 index=0
 temp_list = []
 ran_name = random.randint(0, len(sub_list)-1)

 while len(temp_list) < input_2:
      ran_name=random.randint(0,len(sub_list)-1)
      temp_list.append(sub_list[ran_name])
      if(temp_list[index] == temp_list[index+1]):
          temp_list.pop(index)       
      else:
          index = index + 1
 for x in temp_list:
      print x
