Merging DataFrames based on a common column in Pandas
Merge two Pandas DataFrames based on a common column.
Sample Solution:
Python Code:
Output:
ID Name Age 0 2 Sutton 25 1 3 Taneli 30
Explanation:
In the exerciser above -
- First we create two sample DataFrames, "df1" and "df2", with a common column 'ID'.
- The pd.merge function is used to merge the DataFrames based on the 'ID' column.
- The on='ID' parameter specifies the common column on which the merge operation is performed.
- The resulting DataFrame (merged_df) contains columns from both DataFrames, and rows are matched based on the values in the 'ID' column.
