An example of an AI chatbot conversation about merging DataFrames using Pandas.
How do I merge two DataFrames in Pandas?
You can use the merge() function in Pandas to combine two DataFrames based on a common column.
Can you show me an example of merging on a specific column?
Sure! If you have two DataFrames, df1 and df2, you can merge them like this:
merged_df = pd.merge(df1, df2, on='common_column')
What if the column names are different in both DataFrames?
You can use the left_on and right_on parameters to specify different column names:
merged_df = pd.merge(df1, df2, left_on='df1_column', right_on='df2_column')
Can I perform an outer join instead?
Yes! You can specify the how parameter:
merged_df = pd.merge(df1, df2, on='common_column', how='outer')
