In computer science, an abstract syntax tree ( AST), or just syntax tree, is a tree representation of the abstract syntactic structure of source code written in a programming language. Each node of the tree denotes a construct occurring in the source code.
The syntax is " abstract" in the sense that it does not represent every detail appearing in the real syntax, but rather just the structural. fix_ missing_ locations ( node) ¶ When you compile a node tree with compile( ), the compiler expects lineno and col_ offset attributes for every node that supports them.
This is rather tedious to fill in for generated nodes, so this helper adds these attributes recursively where not already set, by setting them to the values of the parent node. A parser is a software component that takes input data ( frequently text) and builds a data structure – often some kind of parse tree, abstract syntax tree or other hierarchical structure, giving a structural representation of the input while checking for correct syntax.
The parsing may be preceded or followed by other steps, or these may be combined into a single by: Capitalized variables contain constants and class/ module names.
