What are some useful tips and tricks for using Pandas in Python?

Here are a few tips: 1. Use df.apply() for row-wise operations, 2. Leverage groupby() for aggregations, and 3. Use pd.concat() to combine DataFrames.

Can you explain how to use groupby() with an example?

Sure! You can use groupby() to group data by a specific column. For example, df.groupby('column_name').mean() will give you the mean of each group.

What about handling missing data in Pandas?

You can handle missing data using df.fillna() to fill in missing values or df.dropna() to remove rows with missing values.

Are there any performance tips for working with large DataFrames?

Yes! Use categorical data types for strings, avoid using apply() when possible, and consider using Dask for larger-than-memory datasets.
