How do I reset the value of variables in a loop? (Python 3.1.1)

How do I reset the value of variables in a loop? (Python 3.1.1)

When I run my code and get to the battle part of my game, I get random
values assigned to my characters attack, defense, damage and health.
However, after their first turn, they keep getting the same values and
they can't reset.
For example, the user's attack is a random number from 4 to 11. The
program "rolls" 5 and assigns it to the variable userAtk
userAtk = random.randint(4,11)
I assumed that everytime the loop ran, it would generate a new value. But
its not, and every time I print the variable its the same value it was
first assigned. Am I missing something?
Below is my code
import random
# VARIABLES
#
#
# This variable is the user's character name
userName = input("Brave warrior, what is your name? ")
# This variable is used in the input function to pause the game
enterNext = ("Press enter to continue...")
# This variable is used to format the user input prompt
# as well as the battle text
prompt = ">>>>> "
# This variable is used to add a new line to a string
newLine = "\n"
# This variable is used to display a message when the hero dies
heroDeadmsg = userName + " has fallen!"
# These variables represent the dragon's stats (HP, ATK & DEF)
dragonHp = 100
dragonAtk = random.randint(5,10)
dragonDef = random.randrange(8)
# These variables represent the user's stats (HP, ATK & DEF)
userHp = 90
userAtk = random.randint(4,11)
userDef = random.randrange(8)
# These variables calculate battle damage and HP
dragonDmg = (userAtk - dragonDef)
dragonHp -= dragonDmg
userDmg = (dragonAtk - userDef)
userHp -= userDmg
# This variable prints the options in the battle menu
battleMenu = """Attack (a) - Magic (m) - Item (i) - Run (r)"""
# This variable determines who goes first
cointoss = random.randint(0, 1)
# These variables print the actions in each turn
dragonAttack = \
prompt + "Crimson Dragon attacks you with " + str(dragonAtk) + " ATK!"\

# These variables show health during battle
printDragonhp = "Crismon Dragon has " + str(dragonHp) + " HP remaining!"
printUserhp = userName + " has " + str(userHp) + " HP remaining!"
# This variable simulates the results of a coin toss
