Develop applications for Pythonista using web tools.
Paper is a library that allows Pythonista users to develop aplications using HTML, CSS and JavaScript.
Initialize the library:
import paper
# Initialize Paper
app = paper.app('./app')
# Expose the function 'hello' to the JS API
@app.expose
def hello():

<button onclick=“sayHello()”>Hello!</button>
<script>
function sayHello() {
response = paper.py.hello();
alert(response);
}
</script>
</body>
</html>Voilá.
