operator.methodcaller(name[, args...])
Return a callable object that calls the method name on its operand. If additional arguments and/or keyword arguments are given, they will be given to the method as well. For example:
After f = methodcaller('name'), the call f(b) returns b.name(). After f = methodcaller('name', 'foo', bar=1), the call f(b) returns b.name('foo', bar=1).
Equivalent to:
def methodcaller(name, *args, **kwargs):
def caller(obj):
return getattr(obj, name)(*args,
