Python: getattr
getattr(obj, name) allows to refer to an attribute in an object by its name given as
string:
class cls:
def __init__(self, ident):
self.ident = ident
def f1(self):
print('f1 was called, ident = {}'.format(self.ident))
def f2(self):
print('f2 was called, ident = {}'.format(self.ident))
def callMethodByName(obj, name):
method = getattr(obj, name)
method()
obj_1 = cls('one')
obj_2 = cls('two')
callMethodByName(obj_1, 'f1') # f1 was called, ident = one
callMethodByName(obj_2, 'f2') # f2 was called, ident = two
