Pandas is a powerful and versatile Python library designed for data manipulation and analysis. It provides two primary data structures: DataFrames and Series, which are used to represent tabular data and one-dimensional arrays, respectively. These structures make it easy to work with large datasets,...
Set logic on the other axes When gluing together multiple DataFrames (or Panels or...), for example, you have a choice of how to handle the other axes (other than the one being concatenated). This can be done in three ways: Take the (sorted) union of them all,join='outer'. This ...
