Trying to print a display row-by-row, by adding rows together in a single, multi-line string

I am trying to print out a series of die that will display as below:

   ___     ___     ___     ___     ___
  |*  |   |*  |   |* *|   |*  |   |   |
  |   |   | * |   |* *|   | * |   | * |
  |  *|   |  *|   |* *|   |  *|   |   |
   ^^^     ^^^     ^^^     ^^^     ^^^

These die should represent the numbers that are produced when I 'roll the dice'. I have created a Die class and a Hand class, and they are produced below.

import random

class Die():

    def __init__(self):
        self.value = random.randint(1,6)

    def roll(self):
        self.value = random.randint(1,6)

    '''def __str__(self):
        return str(self.value)'''

---

import Die


class Hand:
    def __init__(self):
        self.L=[]
        for i in range(5):
            self.L.append(Die.Die()) #makes the number of dice



    def __str__(self):
        """converts hand to a string for printing"""
        return "{0},{1},{2},{3},{4}".format(self.L[0], self.L[1], self.L[2], self.L[3], self.L[4])

    def roll(self, keep):
        for i in range(5):
            if i+1 not in keep:
                self.L[i].roll()

The code given above will produce a list of numbers when the main file enters

h = hand.Hand()
h.roll() #this rolls the hand again
print(h)

Any ideas how I can get my results to print in the provided display style? It has been suggested that the best way to do it is to print three rows to construct all 5 dice. The most recent advice was "You have to build the entire display of dice row-by-row, then add the rows together in a single, multi-line string." I'm just not sure how to execute that.
