python - Creating a slot machine for school -

i'm programming slot machine school , cannot machine re-run once finished. relatively new , honest feedback. how can program re-run? code i'm trying with. i've modified code this.

import random  import sys   print "hi there user, welcome amazing poker machine simulator." print "your opening account has in $1000." print "to win jackpot, 3 leprachauns must in row." print "enter yes or no when prompted finish or continue program."  balance = 1000 balance == int(balance) winnings = 0 winnings == int(winnings)  symbols = ["leprachaun", "goldbar", "pyramid", "blackcat"]  # subroutines:  checking bet input , amount def betcheck(betamount):     if betamount.isdigit() == true:         betamount == int(betamount)         rightbet = true     else:          rightbet = false         print "please enter whole number, no decimals , bet on or below balance."     return rightbet  # limiting bet def betlimit(betamount):     if betamount > balance == false:         goodlimit = false         print "that bet high!"     else:         goodlimit = true     return goodlimit  # checking 'ask' input play machine. def askinputcheck(answerinput):     if answerinput == "yes" or answerinput == "yes" or answerinput == "y" or answerinput == "no" or answerinput == "no" or answerinput == "n":         rightanswerinput = true     else:         rightanswerinput = false         print "this incorrect input, please type appropriate answer in."     return rightanswerinput  # printing , sorting symbols. def spinning(reels):     global balance     if reelone == "leprachaun" , reeltwo == "leprachaun" , reelthree == "leprachaun":         winnings = int(betamount) + int(balance) * 1000         print "you won jackpot! congragulations! how account contains $", winnings     elif reelone == "goldbar" , reeltwo == "goldbar" , reelthree == "goldbar":         winnings = int(betamount) + int(balance) * 500         print "you won considerable return! awesome! balance , wins $", winnings     elif reelone == "pyramid" , reeltwo == "pyramid" , reelthree == "pyramid":         winnings = int(betamount) + int(balance) * 250         print "you won return! conspiracy! of money total $", winnings     elif reelone == "blackcat" , reeltwo == "blackcat" , reelthree == "blackcat":         winnings = int(balance) - int(betamount)         print "unfortunately didn't win anything, bad luck! rewards $", winnings     else:         winnings = int(balance) - int(betamount)         print "bad luck! maybe next time you'll win! remaining cash $", winnings         print winnings     return reels  # if have no money def rebalance(balance):             while balance == 0 == true , startagain == true:         unbalance = true         balance = 1000         print "you ran out of money, here $1000"     else:         unbalance = false         print "you still have money."         return unbalance  # leads bet input check.  validbet = false while validbet == false:     betamount = raw_input("please enter amount wish bet: ")     validbet = betcheck(betamount)  betamount == int(betamount)  # leads betlimit appropriatelimit = betlimit(betamount)  # randomsymbolgen + 3 reels reelone = random.sample(["leprachaun", "goldbar", "goldbar", "pyramid", "pyramid", "pyramid", "blackcat", "blackcat", "blackcat", "blackcat"],1) reeltwo = random.sample(["leprachaun", "goldbar", "goldbar", "pyramid", "pyramid", "pyramid", "blackcat", "blackcat", "blackcat", "blackcat"],1) reelthree = random.sample(["leprachaun", "goldbar", "goldbar", "pyramid", "pyramid", "pyramid", "blackcat", "blackcat", "blackcat", "blackcat"],1)  reels = [reelone, reeltwo, reelthree]  slotspin = spinning(reels)  print reels  # leads ask input check.

having spare time, have modified code.
code supplied riddled small coding , logical errors. best running diff command between original code , code below, see many differences , there no guarantee bug free either.
hope you're not planning on fleecing fellow pupils, rebalance routine twisted work of future loan-shark. ;)
