Well, mine is based on Python's half-open semantics: "up to" 1000 doesn't
include 1000, and the highest power of 2 less than 1000 is 512.
Perhaps you meant "up to and including 512".

Well, sure, if you want to do it the right way *wink*.
But seriously, no, that doesn't answer the OP's question. Look at his
original code (which I assume is C-like pseudo-code):
for x=1;x<=100;x+x:
print x
The loop variable i takes the values 1, 2, 4, 8, etc. That's what my code
does. If he was asking how to write the following in Python, your answer
would be appropriate:
for x=1;x<=100;x++:
print 2**x
