparseArray objects.
