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?

從 Python Standard Library documentation 的「Built-in Functions」部分開始，檢視 repr(object, /) 周圍的函式簽章表示法。新增一個表示法說明，解釋斜線以及在該處識別出的任何其他非標準表示法；當讀者無需查找其他資料就能理解這些簽章時，文件就完成了。
