1. 

strbottle="bottles of beer"

for i in range (99,0,-1) :
    if i == 1 :
        strbottle="bottle of beer"
    print i, strbottle, "on the wall,", i, strbottle

2.
the first value in range is where it starts counting, the second value
is where it stops and the third value is the increment
so if 0 is incremented by -1, it will never reach 10, from what I
understand of the python documentation on the "for" statement : the
sequence created is empty.
http://docs.python.org/reference/compound_stmts.html#the-for-statement
3.
I would like more :)
4.
list = ["one","two","three","four","five"]
for i in range(0,5) :
    print list[i]
