How to export a variable to another python file-CodePudding

Hi all I am creating a game that allows the user to export their progress to another file which can be loaded back up again once they come back. I am wondering if there is a way to export multiple variables to a different file, which will then change the file in the computer's memory. I have a way to import the variables, I just need some help with the exporting part, thank you for your help, Darren.

CodePudding user response：

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 :)
