Python数据分析项目讲解：分析世界五百强企业数据

前言

哪个国家的世界五百强企业数量最多？今天带你用python来处理数据，并实现数据可视化，解决对现有数据产生的疑问。

本次代码是在 Jupyter Notebook 里面编写的

先导入本次代码需要的模块

import pandas as pd
from pyecharts.charts import *
from pyecharts import options as opts
from pyecharts.commons.utils import JsCode
from pyecharts.globals import ThemeType

 

Python从零基础入门到实战系统教程、源码、视频，想要数据集的同学也可以点这里

导入数据

data = pd.read_excel('2021年世界五百强排行榜.xlsx')
data.head(5)

 

统计世界500强企业各个国家之间的占比

pie = Pie(init_opts=opts.InitOpts(theme='light',
                                  width='800px',
                                  height='700px'))

data_x = data1['国家'].tolist()
data_y = data1['排名'].tolist()
                                  
pie.add("",
        [list(z) for z in zip(data_x, data_y)],
        radius=["35%", "55%"]
        )
pie.set_series_opts(label_opts=opts.LabelOpts(position="insideLeft",
                                              font_size=12,
                                              color='rgba(0,0,0,0.5)',

                                              formatter='{b}:{d}%'),
                    itemstyle_opts={'normal': {
                                                'opacity': 1,  # 透明度

                                                'shadowBlur': 5,  # 阴影大小
                                                'shadowOffsetY': 5,  # Y轴方向阴影偏移
                                                'shadowOffsetX': 5,  # x轴方向阴影偏移
                                        }
                                    }
                   )

pie.set_global_opts(legend_opts=opts.LegendOpts(is_show=True, pos_left='right', pos_top='center', orient='vertical'),

                                              visualmap_opts=opts.VisualMapOpts( 
                                                                                min_=0,
                                                                                max_=200,
                                                                                ))    
                                                                                                                         
pie.render_notebook()

 

将国家列设置为索引

bar = Bar(init_opts=opts.InitOpts(theme=ThemeType.PURPLE_PASSION))
bar.add_yaxis("世界500强企业数量", data1['排名'].tolist())
bar.set_global_opts(title_opts=opts.TitleOpts(title="每日电量统计表"),toolbox_opts=opts.ToolboxOpts(),xaxis_opts=opts.AxisOpts(name_rotate=60,axislabel_opts={"rotate":45}))
bar.render_notebook()
# 绘制直方图来显示
# 线性渐变
color_js = """new echarts.graphic.LinearGradient(0, 1, 0, 0,
    [{offset: 0, color: '#008B8B'}, {offset: 1, color: '#FF6347'}], false)"""

bar = Bar(init_opts=opts.InitOpts(theme=ThemeType.DARK))
bar.add_xaxis(data1.index.tolist())
bar.add_yaxis("世界500强企业数量", data1['排名'].tolist(),itemstyle_opts=opts.ItemStyleOpts(color=JsCode(color_js)))
bar.set_global_opts(title_opts=opts.TitleOpts(title="2021年各国世界500强企业统计",subtitle='',pos_left='center',pos_top='3%'), 
                    toolbox_opts=opts.ToolboxOpts(),
                    xaxis_opts=opts.AxisOpts(name_rotate=60,axislabel_opts={"rotate":45}),
