将两个数据框导出为一个excel文件，并在指定位置以两张熊猫纸导出

如何解决将两个数据框导出为一个excel文件，并在指定位置以两张熊猫纸导出

我有两个数据框，如下所示。

df1：

26 2020-02-27        70       NaN            0

df2：

From                to                   plan          score
2020-02-03          2020-02-05           start         20
2020-02-07          2020-02-08           foundation    25
2020-02-10          2020-02-12           learn         10
2020-02-14          2020-02-16           practice      20
2020-02-15          2020-02-21           exam          30
2020-02-20          2020-02-23           test          10

说明：

我已经将两个数据框都加载到了熊猫中，我想将此数据框导出为具有Sheet1 = df1和Sheet2 = df2的1个excel文件。

我在下面尝试过

import pandas as pd
from pandas import ExcelWriter
def save_xls(list_dfs,xls_path):
    with ExcelWriter(xls_path) as writer:
        for n,df in enumerate(list_dfs):
            df.to_excel(writer,'sheet%s' % n)
        writer.save()

save_xls([df1,df2],os.getcwd())

这给了我以下错误。

---------------------------------------------------------------------------

--> 631                     engine = config.get_option(f"io.excel.{ext}.writer")
    632                     if engine == "auto":

     89     if len(keys) > 1:

OptionError: "No such keys(s): 'io.excel..writer'"

During handling of the above exception,another exception occurred:

ValueError                                Traceback (most recent call last)
<ipython-input-16-80bc8a5d0d2f> in <module>

      3         for n,df in enumerate(list_dfs):
      4             df.to_excel(writer,'sheet%s' % n)
      5         writer.save()

解决方法

对我来说，请指定Excel文件，例如：

import os
    
def save_xls(list_dfs,xls_path):
    with pd.ExcelWriter(xls_path) as writer:
        for n,df in enumerate(list_dfs):
            df.to_excel(writer,'sheet%s' % n)
        writer.save()

save_xls([df1,df2],'file.xlsx')
