一，Json解析

字典转换为JSON：

import json

data =[{"name":"袁震","age":20},{"name":"张三","age":21},{"name":"李四","age":22}]
str =json.dumps(data)
print(str)

 将乱码转换为中文：

import json

data =[{"name":"袁震","age":20},{"name":"张三","age":21},{"name":"李四","age":22}]
str =json.dumps(data,ensure_ascii=False)
print(str)

 将Json字符串转换为列表：

import json

jsonData ='[{"name":"袁震","age":20},{"name":"张三","age":21},{"name":"李四","age":22}]'
listData =json.loads(jsonData)
print("类型：",type(listData))
print(listData)

 二，pyecharts模块 

官方网站：https://pyecharts.org/#/zh-cn/

 画廊网站：https://gallery.pyecharts.org/

pyecharts的安装：

 基础折线图：

from pyecharts.charts import Line

listX =["语文","数学","英语","物理","化学","生物"]
listY =[100,120,130,80,90,70]
line =Line()
line.add_xaxis(listX)
line.add_yaxis("考试成绩",listY)
line.render()

 设置全局配置：

from pyecharts.charts import Line
from pyecharts.options import TitleOpts,LegendOpts,ToolboxOpts,VisualMapOpts
listX =["语文","数学","英语","物理","化学","生物"]
listY =[100,120,130,80,90,70]
line =Line()
line.add_xaxis(listX)
line.add_yaxis("考试成绩",listY)
line.set_global_opts(
    title_opts=TitleOpts(title="袁震的成绩",pos_left="center",pos_bottom="1%"),#控制标题内容和位置
    legend_opts=LegendOpts(type_='plain',
           selected_mode=True,
           is_show=True,
           pos_left=None,
           pos_right=None,
           pos_top=None,
           pos_bottom=None,
           orient='horizontal',
           align='auto',
           padding=5,
           item_gap=10,
           item_width=25,
           item_height=14,
           inactive_color='#ccc',
           textstyle_opts=None,
           legend_icon=None),#图例
    toolbox_opts=ToolboxOpts(is_show=True),#工具箱
    visualmap_opts=VisualMapOpts(is_show=True)#视觉映射
)
line.render()
