[Tutor] wxPython buttons in a loop

[adam]

I'm trying to create a wxPython app which goes through a loop and produces
a wxBitmapButton for every letter of the alphabet.

However, when I run the code below, I get three a's duplicated, although
the debugging print statements show that 'alphabet_graphics/b.bmp' has
also been called.

Is this problem related to bmp being a constant here? If so, how would I
go about overwriting it? I tried creating a list of 'bmp' but I always got
IndexError: list index out of range
when I ran it.

Any help gratefully appreciated.

alphabet = ['a','b','c']
		alphabetgraphics = ['a.bmp', 'b.bmp', 'c.bmp']
		#bmp =[] # Not currently used
		#grafic = [] # Not currently used

		for i in range(len(alphabet)):
			print alphabetgraphics[i] # Debug tool.
			bmp = wxBitmap('alphabet_graphics/' + alphabetgraphics[i],
wxBITMAP_TYPE_BMP)
			self.grafic =wxBitmapButton(self,30,bmp,wxPoint(160,20),
wxSize(bmp.GetWidth()+10,bmp.GetHeight()+10))
			self.sizer2.Add(self.grafic,1,wxEXPAND)
			print bmp # Debug tool.
