A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java. However, there are some ...
Parse tree of Python code with inset tokenization. The syntax of textual programming languages is usually defined using a combination of regular expressions (for lexical structure) and Backus–Naur form (a metalanguage for grammatical structure) to inductively specify syntactic categories (nonterminal) and terminal symbols.

Metasyntactic variables used commonly across all programming languages include foobar, foo, bar, baz, qux, quux, corge, grault, garply, waldo, fred, plugh, xyzzy, and thud. [1] [3] Two of these words, plugh and xyzzy, are taken from the game Colossal Cave Adventure. [4] A fuller reference can be found in The Hacker's Dictionary from MIT Press.
With respect to a language definition, the syntax of Comments can be classified many ways, including: Line vs. block – a line comment starts with a delimiter and continues to the end of the line (newline marker) whereas a block comment starts with one delimiter and ends with another and can cross lines
X +max is the maximal projection; the lexical category cannot project to any further point in the tree; X +min is the minimal projection, and corresponds to the lexical item without any of its associated projects (if any) X-max,-min lies between minimal and maximal projection( this corresponds to the intermediate projection level in X-bar Theory)

In terms of phrase structure rules, phrasal categories can occur to the left of the arrow while lexical categories cannot, e.g. NP → D N. Traditionally, a phrasal category should consist of two or more words, although conventions vary in this area. X-bar theory, for instance, often sees individual words corresponding to phrasal categories ...
Since Merge is an operation that combines two elements, a node under the Minimalist Program needs to be binary just as in the X-bar theory, although there is a difference between the theories in that under the X-bar theory, the directionality of branching is fixed in accordance with the principles-and-parameters model (not with the X-bar theory ...
