[Tutor] __init__ doesn't seem to be running

[Cameron Macleod]

Hello everyone, I'm using Python 3.3 and am trying to write a simple to-do
list program. I have a class which runs pretty much everything called todo
and the __init__ method doesn't seem to be running.

class todo():
    def __init__(self):
        tasks = []

    def writeTask(todoList):
        name = input("Please enter the task > ")
        desc = input("Please enter a short description (optional) > ")
        while True:
            try:
                imp = int(input("How important is this task? 1-100 > "))
                break
            except TypeError:
                imp = int(input("How important is this task? 1-100 > "))
        if imp > 100:
            imp = 100
        elif imp < 1:
            imp = 1
        todoList.write("\"" + name + "\",\"" + desc + "\",\"" + str(imp) +
"\"")
        print("Task written!")
    try:
        todoList = open('todo.txt', 'r+')
    except IOError:
        todoList = open('todo.txt', 'w')
    for line in todoList:
        tasks.append(line.strip())
    writeTask(todoList)
    todoList.close()

main = todo()

Whenever I run this, I get the error:

Traceback (most recent call last):
  File "C:\Python33\todo.py", line 8, in <module>
    class todo():
  File "C:\Python33\todo.py", line 34, in todo
    tasks.append(line.strip())
NameError: name 'tasks' is not defined

Indicating that __init__ hasn't run since that is the initialization for
tasks. I had always understood that __init__ was the equivalent of a
constructor, and should be run at the instantiation of any class.

Any help would be much appreciated,
Cameron
