Python: NameError for no apparent reason? -

 random import random   def computer():  computer = 0  while computer < 21:   val = int(random()*10)+1   if (computer + val) > 21:    break   else:    computer += val  print "ich habe ", computer, "!"  return computer       def player():  player = 0  loss = 0  while player < 21:                 hval = int(random()*10)+1                 print "du hast ", hval, "...\nnoch eine mit y..."                 if raw_input == "y":                         player += hval                         if player > 21:                                 print "du hast verloren!"                                 loss = 1                                 break                         else:                                 continue                 else:                         player += hval                         break         return player         return loss      if __name__ == "__main__":         player()         if loss == 1: #this nameerror.                 pass         else:                 computer()                 if computer > player:                         print "ich habe gewonnen!"                 else:                         print "du hast gewonnen" 

i returned loss in player() don't know why keep getting nameerror.

let's clean mess , see errors are:

from random import random # tip, check out randint (the function in random module)  def computer():     computer = 0     while computer < 21:         val = int(random()*10)+1 # please use whitespace around operators          if (computer + val) > 21:             break          else:             computer += val      print "ich habe ", computer, "!"     return computer  def player():     player = 0     loss = 0      while player < 21:         hval = int(random()*10)+1 # again, whitespace improves readability         print "du hast ", hval, "...\nnoch eine mit y..."          if raw_input == "y": # raw_input function (hint need call function)                              # you're comparing object against string                              # yield false, therefore player                              # never gets chance enter number              # never gets executed             player += hval             if player > 21:                 print "du hast verloren!"                 loss = 1                 break              else:                 continue          # gets executed         else:             player += hval             break      return player # returns value of player     return loss # never reached, dead code, return above has left function  if __name__ == "__main__":     player() # returns integer, doesn't assign name      if loss == 1: # loss not defined in scope         pass      else:         computer() # again, doesn't assign returned value      if computer > player: # if reached, fail yet again                           # no name error time, you're comparing function object                           # against player object, (at least in cpython)                           # compare memory addresses          print "ich habe gewonnen!"      else:         print "du hast gewonnen" 

now know errors, it's fix them :)

but want note indentation real mess, ranging 1 space 16 per indent.
in python indentation essential part of syntax, no means tolerable.

please read pep8 on how style code.
