Refeing to substring in list of strings

[Peter Kovalsky]

Hi,

I am new to Python and experienced a little problem with referencing 
lately. I have a list of strings that I have to modify. Thereofre I chose 
a for-construct (for index in range(len(mylist)):). I found certain 
substrings that i want to extract - but don' t know how to adress these 
substrings. I tried a
	mylist[index][lborder:rborder]
which won' r work for some reason - and I don' t know why. Can anybody 
help???

Thanx in advance,

Peter Kovalsky
