Random D20 number generator I'm teaching myself code using Zed Shaw's Learn Python The Hard Way, and I got bored during one of the memorization lessons so I thought I would make a random D20 number generator for when I play RPGS. 

How can I make this code better? Is there anything stupid I'm doing? 

import random

name = raw_input('Please Type in your name &gt; ')

print "\nHello %s &amp; welcome to the Random D20 Number Generator by Ray Weiss.\n" % (name)

first_number = random.randint(1, 20)

print first_number

prompt = ("""
Do you need another number? Please type yes or no.
""")

answer = raw_input(prompt)

while answer == "yes":
    print random.randint(1, 20)
    answer = raw_input(prompt)

if answer == "no":
print "\nThank you %s for using the D20 RNG by Ray Weiss! Goodbye!\n" % (name)


Eventually I would love to add functionality to have it ask you what kind and how many dice you want to role, but for now a review of what I've done so far would really help.
Here's my take:

from random import randint
name = raw_input('Please Type in your name &gt; ')

print """
Hello {} &amp; welcome to the Random Number Generator by Ray Weiss.
""".format(name)
upper = int(raw_input('Enter the upper limit &gt; '))
n = int(raw_input("How many D{} you'd like to roll? ".format(upper)))

for _ in xrange(n):
    print randint(1, upper)
print """
Thank you {} for using the D{} RNG by Ray Weiss! Goodbye!
""".format(name, upper)


Changes as compared to your version:


directly import randint because it's the only function you use in random;
use the new string formatting method (str.format);
take the upper bound from user instead of hard-coding 20;
take the number of rolls from user instead of repeatedly asking if that's enough;
use a loop to make the repetition actually work. The self-repeating code asking the user if we should continue is now gone.
