I added a descriptive title
I searched for other issues and couldn't find a solution or duplication
I already searched in Google and didn't find any good information or help

What happened?

`<html>
    <head>
      <link rel="stylesheet" href="https://pyscript.net/latest/pyscript.css" />
      <script defer src="https://pyscript.net/latest/pyscript.js"></script>
    </head>

  <body>
    <py-script src="example.py"></py-script>
  </body>
</html>`

adding the src argument to py-script tag causes pyscript to not execute code in local modules imported with the src tag. Manually writing code inside tags work normally though

This wasn't happening until today. Not exactly sure what is happening

What browsers are you seeing the problem on? (if applicable)

Edit: Checked the networking tab in dev tools from Firefox: it seems example.py, when fetched, somehow fetches index.html instead.

I can maybe also help but I'd rather someone to paste the code in some service like pastebin.com
Thanks

I did some more testing: it seems the issue arises when using Node to host a web server. Tested using python http.server, which works perfectly fine to start a web server, and referenced scripts will work just fine.
One issue though is that scripts inside child folders will not import properly, unsure if this is a limitation of web ?

Just opened up your file, it seems your python code is added in the same line. Python uses indentation so your code will not run. You will have to change it like:

<py-script>
    arr = [1,2,3,4]
    for i in arr: 
        print('Test' + i)
</py-script>
