Hi,
sorry for my ignorance, but after reading the Python tutorial on
python.org, I'm sort of, well surprised about the lack of OOP
capabilities in python. Honestly, I don't even see the point at all of
how OO actually works in Python.
For one, is there any good reason why I should ever inherit from a
class? ^^ There is no functionality to check if a subclass correctly
implements an inherited interface and polymorphism seems to be missing
in Python as well. I kind of can't imagine in which circumstances
inheritance in Python helps. For example:
class Base:
def foo(self): # I'd like to say that children must implement foo
pass
class Child(Base):
pass # works
Does inheritance in Python boil down to a mere code sharing?
And how do I formulate polymorphism in Python? Example:
class D1(Base):
def foo(self):
print "D1"
class D2(Base):
def foo(self):
print "D2"
obj = Base() # I want a base class reference which is polymorphic
if (<need D1>):
obj = D1()
else:
obj = D2()
I could as well leave the whole inheritance stuff out and the program
would still work (?).
Please give me hope that Python is still worth learning :-/
Regards,
Matthias
