Need some quick help with styling a text box

Hey all,
So I’ve got my compiler working, but now I’m working on a syntax highlighter for it, but it’s not quite working. It would be great If i could get help in, say, the next ten minutes.

Here’s my code for highlighting syntax:

import wx
import os
import sys
from string import *

Custom modules:

ID_TEXTBOX = 401

class MainWin(wx.Frame):
def init(self, parent, id, title):
wx.Frame.init(self, parent, id, title, size=(850, 450))
#Vars-
self.syntaxList =

    self.cVal = ""
    self.codePosition = -1
    self.blueColor = wx.Colour(0,0,175)
    self.blackColor = wx.Colour(0,0,0)
    self.greenColor = wx.Colour(0,200,0)
    #Menubar

    [self.sb](http://self.sb) = self.CreateStatusBar()
    self.code = wx.TextCtrl(self, ID_TEXTBOX, size=(200, 130), style=wx.TE_MULTILINE)
    self.code.SetFont(wx.Font(11, wx.FONTFAMILY_MODERN, wx.NORMAL, wx.NORMAL))

    self.Bind(wx.EVT_UPDATE_UI, self.SyntaxHighlight, id=ID_TEXTBOX)
    ####
    self.SetMinSize((300, 150))
    self.Centre()
    self.Show(True)
def dlg(self, text):
    amsg = wx.MessageDialog(None, str(text), "", wx.OK | wx.ICON_INFORMATION)

    amsg.ShowModal()
def SyntaxHighlight(self, event):
    self.codePosition = 0
    self.cVal = self.code.GetValue()
    for char in self.cVal:
        if char == "<":

            if "qt" not in self.syntaxList:
                self.syntaxList.append("lt")
                self.code.SetStyle(self.codePosition, self.codePosition + 1, wx.TextAttr(self.blueColor))

                self.dlg(self.codePosition)
        elif char == ">":
            if "qt" not in self.syntaxList:
                self.lastItem = len(self.syntaxList) - 1

                if self.syntaxList[self.lastItem] == "lt":
                    self.code.SetStyle(self.codePosition, self.codePosition + 1, wx.TextAttr(self.blackColor))
        elif char == "\"":

            self.syntaxList.append("qt")
            self.code.SetStyle(self.codePosition, self.codePosition + 1, wx.TextAttr(self.greenColor))
        self.codePosition += 1

class MyApp(wx.App):

def OnInit(self):
    MainWin(None, -1, 'Syntax Highlighting').Show()
    return True

app = MyApp()
app.MainLoop()
MainWin.Destroy(MainWin)

I know that you’ll probably suggest using stc, but I don’t have time to completely redesign my program.

Thanks in advance for any help.

A popup will keep coming up unless you delete line 40.
