How to use pyodide function more one times

I want run funcion to stemm each row of a table. I want do it after of HTML code is loaded, I try this

<body>
    <script
      type="text/javascript"
      src="https://cdn.jsdelivr.net/pyodide/dev/full/pyodide.js"
    ></script>
    <script type="text/javascript">
        
      async function main(kw) {
        let pyodide = await loadPyodide({
          indexURL: "https://cdn.jsdelivr.net/pyodide/dev/full/",
        });
        
        pyodide.globals.set("mikw", kw);     
        await pyodide.loadPackage("micropip");
        await pyodide.runPythonAsync(`
            
        import micropip
        import js
        await micropip.install('snowballstemmer')
        import snowballstemmer
        stemmer = snowballstemmer.stemmer('english')
        
        div = js.document.createElement("div")
        div.innerHTML = stemmer.stemWords('Hello this my default text '.split())
        js.document.body.prepend(div)
        varP = js.document.getElementById('origen').textContent
        print(varP)
        salida = stemmer.stemWords(varP.split())
        print(salida)
        divSalida = js.document.createElement("div")
        div.innerHTML =salida
        salida = stemmer.stemWords(mikw.split())
        print(salida)

        `);
        
      } 
        
      main('This are the second text, I put this text on arguments function');
    </script>
    <div id="origen" >This text is inside of HTML element</div>
 </body>

The output is

['This', 'text', 'is', 'insid', 'of', 'HTML', 'element']
['This', 'are', 'the', 'second', 'text,', 'I', 'put', 'this', 'text', 'on', 'argument', 'function']

But I can't (or I don't know) use function to stemm other kws after load html, for example after load DOM (to get values of my HTML table and run each)

....      
<div id="origen" onclick="temp()">This text is inside of HTML element</div>
   <script>
     myNewkwStemm=main('other word');
     myNewkwStemm2=main('word2');
   </script>
</body>

Solution

You are loading Pyodide multiple times by including the loadPyodide call in the main function, which gives an error for your subsequent main calls. Move loadPyodide outside main should resolve the issue:

<script type="text/javascript">
  let initPyodide = loadPyodide({
    indexURL: "https://cdn.jsdelivr.net/pyodide/dev/full/",
  })
  async function main(kw) {
    let pyodide = await initPyodide
    // ... other code
  }

jsfiddle

Also you probably do not want to rely on pyodide.globals to pass the argument in, it leads to a race condition since you are running everything asynchronously.
