What is the difference between a class variable and an instance variable in Python?
There is no difference in Python; they are treated the same way.
Class variables can only be integers, while instance variables can be any type.
Instance variables are declared outside any method, while class variables are declared within methods.
Class variables are shared across all instances of a class, while instance variables are specific to each object.
Class variables are shared across all instances of a class, while instance variables are specific to each object.
How do you correctly access an instance variable name within a method of the same class in Python?
def method_name(self):
return self.name
def method_name(name):
return name
def method_name():
return name
def method_name(self):
return name.self
def method_name(self):
return self.name
