Export Variables Defined in Another File

How to export a variable to another python file

You can try store the users progress data in JSON file.
In python it`s pretty easy, you just need to use json library.

First you should import lib

import json

For example the player`s data looks like this

player_data = {
    'username': 'Nemo',
    'xp': 1000,
    'armor': {
        'name': 'Kaer Morhen armor',
        'weight': 1.57
    }
}

Than you can easely export this data to JSON file

with open("data_file.json", "w") as wf:
    json.dump(player_data, wf)

And import it back

with open("data_file.json", "r") as rf:
    player_data = json.load(rf)

I hope it would be helpful for you :)

Trying to export a bash variable from an .sh file to another file that runs it

Variables are exported from a parent to a child, not vice versa. script_2.sh is called in a different shell whose environment doesn't propagate back to the parent shell.

Source the script (using the .) to call it in the same shell. You then don't even need to export the value.

. ./scripts/script_2.sh

How do I export this variable from class method to another file?

you can have a variable in your class and
assign a value to it inside your services function

class FetchData {

    constructor(device_id, header) {
        this.device_id = device_id;
        this.header= header;
        this.amit = "";
     }

   services() {
       //your sevices code
       this.amit='amit'
     }


} exports.FetchData = FetchData;

then in another file where you are importing FetchData,you can access it with object.varible name.

    var fetchDataObject = new FetchData(device_id, header);
     fetchDataObject.amit //this is your variable amit

when exporting a variable and importing it into another file an undefined error appears, (the paths are correct)

As T.J. Crowder said in his comment,

You're exporting a named export called Movimiento, but trying to import a named export called API. There isn't one, the name is Movimiento. Either: import { Movimiento } from "etc"; ...or if you want to rename it API: import { Movimiento as API } from "etc";

If he posts this as an answer, I will delete this, but I feel as though it needed to be posted as an answer.
