How to formally document a multipledispatch function?

[pw2wang]

I'm using the package to write my own multiple dispatch functions.
The functions work well, but I found it is hard to deal with the documentation.
When I want to use help() function to read the documentation, I found it is hard to let users understand the usage of this function.
Is it a way to make it readable for users?
Here is my example:

from multipledispatch import dispatch

@dispatch(int)
def f(x):
    '''
    function for int
    '''
    return "this is int"
    
@dispatch(str)
def f(x):
    '''
    function for string 
    '''
    return "this is string"

help(f)

I came here to ask the same question, anyone figure out something that works well?

I think this might work well - just write the documentation in one spot like so:

@dispatch(pd.DataFrame, pd.Series)
def foo(x, y) -> pd.DataFrame:
    ...implementation...

@dispatch(pd.DataFrame, pd.DataFrame)
def foo(x, y) -> pd.DataFrame:
    ...implementation...

foo.__doc__ = \
    """
    Docs go here
    """

Update: I guess that doesn't work, I get the exception AttributeError: can't set attribute.
