使用 PyDrive 将 Pandas DataFrame 作为 Excel 文件直接上传到 Google Drive

Question

我正在尝试将pandas.DataFrame 直接写入 Google 云端硬盘，而不是先在本地写出文件。我找不到解决方案，也不确定它是否可能。我试过下面的代码，但我得到了一个AttributeError。

import pandas as pd
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive

gauth = GoogleAuth()
gauth.LoadCredentialsFile(mycreds)
drive = GoogleDrive(gauth)

df = pd.DataFrame({'a':[1,2],'b':[2,3]})

f = drive.CreateFile({'id': '0B_6_uVX9biFuX0FJWFkt'}) #test.xlsx file
f.SetContentString(df) 
f.Upload()

AttributeError: 'DataFrame' 对象没有属性 'encode'

Answer 1

可以让pandas 直接将 Excel 文件写入如下字符串：

代码：

wb = Workbook()
writer = pd.ExcelWriter('', engine='openpyxl')
writer.book = wb
df.to_excel(writer)
file_as_string = save_virtual_workbook(wb)

完整代码：

这是上面的代码与您的示例相结合。请注意，这部分未经测试。

import pandas as pd
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive

gauth = GoogleAuth()
gauth.LoadCredentialsFile(mycreds)
drive = GoogleDrive(gauth)

df = pd.DataFrame({'a': [1, 2], 'b': [2, 3]})

from openpyxl.workbook import Workbook
from openpyxl.writer.excel import save_virtual_workbook

wb = Workbook()
writer = pd.ExcelWriter('', engine='openpyxl')
writer.book = wb
df.to_excel(writer)

f = drive.CreateFile({'id': '0B_6_uVX9biFuX0FJWFkt'}) #test.xlsx file
f.SetContentString(save_virtual_workbook(wb))
f.Upload()
