Use theconcat()Function to Concatenate Two DataFrames in Pandas Python Theconcat()is a function in Pandas that appends columns or rows from one dataframe to another. It combines data frames as well as series. In the following code, we have created two data frames and combined them using the...
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 is the default option as it ...
