Data preparation to convert two date field in one
I can suggest you a basic logic, you figure out how to do it. It's not difficult to do it and it'll be a good learning too:

You can read only the subset of columns you need from the input table
as a single dataframe. Make such two dataframes with value as 0 for
the column that you be missing and then append them together.
I have two date columns having corresponding Dollars associated in two other column. I want to plot it in single chart, but for that data preparation in required in python.
Actual table

EndDate
End$
