GET() takes 1 positional argument but 2 were given

6.6k views Asked by mathmaniac88 At 24 November 2024 at 19:55

I am new to web.py and I tried making a simple application where I retrieve a HTML file and display it.

Here is my complete code:

import web

render = web.template.render('templates/')

urls = (
    '/(.*)', 'index'
)

class index:
    def GET(self):
        return render.index()

if __name__ == "__main__":
    app = web.application(urls, globals())
    app.run()

When I run this, I get the error message:

<class 'TypeError'> at /

GET() takes 1 positional argument but 2 were given

Whenever I add a random parameter to the GET function, the page is able to function, but otherwise not. It would be great if someone could point out what is going wrong here.

(.*) will be used as second argument, change your code

class index:
    def GET(self, name):
        return render.index(name)

and template index.html

$def with (name)
<html>
<head>
    <title>Hello $name</title>
</head>
<body>
Hello $name
</body>
</html>

now try open http://127.0.0.1:8080/John
