gives expr with the last element removed.

Details

  • Most[expr] is equivalent to Drop[expr,-1].

Examples

open all close all

Basic Examples  (2)

Wolfram Language code: Most[{a, b, c, d}]
Wolfram Language code: Most[<|1 :> a, 2 -> b, 3 :> c|>]

Generalizations & Extensions  (2)

The head need not be List:

Wolfram Language code: Most[a + b + c + d]
Wolfram Language code: Most[f[a, b, c, d]]

Most works on SparseArray objects:

Wolfram Language code: Most[SparseArray[Range[100]]]

Applications  (1)

Nest the operation of finding most of a list:

Wolfram Language code: NestList[Most, {a, b, c, d, e}, 3]

Properties & Relations  (1)

Most[expr] is equivalent to Drop[expr,-1]:

Wolfram Language code: Most[{a, b, c, d}]
Wolfram Language code: Drop[{a, b, c, d}, -1]

Possible Issues  (2)

The expression is evaluated before Most is applied:

Wolfram Language code: Most[c + a + b]

Most always operates on the FullForm of expressions:

Wolfram Language code: Most[1 / b]
Wolfram Language code: FullForm[1 / b]
