Python: What is the point of `import X as X` where X the same?
Question:
In aiohttp I found many statements with import X as X. Why it was done like that?
Answers:
I did not know the answer, but the history of the linked source file revealed it.
The construct from SOMEWHERE import X as X (with the same X) is required to silence a warning from mypy --strict about not re-exported module. AFAIK, adding the as X to import X has no effect to the program itself.
mypy is an optional static type analyzer and apparently the developers decided to use it and to use it in the strict mode.
