An abstract syntax tree (AST) captures the essential structure of the input in a tree form, while omitting unnecessary syntactic details. An abstract syntax tree can be compiled into a Python code object using the built-in compile() function. That syntax tree then can be converted into a linear representation, e. The main difference between parse tree and syntax tree is that parse tree is a hierarchical structure that represents the derivation of the grammar to obtain input strings while syntax tree is a way of representing the syntax of a programming language as a hierarchical form similar to a tree. {{ variable }} and perform logic statements by surrounding them in a curly brace percentage sign e. Enter a phrase, or a text, and you will have a complete analysis of the syntactic relations established between the pairs of words that compose it: its kind of dependency relationship, which word is nuclear and which is dependent, its grammatical category and its position in the sentence.
