Class method: Used to access or modify the class state. In method implementation, if we use onlyclass variables, then such type of methods we should declare as a class method. The class method has aclsparameter which refers to the class. Static method: It is a general utility method that ...
classes partake of the dynamic nature of Python: they are created at runtime, and can be modifi...
