● DataFrame Creation: Two DataFrames with a common 'ID' column are created.
● Merge: pd.merge() is used to combine the DataFrames on 'ID'.
● Store Result: Merged result is saved in merged_df.
● Output Display: Final merged DataFrame is printed.
Program:
import pandas as pd
df1 = pd.DataFrame({'ID': [1, 2], 'Name': ['Alice', 'Bob']})
df2 = pd.DataFrame({'ID': [1, 2], 'Score': [90, 95]})
