Ah, I see -- this is a really good point, thanks for bringing it up. You're right, one can not arbitrarily increase scope in Python. The most common way I've seen of demarcating this kind of structure is actually using a blank line. For example, the code would instead look more like: c = create_context() for foo in foos: do_something(foo, c) do_other_thing(foo, c) accumulate(foos, c) do_other_stuff One could also throw the separate stuff into a new function.
