Gzip a file in Python

Gzip a file in Python

You can use the gzip module in Python to compress a file using the GZIP compression algorithm. Here's an example of how to gzip a file:

import gzip # Input file name input_file = 'input.txt' # Output compressed file name output_file = 'output.gz' # Open the input file in binary read mode with open(input_file, 'rb') as f_in: # Open the output gzip file in binary write mode with gzip.open(output_file, 'wb') as f_out: # Read data from the input file and write it to the output gzip file f_out.writelines(f_in) print(f'{input_file} has been gzipped to {output_file}.')

In this example:

  1. input_file is the name of the file you want to compress.

  2. output_file is the name of the compressed output file with a .gz extension.

  3. We open the input file in binary read mode using a with statement.

  4. We open the output gzip file in binary write mode using gzip.open() within a with statement. This ensures that the output file is properly closed after compression.

  5. We read the data from the input file and write it to the output gzip file using f_out.writelines(f_in).

After running this code, you'll have a GZIP-compressed file (output.gz) containing the contents of the original file (input.txt). You can adjust the file paths and names to match your specific use case.
