hup.base.call module¶

Collection of helper functions for callables.

parameters(op: Callable, *args, **kwds) → collections.OrderedDict¶

Get parameters of a callable object.

Parameters:

Parameters:	op – Callable object args – Arbitrary arguments, that are zipped into the returned parameter dictionary. *kwds – Arbitrary keyword arguments, that respectively - if declared within the callable object - are merged into the returned parameter dictionary. If the callable object allows a variable number of keyword arguments, all given keyword arguments are merged into the parameter dictionary.
Returns:	Ordered Dictionary containing all parameters.

op – Callable object
*args – Arbitrary arguments, that are zipped into the returned parameter dictionary.
**kwds – Arbitrary keyword arguments, that respectively - if declared within the callable object - are merged into the returned parameter dictionary. If the callable object allows a variable number of keyword arguments, all given keyword arguments are merged into the parameter dictionary.

Returns:

Ordered Dictionary containing all parameters.

Examples

>>> parameters(parameters)
OrderedDict()
>>> parameters(parameters, list)
OrderedDict([('operator', list)])

parse(text: str) → Tuple[str, tuple, dict]¶

Split a function call in the function name, it’s arguments and keywords.

Parameters:	text – Function call given as valid Python code.
Returns:	A tuple consisting of the function name as string, the arguments as tuple and the keywords as dictionary.

safe_call(f: Callable, *args, **kwds) → Any¶

Evaluate callable object for given parameters.

Evaluates a callable for the subset of given parameters, which is known to the callables signature.

Parameters:	f – Callable object args – Arbitrary arguments *kwds – Arbitrary keyword arguments

Returns:
