[BUG] print() doesn't output HTML tags.

print() doesn’t output HTML tags I was experimenting in Pyscript and I tried to print an HTML table, but it didn’t work. It seems to delete the tags and mantain just the plain text.

This is the code that I tried, but it just printed “test” once:

<py-script>
print("<table>")
for i in range (2):
    print("<tr>")
    for j in range (2):
        print("<td>test</td>")
    print("</tr>")
print("</table>")
</py-script>

And this is a screenshot I took of the output:

The “right” or “wrong” to this will always depend on what the use case is. Sometimes you’ll want escaped output and sometimes you won’t.

We just merged #439 which is slightly related to the topic, and here’s a PR that relates to the topic as well but ultimately we need to design a way for users to opt-in/out escaping . At least at the element (<py-script>, <py-repl>) level).

I’m in favor of trying to address this sooner rather than later.

Some workaround is to use some replacement for tags in text - ie. use {{ }} instead of < > and later replace it back with < >

print( "{{b}}Hello World{{/b}}".replace("{{", "<").replace("}}", ">") )
print( "{{h1}}Hello World{{/h1}}".replace("{{", "<").replace("}}", ">") )

or more universal - using function for this

def HTML(text):
     return text.replace("{{", "<").replace("}}", ">")

print( HTML("{{b}}Hello World{{/b}}") )
print( HTML("{{h1}}Hello World{{/h1}}) )

pyscript.write(some_id, HTML("{{h1}}Hello World{{/h1}}) )

document.getElementById(some_id).innerHTML = HTML("{{h1}}Hello World{{/h1}})
