Something's broken with ajax module in Brython 3.11.0. Importing ajax raises this error in console (chrome and safari):

Traceback (most recent call last):
File "http://server.local:8001/results.py", line 13, in <module>
from browser import ajax
ModuleNotFoundError: No module named 'browser.ajax'

Test code

<html>

<head>

</script>

</head>

import browser

from browser import ajax

</script>

</body>

</html>

You have to load also the stdlib.

Have a look here:
https://www.brython.info/static_doc/en/install.html

Let us know if it solves the issue.

Thanks kiko. That seemed to fix it.

It's very strange because I have an old project that doesn't use stdlib and ajax import works just fine. Also, I thought any "from browser import X" items were part of the base distribution. If it's in the stdlib why not just "import ajax" instead. Oh well.

In the past there was a brython_dist.js
(https://www.jsdelivr.com/package/npm/brython?tab=files&version=3.2.6)
that merged brython+stdlib. Maybe you were using this.

The brython specific modules are included within browser and
javascript modules so ajax is included within browser. It is just an
implementation detail.

It's possible. I haven't made a new brython project from scratch in years. Just add to existing projects / environments.

From an implementation standpoint, sure. Any module can load from anywhere, doesn't matter.

From a user standpoint, importing ajax "from browser" makes it appear to be part of the base distribution. You wouldn't put window or console or document in stdlib. Those are basic features that every web app expects to be available at a minimum. Same with ajax. Very surprised that's not the case here.

Anyway it works, so thanks!
