How will you combine different pandas dataframes ?

The dataframes can be combines using the below approaches:

 

append() method: This is used to stack the dataframes horizontally. Syntax:

df1.append(df2)

concat() method: This is used to stack dataframes vertically. This is best used when the dataframes have the same columns and similar fields. Syntax:

pd.concat([df1, df2])

join() method: This is used for extracting data from various dataframes having one or more common columns.

df1.join(df2)
