Python

a number is entered in the first line of the site, after pressing the button, a python function is used that adds one to the number from the first line, after this the result should be in the second line, but as a result, this is displayed in the second line: function(callback = null) { if( callback != null) { eel._call_return_callbacks[call.call] = {resolve: callback}; } else { return new Promise(function(resolve, reject) { eel._call_return_callbacks[call.call] = {resolve: resolve, reject: reject}; }); } }

python code:

import eel
eel.init('web')
@eel.expose
def my_python_function(a):
    a+=1
    print(a)
eel.start('main.html',size=(500,500))

            let b = await eel.my_python_function(a);
            document.getElementById("ee").value=b;
        }
    </script>

1. Functions are used differently.
https://github.com/ChrisKnott/Eel#return-values 2. For a function to return a value, you need to add , which is logical
let b = await eel.my_python_function(a)();

def my_python_function(a):
    a+=1
    return a
