Attribute and method calling¶
- sage.misc.call.attrcall(name, *args, **kwds)[source]¶
- Return a callable which takes in an object, gets the method named name from that object, and calls it with the specified arguments and keywords. - INPUT: - name– string of the name of the method you want to call
- args, kwds– arguments and keywords to be passed to the method
 - EXAMPLES: - sage: f = attrcall('core', 3); f *.core(3) sage: [f(p) for p in Partitions(5)] # needs sage.combinat [[2], [1, 1], [1, 1], [3, 1, 1], [2], [2], [1, 1]] - >>> from sage.all import * >>> f = attrcall('core', Integer(3)); f *.core(3) >>> [f(p) for p in Partitions(Integer(5))] # needs sage.combinat [[2], [1, 1], [1, 1], [3, 1, 1], [2], [2], [1, 1]] 
- sage.misc.call.call_method(obj, name, *args, **kwds)[source]¶
- Call the method - nameon- obj.- This has to exist somewhere in Python!!! - See also - operator.methodcaller()- attrcal()- EXAMPLES: - sage: from sage.misc.call import call_method sage: call_method(1, "__add__", 2) 3 - >>> from sage.all import * >>> from sage.misc.call import call_method >>> call_method(Integer(1), "__add__", Integer(2)) 3
