COPYING A LIST +D=FJAH % Subscripts 43 44 CHAPTER 7. SUBSCRIPTS Each list item occupies a specic position. Positions are numbered starting at 0 and each item can be referenced by it's position number (called the "index"). You subscript a list object by specifying the index number in square brackets. list_object [index] For convenience, Python allows both positive and negative subscripts. Normal Python subscripts (like subscripts in most other languages) start at 0 and are relative to the start of the list.
The slice operator species a range of list indexes. Items from this range are copied from the original list into a new list object. x ranges. Slice Syntax list_object [start : end : stride] The slice syntax is similar to the subscripting syntax (they both use square brackets). A slice is specied with 3 parameters, all of which are optional. The parameters are separated by a ":" character. start end the start of the range to copy the end of the range to copy stride the direction in which copying takes place and the number of items to skip over REMEMBER: the end value is always excluded from the result Quick Copy Using the default values for start, end, and stride will copy every item in the list.
The step can be positive or negative. If step > 0, numbers are produced by counting up from start to stop (not including stop). If step < 0, numbers are produced by counting down from start to stop (not including stop). The step can also skip over values. If step = 2, the output contains every 2nd value, if step = 3, the output contains every 3rd value, etc. x) functions return iterator objects. Use the list() function to turn the iteration into an actual list. x = list(xrange(5)) Examples Range range(10) range(5, 10) range(10 ,0) range(10, 0, -1) range(10, 0, -2) Produces [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] start defaults to 0 [5, 6, 7, 8, 9]  there is no way to get from 10 to 0 by counting KF [10, 9, 8, 7, 6, 5, 4, 3, 2, 1] [10, 8, 6, 4, 2] range counts down by 2's REMEMBER: the stop value is always excluded from the output +D=FJAH ' Range Slices 49 50 CHAPTER 9.
