pandas.read_clipboard from cloud-hosted jupyter?

Question

I am running a Data8 instance of JupyterHub running JupyterLab on a server, and pd.read_clipboard() does not seem to work. I see the same problem in google colab.

import pandas as pd
pd.read_clipboard()

errors out like so:

---------------------------------------------------------------------------
PyperclipException                        Traceback (most recent call last)

PyperclipException: 
    Pyperclip could not find a copy/paste mechanism for your system.

Is there a way to get this working?

Answer 1

No. The machine is run in the cloud. Python from there cannot access your local machine to get clipboard content.

I tried Javascript clipboad api, but it didn't work probably because the output is in an iframe which isn't allow access to clipboard either. If it did, this would have worked

from google.colab.output import eval_js
text = eval_js("navigator.clipboard.readText()")
