program

BEGIN PROGRAM PYTHON. 
import spss 

spss.StartDataStep() 
#current dataset 
datasetObj = spss.Dataset() 

varcount=spss.GetVariableCount() 
#populate a list or all the Variable Label 
varNameList= [spss.GetVariableLabel(i) for i in xrange(varcount) ] 
labellist=[] 
for i in xrange(varcount): 
  myLabel = spss.GetVariableLabel(i)
  newLabel = myLabel.capitalize() 
  spss.Submit(r""" rename labels (%s = %s) . """ %(myLabel, newLabel))

Answer 1

1) You have an error suggesting Submit cannot be used from within a Dataset.

2) VARIABLE LABEL is the correct command to relabel a variable.

Here is a simplified way of achieving the same:

get file="C:\Program Files\IBM\SPSS\Statistics\23\Samples\English\Employee data.sav".
begin program.
import spss, spssaux, spssdata
spss.Submit("set mprint on.")
vd=spssaux.VariableDict()
spss.Submit("VARIABLE LABEL %s." % ("\n".join(["%s '%s' " % (str(v), v.VariableLabel.capitalize())  for v in vd])))
spss.Submit("set mprint off.")
end program.
