In the interpreter you need an empty line to signal the end of an
indented code block.  (Code read from a file is scanned completely
before execution, so this hint isn't necessary there).  I think you'll
find that

while x.counter < 10:
    x.counter = x.counter * 2

print x.counter

works just fine. . .
