ゝ一世哀愁。 2022-09-04 11:52 235阅读 0赞

# 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][Python] #

# 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 #
