DataFrame.to_excel多次寫入不同Sheet

主要需要pd.ExcelWriter([文件路徑])方法
參考官方文檔：

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

以下爲實際應用：

"""
df1,df2均爲sql查詢來的數據
excel_filepath爲要生成保存的excel文件地址
"""


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


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