This will give you the complete documentation you are looking for, just within the code cell, unfortunately not a pop out window like Jupyter Notebook. Example of documentation in vscode-jupyter. This contextual help issue is being tracked here on vscode-jupyter GitHub.
As this question is already fully explained and discussed in existing answers, I will just provide a neat pandas approach to the context manager using pandas.option_context (links to documentation and example) - there is absolutely isn't any need to create a custom class with all the dunder methods and other bells and whistles.
Obligatory disclaimer from the documentation. Iterating through pandas objects is generally slow. In many cases, iterating manually over the rows is not needed and can be avoided with one of the following approaches: Look for a vectorized solution: many operations can be performed using built-in methods or NumPy functions, (boolean) indexing, …

count() returns the total number of non-null values in the series. value_counts() returns a series of the number of times each unique non-null value appears, sorted from most to least frequent.
There is no built-in method in pandas to reverse the order of a DataFrame, hence why you wont find any specific information on that in the documentation. In order to reverse a DataFrame you will have to use either reversed() (which is a function that is part of the standard library of python ) or use slice notation as suggested in the thread ...
I am pretty sure that ~ in Pandas is boolean not. I found a couple of StackOverflow questions / answers, but no pointer to official documentation. Sanity Check #!/usr/bin/env python # -*- coding:...
Referring to the section Define original properties (of the official Pandas documentation) and if subclassing from pandas.DataFrame is an option, note that: To let original data structures have additional properties, you should let pandas know what properties are added. Thus, something you can do - where the name MetaedDataFrame is arbitrarily ...
Pandas background gradient coloring takes into account either each row or each column separately while matplotlib's pcolor or pcolormesh coloring takes into account the whole matrix. Take for instance the following code pd.DataFrame([[1, 1], [0, 3]]).style.background_gradient(cmap='summer') results in a table with two ones, each of them with a ...
It is pretty simple to add a row into a pandas DataFrame: Create a regular Python dictionary with the same columns names as your Dataframe; Use pandas.append() method and pass in the name of your dictionary, where .append() is a method on DataFrame instances; Add ignore_index=True right after your dictionary name.
