LEXICAL ANALYSIS

A Python program is divided into a number of logical lines. A Python program is read by a parser. Input to the parser is a stream of tokens, generated by the lexical analyzer.

SIMPLE STATEMENTS

https://docs.python.org/3/reference/simple_stmts.html

A simple statement is comprised within a single logical line. Several simple statements may occur on a single line separated by semicolons.

Examples: expression, assignment, assert, pass, del, return, yield, raise, break, continue, import, global, nonlocal.

COMPOUND STATEMENTS

https://docs.python.org/3/reference/compound_stmts.html

Compound statements contain other statements. In general, compound statements span multiple lines, although in simple incarnations a whole compound statement may be contained in one line.

Examples: if, while, for, try, with, def, class.
