I have an external function my_update_function which is not part of my class my_class (currently for design reasons). Now, I would like to update the internal parameters of my_class i.e. self.x and self.y using the external function my_update_function.
Please see this MWE, which describes my questions:
def my_update_function(arg1,args2):
"""
Updates arg1 and arg2.
"""
return arg1*arg1,arg2*arg2
class my_class(object):
def __init__(self):
self.x = 2
self.y = 3
def simulate(self):
my_update_function(self.x,self.y)
However, I am wondering if there is some way (either by class re-design or otherwise) that I can update self.x and self.y without having to save the output of the function my_update_function as parameter values (and without having to include my_update_function as part of my class my_class) i.e I would rather not write this:
def simulate(self):
self.x, self.y = my_update_function(self.x,self.y)
but would want it to be like this:
def simulate(self):
my_update_function(self.x,self.y)
so that my_update_function communicates the updated parameter values to the class without having to explicitly store them as outputs.
Please let me know if it is not clear what I mean, and I shall update the question.
def my_update_function(obj):
obj.x, obj.y = obj.x * obj.x, obj.y * obj.y
then in your class:
class my_class(object):
def __init__(self):
self.x = 2
self.y = 3
def simulate(self):
my_update_function(self)
