Python cluelessness with lists

Hi, I'm trying to transition from VBScript to Python and having some trouble understanding lists in Python.  What I'm trying to do is find all the comboboxes in a dialog and add them to a list.  Once...

    It looks like I figured it out.  I changed :

    combos = [(dlg.FindAllChildren(QtClassName,"OnOneComboBox",7))]

     

    to

     

    combos = list(dlg.FindAllChildren(QtClassName,"OnOneComboBox",7))

     

    Removing the brackets per your suggestion and adding "list" did the trick.  Now setting the index is working and I'm able to append to the list.

You said you are creating a list ...

So what do you suppose to do with combos[0].QComboBox_setCurrentIndex(1) ?

what the message saying is there is no attribute call "QComboBox_setCurrentIndex(1)" in lists class/object

 

what index are you going to set?   

 

for Iterate you can use combos[i] in for loop which iterate from 0 to len(combos)

 

to understand python lists read this and this

Hi, thanks for the reply.  I'm expecting combos[0] to return the combobox object at index zero in the combos list.  Provided that happens QComboBox_setCurrentIndex(1) will select the second item in the combobox.  

 

The problem is I'm not getting an object back with combos[0].  Instead of the combobox object I'm getting a "SafeArrayWrapper".  If I don't get the combobox back then QComboBox_setCurrentIndex(1) will obviously fail.

 

Also, I can't find any information in Python documentation regarding a "SafeArrayWrapper" object.  My assumption is SafeArrayWrapper is a SmartBear/TestComplete construct that doesn't exist natively in Python.  I could be wrong about that though.
