Help with this script

[Cheesywillie]

I am a Web designer but i am learning python. I am reading a tutorial and I came to the guess the number seciton could some1 answer me 2 questions about the game code:
How do i get a random Number to be generated?
How do i get the game to end after 20 guesses?

Here is my code thus far:
number = 78
guess = 0

while guess != number :
guess = input ("Guess a number: ")

if guess > number :
print "Too high"

elif guess < number :
print "Too low"

print "Just right"

Thanx for any Help

import random, sys
number = random.randint(1,100) # Random number between 1 and 100
guess = 0
failed = 0

while guess != number :
guess = input ("Guess a number: ")

if guess > number :
print "Too high"
failed = failed + 1
elif guess < number :
print "Too low"
failed = failed + 1
if failed == 20:
print "Sorry"
sys.exit()
print "Just right"
