python 多个全路径列表转换为pyecharts tree图所需格式

Question

请问如何将：

item1=['e0', 'e1', 'e7', 'e11']
item2=['e0', 'e1', 'e7', 'e8', 'e9']
item3=['e0', 'e1', 'e2']

转换为pyecharts tree图所需格式：

    data = [
        {"name": "e0",
         "children": [
             {"name": "e1",
              "children": [
                  {"name": "e7",
                   "children": [
                       {"name": "e90"},
                       {"name": "e8",
                        "children": [
                            {"name": "e9"
                             }]}
                   ]},
                  {"name": "e2"},
              ]},
         ],
         }
    ]

 画图

import json

from pyecharts.charts import Page, Tree

def tree_base(data):
    tree = (
        Tree()
            .add("", data)
            .set_global_opts(title_opts=opts.TitleOpts(title="Tree-基本示例"))
    )
    tree.render('./map1.html')
    return tree

tree_base(data)

如果可以的话，能否用以下列表实现：

​

item1=['e0', 'e1', 'e7', 'e11']
item2=['e1', 'e7', 'e8', 'e9']
item3=['e1', 'e2']

Answer 1

item1=['e0', 'e1', 'e7', 'e90']
item2=['e1', 'e7', 'e8', 'e9']
item3=['e1', 'e2']

lis = [item1,item2,item3]
tdict = {}
data = []
for li in lis:
    p = None
    for x in li:
        if x in tdict:
            p = tdict[x]
            continue
        d = {"name": x}
        tdict[x] = d
        if p:
            p.setdefault("children",[]).append(d)
        else:
            data.append(d)
        p = d

import json
print(json.dumps(data,indent=4))
