def write(v):
v.write()
write(i) # i is MySub instance
|
| In C++/Java we would declare v as a MyBase reference and rely on i.write() as calling the virtual function write in MySub |
| The same works in Python, but we do not need inheritance and virtual functions here: v.write() will work for any object v that has a callable attribute write that takes no arguments |
| Object-orientation in C++/Java for parameterizing types is not needed in Python since variables are not declared with types |
