Solution: By using lambda functions in python(Check your PL’s manual for anything similar), you would be able to create on-the-fly functions that returns your bindings with the extra parameters/arguments you want to pass.

Example 1: Passing an argument to a wx Button Event

btn = wx.Button(self, 10, “Button”, (10, 10))
self.Bind(wx.EVT_BUTTON, lambda event: self.OnClick(event, ‘passthis’))

def OnClick(self, event, somearg):
   print somearg

Example 2: Passing an argument to Pyhook’s HookManager.KeyUp Event

hook = pyHook.HookManager()
hook.KeyUp = lambda event: OnKeyboardEvent(event, ‘Pass Me.’)
hm.HookKeyboard()

def OnKeyboardEvent(event, myarg)
  print myarg

That’s It!

Solution: No Problem! Use the len (abbrev. for length) function:

import re
>>> regex = re.compile(r”your pattern here…*”)
>>> match = regex.findall(”the contents…”)
>>> len(match)
10

That’s It!

On a side note, you can also use len to count the number of characters in a string.

>>> text = “All your base…”
>>> len(text)
16
