Get text from range on list

[mason]

I have a large file opened in a list. I need to get data from 275-349 from each line. How can I extract character position from the line location?

I'm not sure what You want to achieve, but it seems that You have to split that string in chars and then save in list, then take sublist with lines 275-349, then merge this new list into one variable will give You range of chars.
