That is IMO not an endmarker, or at least not an explicit one.
If it was explicit you couldn't be confused between thinking
a certain code was dedented three or four times.

But I thought python wanted to provide as much as possible only
one correct way to do things.

It is not about my choice. I'll get by whatever the outcome. Just as I
in general write proper indented code even in languages that don't
enforce it. I just find it odd that a language that tries to enforce
readablity does't include end markers, who IMO increase readability.
