How can I perform operations on a DataFrame in Python?
You can use the pandas library to perform various operations on DataFrames, such as filtering, grouping, and aggregating data.
Can you show me how to filter rows based on a condition?
Sure! You can filter rows using boolean indexing. For example, df[df['column_name'] > value]
will return rows where the specified column's value is greater than a certain value.
What about grouping data? How do I do that?
You can group data using the groupby()
function. For instance, df.groupby('column_name').sum()
will group the DataFrame by the specified column and sum the other columns.
Thanks! Can I also merge two DataFrames?
Yes, you can merge two DataFrames using the merge()
function. For example, pd.merge(df1, df2, on='key_column')
merges them on the specified key column.
