  I want to generate all size 2 strings from a list of size 1 string
  e.g featureList = gives
  I wrote this code
  def genC(featureList): for i in range(0,len(featureList) - 1,1): for k in range(1,len(featureList) - 1,1): if i+k <= len(featureList)-1: colocn = featureList[i] + featureList[i+k] prunedK.append(colocn) continue continue return prunedK
  However this does not give me all the required strings.It doesnt give me that 2 length string for which i=0 and k=len(featureList) -1.Any ideas why this is happening(even though the if condition is satisfied)??
