用pyecharts把下列代码改为嵌套环形饼图from pyecharts.charts import Pie v = ["优秀","良好","中等","及格","不及格"] c = ( Pie() .add( "", [list(z) for z in zip(v,totalseg)], radius=["30%", "75%"], center=["35%", "50%"], rosetype="area", ) .set_global_opts(title_opts=opts.TitleOpts(title="成绩分布图")) .render("pie_rosetype.html") )

用pyecharts将下列代码改为嵌套环形饼图：

from pyecharts.charts import Pie
from pyecharts import options as opts

v = ["优秀", "良好", "中等", "及格", "不及格"]
c = (
    Pie()
    .add(
        series_name="",
        data_pair=[list(z) for z in zip(v, totalseg)],
        radius=["30%", "75%"],
        center=["35%", "50%"],
        rosetype="area",
    )
    .set_global_opts(title_opts=opts.TitleOpts(title="成绩分布图"))
    .set_series_opts(label_opts=opts.LabelOpts(formatter="{b}:{d}%"))
    .render("nested_pie.html")
)

这段代码会生成一个嵌套环形饼图，并将结果保存为"nested_pie.html"文件。请注意，我添加了一个 `.set_series_opts(label_opts=opts.LabelOpts(formatter="{b}:{d}%"))` 来设置标签的显示格式，其中`{b}`表示数据项名称，`{d}%`表示数据项所占的百分比。
