First of all, I tried this:
http://www.python-forum.org/pythonforum/viewtopic.php?f=3&t=22068
Then, I decided not, so I will try this:
Code:
def token2bin(inp):
i = 0
maxtokenlenght = 16
while (i<len(inp)):
out = ''
out1 = -1
out2 = -1
for a in range (maxtokenlenght, 0, -1):
k = inp[i:i+a]
try:
if tr[k] == [] or out == '':
pass
else:
out = k
j = tr[k]
if(j<999):
out1 = j
out2 = -1
else:
out1 = int (j / 1000)
out2 = j - 1000 * out1
except:
pass
if (out1 == -1):
pass
else:
i += len(out)
if (out2 == -1):
o *= str(out1)
else:
o *= str(out1) * str(out2)
return o
print token2bin("Disp ")
And need to make a dictionary named 'tr', but need to learn dictionaries too :S
Well, the alternatives that they're offering are all based around the concept that searching for "D" in the string 'Disp D' will yield two match, not one, which is incorrect for tokenization. Hopefully the second, which appears to be your Pythonization of my code, will do the trick.

Yes, the first one has another problem too. It can only find one of each as it is right now, so the code:
Code: Disp "Hello World!"
has two quotation marks, it would only detect one :S

Sure, but unless you know PHP you wouldn't necessarily know that a PHP array is not what most languages call an array. When someone says "array", they often mean something like a list. That isn't what Kerm meant, though.

Ooh, so that's confusing, for me an array is a list and in PHP it's not a list? Wow!
Anyways, what I need is a dictionary which look quite easy to do in Python

It's a good thought, but personally I'm not sure how useful regex would be in this case. The regex match for the TI token set would be truly enormous.
Well, I found something... It looks like someone has already done it in python and the code is here:

Yup, here's the meat of the recompiler, which is very similar to what I do:
Code: while readFile.tell() <= fileLength: # Ignore the last 2 bytes (checksum)
readLen = 1 + fileLength - readFile.tell()
readLen = min([maxKeyLen, readLen])
current = readFile.read(readLen)
# Try each possible key for the next few characters
while (readLen > 1 and not tDict.has_key(current)):
readFile.seek(-1*readLen, 1)
readLen -= 1
current = readFile.read(readLen)
if tDict.has_key(current):
writeBuffer.append(tDict[current])
if (current == "\n") or (current == "\r\n"):
lineNum += 1
# count line numbers
elif current == "&":
# The ampersand is the escape sequence character.
# If we got here, then:
# A) This is the escape sequence &@, indicating that
# the next character should be translated literally.
readFile.seek(-1, 1)
current = readFile.read(2)
if current == "&@":
current = readFile.read(1)
writeBuffer.append(current)
# B) This is an invalid escape sequence. Let's announce that.
else:
print "%s is an invalid escape sequence on line %s" % (current, lineNum)
writeBuffer.append("ERROR %s" % current)
else:
# A character is unreadable!
print "%s not found on line &s" % (current, lineNum)
writeBuffer.append("ERROR %s" % current)
programMeat="".join(writeBuffer)

The seek command is used, along with a few others :S
Is that a problem?
I'd be happy to explain any commands that you don't understand.

Thanks much!
I don't know how seek works.
I tried running the program but it tells me non-ascii characters :S

"seek() basically goes to a specific byte in a file, assuming that there's an implicit pointer into said file. Each time you read n bytes from the file, the pointer moves forward by n characters/bytes. Most programming languages having rewind() and/or seek() to move that pointer to an arbitrary location."
Thanks. You had any luck running it?

Can't say I've bothered trying, personally. 
SourceCoder is all the converter that I need, plus I have a lot of stuff going on in my life atm.

looooooooooool.
I have to try it with an older version of Python.
Which file does it say has the non-ASCII characters? Also, which version of python are you running; I assume 3.x?

Version 2.6, of course
The dictionary file gives me it :S
