# 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](https://docs.python.org/3/library/functions.html#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](https://docs.python.org/3/library/functions.html) or at the [beginning of the documentation](https://docs.python.org/3/library/index.html).
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?
Looking for the meaning of the "/", I went to the beginning of the section, but to no avail.
