Write to a prettified JSON file in Python (with least number of lines of code)

import json

jsonData = ['foo', {'bar': ('baz', None, 1.0, 2)}]
with open('sample.json', 'w') as outfile:
    json.dump(jsonData, outfile, sort_keys= True, indent=4)

Load JSON Files Synchronously with jQuery

In jQuery, the getJSON operator can load any JSON file, however this operation is done asynchronously. Meaning that, in cases where you need to wait until your data file is loaded, using getJSON method is useless. Here is one way you can achieve your goal of loading JSON files synchronously:

function loadJsonFileSynch()
{
        $.ajax({
            url: 'path/to/json/file.json',
            async: false,
            dataType: 'json',
            success: function (response) {
                $.each(response, function(key, val) {
                    // Do processing here
                });
            }
        });
}
