Expressions in Python 

A large program  is made up of many small programs. Some of these small programs are called expressions.

An expression  is a sequence of characters  that is constructed according to certain rules, which will be specified later.

For example, one such rule is: An expression that starts with a quotation mark »"« must contain another quotation mark. So »"Hello, world"« is an expression, but »"Hello, world'« is not.

an expression

"Hallo, Welt"

not  an expression

"Hallo, Welt

The Source-Code Model

A model  is a description, and an entity of a model  is something that is described in the model.

The source code model  is the description of the structure of the source code.

Expressions  are entities of the source-code model.

That is, expressions are terms used to describe the source code. They belong to the topic of the source code.
