How do lambda functions perform in Pandas?

How do lambda functions perform in Pandas compared to regular functions?

Lambda functions in Pandas can be slower than regular functions, especially on large datasets, due to their overhead.

What are some alternatives to using lambda functions in Pandas?

You can use vectorized operations, apply functions, or even NumPy functions for better performance.

Can you give an example of using a lambda function in a Pandas DataFrame?

Sure! You can use a lambda function to create a new column based on existing ones, like this: df['new_col'] = df['col1'].apply(lambda x: x + 1).

Are there any performance benchmarks available for lambda functions in Pandas?

Yes, there are benchmarks that show lambda functions can be significantly slower than vectorized operations, especially with larger datasets.
