In pandas, you can use theconcat()function to union the DataFrames along with a particular axis (either rows or columns). You can union the Pandas DataFrames using theconcat()function, by either vertical(concatenating along rows) or horizontal(concatenating along columns) concatenation. In this ...
Pandas provides a huge range of methods and functions to manipulate data, including merging DataFrames. Merging DataFrames allows you to both create a new DataFrame without modifying the original data source or alter the original data source. If you are familiar with the SQL or a similar type ...

When joining several data frames, you have an option of how to handle the different axes (other than the one being concatenated). To show you how this can be used, take the union of them all,join='outer'. Consider the intersection withjoin='inner'because it causes no information loss an...
