I believe that the usage of 'in <blah>' converts it into a set (or
set-like) object so probably that is the same as set(list(set())).
Again what do you mean by "stuck"? Does it error or do you just wait?
Can you provide a small sample script (including sample sCommonFeatures and FD)
?
What version of Python / operating system?

It would be more efficient to do the following
def getValue(mydict, keys):
A=[]
for i in keys:
A.append( mydict[i] )
return A
