DONE! Thank you all! I will keep studying it till i figure it our completely

text_list = []
user_data=input()
while user_data!="end" and user_data!="END":
  met_data_list=[0,0,0,0,0,0,0,0,0,0,0]

  for char in user_data:
    if char.isdigit():
        idchar=int(char)
        met_data_list[idchar] += 1
    else:
        met_data_list[10] += 1

  for i in range(len(met_data_list)):
    if met_data_list[i]>9:
     met_data_list.pop(i)
     met_data_list.insert(i,"*")
       
    
    

  print ("{}{}{}{}{}{}{}{}{}{}{}".format(met_data_list[0],met_data_list[1],met_data_list[2],met_data_list[3],met_data_list[4],met_data_list[5],met_data_list[6],met_data_list[7],met_data_list[8],met_data_list[9],met_data_list[10]))
  #print(''.join(text_list))
  user_data=input()
