理解syntactical sugar

• Overview

  If a language provides convenient, compact shortcuts, then those shortcuts may be described as syntactical sugar, a term coined in 1964.

  The built-in dictionary data structure in Python is syntactic sugar for an associative matrix/list.

• Syntactic sugar

  Syntactic sugar is syntax within a programming language that is designed to make things easier to read or to express.

  It makes the language “sweeter” for human use: things can be expressed more clearly, more concisely, or in an alternative style that some may prefer.

  The term syntactic sugar was coined by Peter J. Landin in 1964.
