# make_function_with_signature

`astropy.utils.codegen.``make_function_with_signature`(func, args=(), kwargs={}, varargs=None, varkwargs=None, name=None)

  Make a new function from an existing function but with the desired signature.

  The desired signature must of course be compatible with the arguments actually accepted by the input function.

  The `args` are strings that should be the names of the positional arguments. `kwargs` can map names of keyword arguments to their default values. It may be either a `dict` or a list of `(keyword, default)` tuples.

  If `varargs` is a string it is added to the positional arguments as `*<varargs>`. Likewise `varkwargs` can be the name for a variable keyword argument placeholder like `**<varkwargs>`.

  If not specified the name of the new function is taken from the original function. Otherwise, the `name` argument can be used to specify a new name.

  Note, the names may only be valid Python variable names.
