How to manipulate data in a list while rely on references to it with a dictionary?

[Jory R Ferrell]

"while relying on...." :P

Anyways...

Basically I am starting off with a user defined number of variables. For each object needed, I 'assign a variable'
by using the key of a dictionary. How do I use object references, append to list and what not, if i am relying on a dictionary to call it?

dict = {1:['a','b','c','d'], 2:classObj1, 3:classObj2}

dict[1].append('e','f','g','h','i')
dict[2].classObj2Method()
dict[3].classObj3Method(2, myData)
print(dict[3].name)

Your problem is list method append() accepts one argument. You are passing 5 arguments. Use method extend() instead.

>>> p1 = Pt3D(1,2,3)
>>> p1
Pt3D(1.000000, 2.000000, 3.000000)
>>> p2 = Pt3D(4,5,6)
>>> dd = {1:[1,2,3,4,5,6], 2:p1, 3:p2}
>>> dd
{1: [1, 2, 3, 4, 5, 6], 2: Pt3D(1.000000, 2.000000, 3.000000), 3: Pt3D(4.000000, 5.000000, 6.000000)}
>>> dd[1].extend([7,8,9,10])
>>> dd
{1: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10], 2: Pt3D(1.000000, 2.000000, 3.000000), 3: Pt3D(4.000000, 5.000000, 6.000000)}
>>> dd[2].cross(dd[3])
Pt3D(-3.000000, 6.000000, -3.000000)
>>>
