CGTalk - random connection

G.H.O.S.T

Hello everyone,
I´m trying to write a python script that will randomly connect attributes of different objects.
Here is what I have:
connections = e.g. connect 3 pCylinders connect to 10 polySpheres(that's why there is "Sph" in partition function.
inputNodes = []
outputNodes = []
selNodes = cm.ls(selection=True)
for nodes in selNodes:
if nodes.partition("Sph")[1] == "Sph":
inputNodes.append(nodes)
if nodes.partition("Sph")[1] != "Sph":
outputNodes.append(nodes)

for node in range(len(inputNodes)):
dividedNum = (len(inputNodes)-1)
i = random.randint(0,dividedNum)
dividedNum = (len(outputNodes)-1)
o = random.randint(0,dividedNum)

if cm.isConnected(outputNodes[o]+".rotateX", inputNodes[i]+".rotateX") == 1:

cm.disconnectAttr(outputNodes[o]+".rotateX", inputNodes[i]+".rotateX")

cm.connectAttr(outputNodes[o]+".rotateX", inputNodes[i]+".rotateX")

the problem is that when code detects connection between objects, instead of disconnect the attributes and then reconnect them it prints error , that attributes are already connected.
This means that somewhere I have and error. But where?

your code has lost all formatting so it's a little hard to say where there is or isn't certain errors, however, rather than disconnect if connected, why don't you just connect if not connected?

Thank you Nathan, but still got the same error. In "has lost formatting" did you mean absence of indentation or the code is not readable because I wrote it very bad?
Anyway, can you advice how to write this kind of code? Not command and/or code, just paragraphs.
There is two group of objects. Group A and group B.
Group A have multiple members. The members of the group A in the name have some common string. e.g. pSphere1, pSphere2, pSphere3 etc
Group B have less members and different names.
After I get a list of this objects I might do separate them in different lists. Then I loop through each member of group A and generate a random index number for members of that groups. Them I check if member[index]'s attr of group A have connection with member[index]'s attr of group B. If it not then connect this two group's attribute.
Is this correct?
