Why does this piece of code work?

Lines 164 to 169 in 551de4b

	if not req[self.session_name]:
	await self._delete_key(key)
	if req[self.session_name].modified:

	return

Hello,

I was reading your code and stumbled upon the linked code lines.

There I don't understand why line 167 doesn't throw an error.
Because if if not req[self.session_name] evaluates to True how can there be a modified field?

It checks the value of req[self.session_name]'s modified field. learn python...

No reason to be toxic. I know Python very well.

I just don't make sense to me to access req[self.session_name].modified when not req[self.session_name] == True.
