Hello
I read in a course that class UserList from module
collections can be used to create our own custom list
Example
>>> from collections import UserList
>>> class MyList(UserList):
... def head(self):
... return self.data[0]
... def queue(self):
... return self.data[1:]
...
>>> l = MyList([1, 2, 3])
>>> l.append(4)
>>> l
[1, 2, 3, 4]
>>> l.head()
1
>>> l.queue()
[2, 3, 4]
But I can do exactly the same without UserList
>>> class MyList(list):
def head(self):
return self[0]
def queue(self):
return self[1:]
>>> l = MyList([1, 2, 3])
>>> l.append(4)
>>> l
[1, 2, 3, 4]
>>> l.head()
1
>>> l.queue()
[2, 3, 4]
So what UserList is used for ?
