Evaluating strin composed of multiple parts?

[Maurice van de Rijzen]

Dear all,
I'm using numpy.
In numpy one can take a part of a multi array just as in matlab.

  	partArray=totalArray[1:10,1;10,:,:,:

Now I've encounterd the following problem.
I'm using the followoing code:

class SubDataMatrix_5D:
	def SetInput(self,DataInput):
		self.DataInput=DataInput
	def SetDimensions(self,dim1,dim2,dim3,dim4,dim5):
		self.Dim1=dim1
		self.Dim2=dim2
		self.Dim3=dim3
		self.Dim4=dim4
		self.Dim5=dim5
	def CreateSubMatrix(self):
self.Sub=self.DataInput[eval(self.Dim1),eval...
		(self.Dim2),eval(self.Dim3),eval(self.Dim4),...
		eval(self.Dim5)]
	def GetOutput(self):
		return self.SubMatrix

temp2=SubDataMatrix_5D()
temp2.SetInput(temp.GetOutput())
temp2.SetDimensions("1:10","1:10","1:10","1:2","1:2")
temp2.CreateSubMatrix()


Doing this gives the following error:

self.SubMatrix=self.DataInput[eval(self.Dim1),eval(self.Dim2),eval(self.Dim3

),eval(self.Dim4),eval(self.Dim5)]
   File "<string>", line 1
     1:10
      ^

I know there goed something wrong with the strings but I have no clue of
how to solve it.
Preferrebly I would like to set the dimensions as follows:


temp2.SetDimensions(1:10,1:10,1:10,1:2,1:2)

Can someone please help me?
