Text representations of Python  objects

It is not  possible to output an object directly, because an object is not text. For this reason, in order to output an object, a text representation of the object is created. This text representation  is a text representing the object and can then be output. The process of the production of a text representation will also be called text representation.

When an expression is entered into the console, it is being evaluated. After the evaluation of the entered expression, a text representation  of the object obtained is output.

Evaluation in the console

"Hello, world!"↵

'Hello, world!'

The expression »"Hello, world!"« is evaluated  above. The evaluation results in an object. The text representation  of that object is then »'Hello, world!'«.

The text representation of an object is normally used whenever this object is to be output  on a text medium.

Evaluation of the expression »"Hello, world!"« and text representation of the object obtained

                         evaluation                       text representation
"Hello, world!"  --------------------> Hello, world! -------------------------> 'Hello, world!'
  Expression                              object                             text representation
   a text                               not a text                                 a text

Evaluation of an expression with subsequent text representation of the object obtained

                     evaluation           text representation
expression  --------------------> object ---------------------> text representation

A text representation of an object often does not contain all  information about the object.

The term “text representation of an object ” belongs to the run-time model.
