404,625 | I have scripts to download and extract two shapefiles every 24 hours and create a cleaned DataFrame. I want to append the DataFrame for each one to a specific layer in a gpkg. The only example I can find replaces the contents of the existing layer, but I want to append the new df each day to an existing layer (of two t... | 2021/07/22 | [

gdf_base = gpd.read_file("myfile.gpkg", layer='layer1')
gdf_base = gdf_base.append(df,ignore_index=True)

] | You define a new object `Calc` with a function `add`, but the syntax is incorrect. The correct syntax is:
```
var Calc = {
add: function() {
var num1 = readline.question("num1: ");
var num2 = readline.question("num2: ");
console.log(num1 + num2);
}
};
``` | If you want to make constructor function (I mean from your syntax) you should do it like this:
```
function Calc() {
}
Calc.prototype.add = function() {
var num1 = readline.question("num1: ");
var num2 = readline.question("num2: ");
console.log(num1 + num2);
