Question

你好2018年新年快乐，

我有一些Python / Pandas DataFrame，每个都有不同的名称，我想根据用户的条目选择其中一个，并将其另存为.XLS文件。

我最初的悲惨代码：

import pandas as pd
path = 'C:\\Files\\'


def excel_save(df_name):    
    writer = pd.ExcelWriter(path +'some_name.xls')
    shares.to_excel(writer,'Sheet1')
    writer.save()

#Main
df_name=input ('Enter the name of the DataFrame to be saved as XLS ==>')
excel_save(df_name)

我要传递给excel_save函数的是DataFrame，其名称为df_name，而不是内容为df_name变量的字符串：

我想要保存AAPL DataFrame，而不是空白的东西或者AAPL＆＃39;字符串。

我实际上是在和'exec＆＃39;但还没有找到解决方案：

    #Main
    df_name=input ('Enetr the name of the DataFrame to be saved as XLS ==>')
    excel_save(exec(df_name))

我也尝试过exec（＆＃39; df_name＆＃39;）...到目前为止我没有雪茄

以下也没有用

start=dt.date(2017,12,1)
end=dt.date(2018,1,4)
AAPL = pdr.get_data_yahoo('AAPL', start, end)

AAPL.head()

Out[143]: 'AAPL'

final_path
Out[144]: 'C:\\0_Fabio\\Py Shares Data Manager\\Files\\some_name.xls'

df_name.to_excel(final_path)

Traceback (most recent call last):

df_name.to_excel(final_path)

AttributeError: 'str' object has no attribute 'to_excel'

非常感谢你！法比奥。

据我所知，您希望选定的dataframe文件以excel格式保存到特定路径。如果用户输入是dataframe的名称，则可以直接保存dataframe。

import pandas as pd
path = 'C:\\Files\\'
#main
df_name=input ('Enter the name of the DataFrame to be saved as XLS ==>')
final_path = path + "some_name.xls"
# Note : if type of df_name is just a string, you need to find corresponding data frame and then convert to excel.
df_name.to_excel(final_path)

您可以在多个数据帧的循环中将其保存并保留changine名称。我希望这会有所帮助。

XLS根据用户请求保存DataFrame
