When I call the displaycount method of my list subclass, I get no output. What is the problem?
class mylist(list):
def _init_(self,name,age):
list._init_(self, years)
self.name = name;
self.age = age;
def displaycount(self):
print "total employees %d" % self.name
emp1 = mylist('lada', 20)
emp1.displaycount()
You have a few problems:
'_init_' != '__init__';years defined?self.name is a string, what do you think "total employees %d" % self.name will do?displaycount currently recursively calls itself on a new mylist instance.Perhaps you mean:
class mylist(list):
def __init__(self, name, age):
super(mylist, self).__init__()
self.name = name
self.age = age
def displaycount(self):
print "total employees {0}".format(self.age)
emp1 = mylist('lada', 20)
emp1.displaycount()
list.__init__(self) - two underscores, and you still haven't defined years
mylistclass for it's__init__method to be called. You'll also have to call thedisplaycountand perhaps fix your indentationdisplaycountonly inside itself, which might cause infinite recursion if you actually call it once from outside ...displaycountis nested inside_init_(which has the wrong number of underscores!)
