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 ``*``. Likewise ``varkwargs`` can be the name for a variable keyword argument placeholder like ``**``. 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. rzinvalid argument name: {0}Nz, z, *{0}z __{0}__funcz _kwargs{0}z , {0}={1}z , {0}={0}z, **{0}Úéz.pycz.pyzÚ__main__zE{0} def {name}({sig1}): return __{name}__func({sig2}) Ú )ÚnameZsig1Zsig2Zsingle)"Ú isinstanceÚdictÚitemsÚiterÚ itertoolsÚchainÚtupleÚappendÚkeywordÚ iskeywordÚ _ARGNAME_REÚmatchÚ SyntaxErrorÚformatÚjoinÚ__name__Ú enumerateÚlstriprÚinspectZ currentframeÚf_backÚ__file__ÚendswithÚosÚpathÚsplitextÚf_linenoÚtextwrapÚdedentÚcompileÚevalÚ __module__Ú__doc__)ÚfuncÚargsÚkwargsZvarargsZ varkwargsr Zpos_argsZkey_argsZ iter_kwargsÚitemÚargnameZ def_signatureZcall_signatureZ global_varsZ local_varsÚidxÚkeyÚvalueZ default_varÚmodZfrmÚfilenameÚmodnameÚlinenoÚtemplateÚcodeÚnew_funcrrú4lib/python3.7/site-packages/astropy/utils/codegen.pyrsn              ) r*rrrr!Úrer%Z introspectionrÚ__all__r'rrrrrr:Ús
