Assuming you want a list of dicts as the output of the json with each dict be the form in your question:<\/p>\n

The following one liner will put it into the data structure your looking for with each tuple generating it’s own complete structure:<\/p>\n

[{'name':i[0], 'children': [{'name': i[1], 'value': i[2]}]}  for i in tuples]\n<\/code><\/pre>\n
But I suspect you want the outer name to be unique with inner children being built from multiple tuples, such that there is only one such structure generated with 'name' == X<\/code>.<\/p>\n
To do it in a memory efficient manner start by sorting your tuples by X:<\/p>\n
# should work as long as you aren't doing any fancy sorting\nstuples = sorted(tuples) \n\nname = None\ndat = None\nfor t in stuples:\n    if name != t[0]:\n        if dat is not None:\n            writeDat(json.dumps(dat))\n        name = t[0]\n        dat = {'name': t[0], 'children': [{'name': t[1], 'value': t[2]}]}\n    else:\n        dat['children'].append({'name': t1, 'value': t[2]})\n<\/code><\/pre>\n
I assume you have a function to write one of these out such as writeDat()<\/code> that takes the json so you aren’t storing them all in ram.<\/p>\n<\/p><\/div>\n
