Okay
class A:
def __init__(self,x,y):
self.x = x
self.y = y
def save(self,fn):
f = open(fn,"w")
f.write(str(self.x)+ '\n') # convert to a string and add newline
f.write(str(self.y)+'\n')
return f # for child objects to use
def restore(self, fn):
f = open(fn)
self.x = int(f.readline()) # convert back to original type
self.y = int(f.readline())
return f
class B(A):
def __init__(self,x,y,z):
A.__init__(self,x,y)
self.z = z
def save(self,fn):
f = A.save(self,fn) # call parent save
f.write(str(self.z)+'\n')
return f # in case further children exist
def restore(self, fn):
f = A.restore(self,fn)
self.z = int(f.readline())
return f
In the class B, I'm not understanding the A.__init(self,x,y) part. So its
initializing the class A, and basically you can use the A class like normal?
Part im confused about is the self.z, does that belong to the class A or
class B? Else I think I'm understanding it correctly.
