Unfinished brainfrak

[microfarad]

Here I have an unfinished brainfuck interpreter, written in Python, and an unfinished program written in brainfuck...

import sys
class brainfuck():
   def __init__(self,ProgOut,ProgIn,ProgMsg):
       self.ProgOut = ProgOut
       self.ProgIn = ProgIn
       self.ProgMsg = ProgMsg
       self.Prog = ''
       self.Data = {}
       self.DP = 0
       self.IP = 0
   def step(self):
       try:
           Inst = self.Prog[self.IP]
       except:
           self.ProgMsg(1)
       try:
           test = self.Data[self.DP]
       except:
           self.Data[self.DP] = 0
       if (Inst == '>'):
           self.DP = self.DP+1
       elif (Inst == '<'):
           self.DP = self.DP-1
       elif (Inst == '+'):
           self.Data[self.DP] = self.Data[self.DP]+1
       elif (Inst == '-'):
           self.Data[self.DP] = self.Data[self.DP]-1
       elif (Inst == '.'):
           self.ProgOut(self.Data[self.DP])
       elif (Inst == ','):
           self.Data[self.DP] = self.ProgIn()
       elif (Inst == '['):
           try:
               if (self.Data[self.DP] != 0):
                   self.IP = self.IP
               else:
                   self.counter = 1
                   while (self.counter != 0):
                       self.IP = self.IP+1
                       if (self.Prog[self.IP] == '['):
                           self.counter = self.counter+1
                       elif (self.Prog[self.IP] == ']'):
                           self.counter = self.counter-1
           except:
               self.ProgMsg(2)
       elif (Inst == ']'):
           try:
               if (self.Data[self.DP] == 0):
                   self.IP = self.IP
               else:
                   self.counter = 1
                   while (self.counter != 0):
                       self.IP = self.IP-1
                       if (self.Prog[self.IP] == ']'):
                           self.counter = self.counter+1
                       elif (self.Prog[self.IP] == '['):
                           self.counter = self.counter-1
           except:
                   self.ProgMsg(3)
       else:
           self.ProgMsg(4)
       self.IP = self.IP+1

def ConsoleOut(Msg):
   sys.stdout.write(chr(Msg))
def ConsoleIn():
   char = ord(input(''))
   print(str(char))
   return char
def ConsoleMsg(Msg):
   print(str(Msg))
   Go = False

while True:
   Go = True
   BF = brainfuck(ConsoleOut,ConsoleIn,ConsoleMsg)
   BF.Prog = input('Program: ')
   steps = 8000
   while ((steps >= 0) and Go):
       try:
           BF.step()
           top = BF.IP+3-1
           if (top > (len(BF.Prog)-1)):
               top = len(BF.Prog)-1
           bottom = BF.IP-3-1
           if (bottom < 0):
               bottom = 0
           #(repr(BF.Data)+'\t'+repr(BF.DP)+'\t'+BF.Prog[bottom:BF.IP-1]+' '+BF.Prog[BF.IP-1]+' '+BF.Prog[BF.IP:top+1])
       except:
           print('Error')
           Go = False
       steps = steps - 1

SINCE STUPID PROBOARDS TOOK OUT ALL OF THE INDENTS!!!

I have to double post with this attached file...

Edit: The input and output do not yet comply with how they should be. This is a very rough version.

I get MANY MANY syntax errors just to let you know.
and I don't know ANY of your BASH: commands.

just to let you know.

[microfarad]

I don't any syntax errors. And this has nothing to do with bash. You're obviously doing something fundamental very wrong. Be sure to open the file I attached in IDLE with Python 3.1.3 installed on your computer.

so I see... my computer likes python to run from terminal! sorry for false alarm!

Qwerty, brainfuck is the name of a perfectly legitimate esoteric language. I'm not the happiest that it was named brainfuck either, but change it back dude. Besides, it would be brainfrack, not brainfrak. At least censor correctly...

[Qwerty]

It is also a swear and as such will be blocked from the title like any other swear would be. It doesn't get special privileges just because it's also the name of a programming language. Just be lucky I'm not censoring it completely, or editing the rest of the post. There is no "correct" way to censor, and as brainfrak contains the same number of letters, so I consider it to be more correct than brainfrack, which is quite frankly awkward to read.
