Example 1: Merge Multiple pandas DataFrames Using Inner Join The following Python programming code illustrates how to perform an inner join to combine three different data sets in Python. For this, we can apply the Python syntax below:
Tables 1 and 2 show the structure of our example DataFrames: Both DataFrames contain different columns and values, but partly overlapping row names.The following examples show how to use these row names to combine our two DataFrames horizontally....
