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?

从 Python Standard Library documentation 的“Built-in Functions”部分开始，检查 repr(object, /) 周围的函数签名表示法。添加一个表示法说明，解释斜杠以及在那里识别出的任何其他非标准表示法；当读者无需查找其他资料就能理解这些签名时，文档就完成了。
