I have a very simple problem here. I want to achieve the following VB script Code in Python:-

dim objSfact 
dim objOrun 
dim mystep 
Set objOrun = QCutil.CurrentRun 
Set objSfact = objOrun.StepFactory 
Set att = objSfact.AddItem(null) 
att.name = aStepname 
att.post 
Set steplist = objSfact.NewList("SELECT * FROM Step 
WHERE 
ST_STEP_NAME='" & aStepname & "'") 
For each mystep in steplist mystep.Status = aStatus myStep.Field("ST_DESCRIPTION") = aDesc myStep.Field("ST_EXPECTED") = aExpected mystep.Field("ST_ACTUAL") = aActual If mystep.Status = "Failed" then objOrun.Status = "Failed" end if mystep.Post 
Next 
Set objSfact = Nothing 
Set objOrun = Nothing 

Particularly, I cannot do this in Python - mystep.Field("ST_ACTUAL") = aActual ; because I get the following error- "SyntaxError: can't assign to function call" Any help? Thanks, Amit

UPDATES: Please, the python script can be found here... Adding testcase results to Quality Center Run from a outside Python Script

In Python () represent calls to functions, while [] represent indexing and mapping.
