Slash notation should be defined in a notation key at the beginning of the Built-In Functions section

Documentation

The Standard Library defines a number of built-in functions, and a shorthand notation is used when a function is defined, such as the definition of repr:

repr(object, /)

But there is no information about what that "/' means in the function signature. It is not standard computer science notation, so I started looking for its meaning. Normally, a notation key should be at the beginning of the document or section, but I do not find a notation key either at the beginning of the section or at the beginning of the documentation.

Could a notation key be added please, to define the meaning of this and any other non-standard notation that is used in the Python documentation?

Python Standard Library documentation の「Built-in Functions」セクションから始め、repr(object, /) 周辺の関数シグネチャ表記を確認します。スラッシュと、そこで特定したその他の標準外の表記を説明する表記キーを追加します。読者が別の場所を検索せずにこれらのシグネチャを理解できるようになった時点で、ドキュメントは完成です。
