"Arguably" is an understatement.

I would consider it two concepts: (1) you're looping over the values
range(0, 10) and (2) skipping over values in range(2, 8).
Until we reach the bottom of the block, we can't be sure that the
condition isn't
if i not in range(2, 8): ...
else: ...
which by the way suggests that this suggested syntax would be ambiguous:
for i in seq: if condition:
block
else:
block
Does the `else` partner the `for` or the `if`?
