Unveiling the Power of Data Manipulation with Pandas
Merging in Pandas
Imagine you have two tables of data with some common columns, and you want to combine them into a single table for easier analysis and manipulation. This is where merging proves to be useful.
Merging can be performed in several ways, depending on how you want to handle the data present in one DataFrame but not in the other. Here’s a brief overview of different types of merging:
- Inner Merge: Combines rows that have matching values in both DataFrames.
- Outer Merge: Includes all rows from both DataFrames, filling in NaNs where there are no matches.
- Left/Right Merge: Includes all rows from the left (or right) DataFrame and the matched rows from the opposite DataFrame.
Each type of merge is suited to different scenarios and requirements, allowing for flexible data manipulation to meet specific analysis needs.
Task
- Create two DataFrames from dictionaries.
- Merge these two DataFrames using the
'key'column as the common column:- Perform the first merge as an inner join.
- Perform the second merge as an outer join.
