How to Append One Pandas Dataframe onto Another in Python

Knowing how to put two similar lists together is a very important skill for data engineers. In SQL we might just use the Union query to do this, but in Pandas we use the Append method. This will create one big list from two smaller lists of similar structure. Also, we’ll look at how to use the existing indexes, or ignore those to create a new unique index, and how to verify integrity during the append operation. This is an important skill for your toolkit!
