DataFrame.to_excel多次写入不同Sheet

主要需要pd.ExcelWriter([文件路径])方法
参考官方文档：

>>> writer = pd.ExcelWriter('output.xlsx')
>>> df1.to_excel(writer,'Sheet1')
>>> df2.to_excel(writer,'Sheet2')
>>> writer.save()

以下为实际应用：

"""
df1,df2均为sql查询来的数据
excel_filepath为要生成保存的excel文件地址
"""


write = pd.ExcelWriter(excel_filepath)
df1 = pd.DataFrame(d_f1)
excel_header = ['日期','年龄']#excel的标题
df1.to_excel(write,sheet_name='Sheet1',header=excel_header,index=False)


df2 = pd.DataFrame(d_f2)
excel_header = ['日期','人数']
df2.to_excel(write,sheet_name='Sheet2',header=excel_header,index=False)
write.save()
