In this example  the line do something else   will not be executed if do not continue is True  Control will return  instead  to whichever function called some function  def some function        if do not continue          return    implicitly  this is the same as saying  return None       do something else

A simple return statement will  stop  or return the function  in precise terms  it  returns  function execution to the point at which the function was called - the function is terminated without further action  That means you could have a number of places throughout your function where it might return  Like this  def player          do something here     check winner variable   check winner      check something      if check winner variable     1            return     second test variable   second test       if second test variable     1            return               let the computer do something     computer

def player game over       do something here     game over   check winner    Here we tell check winner to run and tell us what game over should be  either true or false     if not game over           computer game over    We are only going to do this if check winner comes back as False  def check winner         check something      here needs to be an if   then statement deciding if the game is over  return True if over  false if not     if score    100          return True     else          return False  def computer game over       do something here     game over   check winner    Here we tell check winner to run and tell us what game over should be  either true or false     if not game over          player game over   We are only going to do this if check winner comes back as False  game over   False    We need a variable to hold wether the game is over or not  we ll start it out being false  player game over     Start your loops  sending in the status of game over   Above is a pretty simple example    I made up a statement for check winner using score   100 to denote the game being over   You will want to use similar method of passing score into check winner  using game over   check winner score    Then you can create a score at the beginning of your program and pass it through to computer and player just like game over is being handled
