Issue:
`ValueError: The truth value of a DataFrame is ambiguous` when working with Dataframes
Hi, 

I have been periodically getting this error when doing dataframe related operations in the console.   In this particular case, I simply ran "df.to_clipboard()".   I am using Spyder 5.4.3, Python 3.9.16. .

Running the line df.to_clipboard() a second time does not produce the error - fwiw.

```

Discussion:
Hi @mg3146 thank you for the feedback! I was able to reproduce this:

We will check a fix for this in a future release :+1:

Also, not totally sure why but seems like the error comes from IPython? What do you think @ccordoba12 ? Could it be some compatibility issue between pandas and IPython 8.x?

Yeah, I think so too. Please downgrade to IPython 8.7 and try again @dalthviz (that's the last version that I think was working without too many issues).
Is there a way to do that with the standalone installer ?  That’s what I’m using

Sure, you need to close Spyder, open the Anaconda Prompt and run there:

    conda activate fincad_env_v2
    conda install ipython=8.7

And then try again.
Ah, of course IPython uses the active environment.  Sorry I was thinking it would use the dedicated spider environment

Hi there - please note that it is working correctly in the standard IPython console (8.12) but as mentioned above not in the Spyder  IPython console (Spyder 5.4.3 and Pandas 2.0)
![image](https://user-images.githubusercontent.com/2016449/232898321-50a7bdf8-7d0a-4d99-a2c7-cd4eca807a20.png)


@mhabets, the terminal version of IPython runs in a different way than the IPython console in Spyder, so the comparison you posted is actually not correct.

In addition, I can confirm this problem is already fixed in IPython `main` branch and it'll be part of its next version (8.13.0), to be released at the end of month.
Just to add additional symptom - I've been getting this with `head`. If I use the command consecutively, the first instance will always give me the error, but subsequent calls do not give an error:

```

Hi, I was having the same issues, but it seems like there are more functions in the Pandas that have the same issues as above. Even when you are trying to understand the usage of a certain function (where you always put "?" behind the function), it will produce the same error.

For e.g.

```
import numpy as np
import pandas as pd

aa = pd.DataFrame(np.random.rand(10))

aa.value_counts?
Traceback (most recent call last):

I'm using Spyder 5.4.3 and pandas 2.0.1 with Ipython 8.12.0

I had this issue in JupyterLab and in the Spyder ipython console. It was an issue with ipython 8.12.0 and is fixed with ipython 8.13.1 see [#14004](https://github.com/ipython/ipython/pull/14004)
Hence, this can be solved by
- `conda install ipython>=8.13.1` in the development environment.
- Then restart spyder.
