python json treeview

Python中的json treeview通常用于将json数据以树形结构展示出来。可以通过Python内置的json库来解析json数据，并使用Python的tkinter库创建GUI界面进行展示。

以下是一个简单的示例代码，可以将json数据以树形结构展示出来：

import tkinter as tk
import json

class JsonTreeView:
    def __init__(self, master, data):
        self.master = master
        self.tree = tk.ttk.Treeview(master)
        self.tree.pack(fill=tk.BOTH, expand=1)

        self.add_tree_item("", data)

    def add_tree_item(self, parent, item):
        if isinstance(item, dict):
            for key in item:
                node = self.tree.insert(parent, "end", text=key)
                self.add_tree_item(node, item[key])
        elif isinstance(item, list):
            for i in range(len(item)):
                node = self.tree.insert(parent, "end", text=str(i))
                self.add_tree_item(node, item[i])
        else:
            self.tree.insert(parent, "end", text=item)

def main():
    data = '''
    {
        "name": "John",
        "age": 30,
        "cars": [
            { "name":"Ford", "models":[ "Fiesta", "Focus", "Mustang" ] },
            { "name":"BMW", "models":[ "320", "X3", "X5" ] },
            { "name":"Fiat", "models":[ "500", "Panda" ] }
        ]
    }
    '''
    root = tk.Tk()
    root.title("JSON Tree View")
    data_dict = json.loads(data)
    JsonTreeView(root, data_dict)
    root.mainloop()

if __name__ == '__main__':
    main()

运行这个代码，可以得到一个简单的GUI界面，展示了一个json数据的树形结构。
