How do you create an instance of a class using a function in Python?
Question:
Something like this:
def new_instance(class_name):
return instance_of_class
E.g. if I had a Dog class, I could write d = new_instance(Dog) and d would now refer to a new Dog object.
Obviously I can write d = Dog() but I’d like to pass in the class as a parameter to the init method of another class.
Answers:
A class is just a named object like any other, so you can pass it as an argument to a function just as easily as you’d pass any other object.
def new_instance(cls):
return cls()
d = new_instance(Dog) # same as d = Dog()
