How can I handle large files in Python efficiently?

You can use libraries like pandas for data manipulation or dask for parallel processing. What type of files are you working with?

I'm working with CSV files that are several gigabytes in size.

For large CSV files, consider using pandas.read_csv() with the chunksize parameter to read the file in smaller chunks.

Can you give me an example of how to do that?

Sure! Here's a simple example:

import pandas as pd

chunk_size = 10000  # Number of rows per chunk
for chunk in pd.read_csv('large_file.csv', chunksize=chunk_size):
    process(chunk)  # Replace with your processing function
