I’m trying to use the value of one cell to find the value of a cell in another column. The first cell value (‘source’) dictates which column to lookup.

Reverse a Bokeh Button operation by clicking the button again
I have a vision for a dashboard where you can click on one of several Buttons to perform additive operations, and undo the operation by clicking on the button again.

However, whenever the program runs for the first time,

This is how the conditional statements should be built upon: when stat has a value and both the value of alternative and successor are nothing then only the script should print true.

Questions about In-place memory operations in pandas (1/2)
I was explaining[1] in-place operations vs out-of-place operations to a new user of Pandas. This resulted in us discussing passing objects by reference of by value. Naturally, I wanted to show pandas.DataFrame.values as I thought it shared the memory location of the underlying data of the DataFrame. However, I was surprised with and then sidetracked by the results of the
