How to unzip gz file using Python

How to unzip gz file using Python

You can use the gzip module in Python to unzip .gz files. Here's how you can do it:

import gzip # Path to the gzipped file gzipped_file_path = 'path/to/your/file.gz' # Output file path (without .gz extension) output_file_path = 'path/to/output/file' # Open the gzipped file and the output file with gzip.open(gzipped_file_path, 'rb') as gzipped_file, open(output_file_path, 'wb') as output_file: output_file.write(gzipped_file.read())

In this example, replace 'path/to/your/file.gz' with the actual path to your gzipped file and 'path/to/output/file' with the desired path for the output file (without the .gz extension). The code opens the gzipped file in binary read mode ('rb') using the gzip.open() function and the output file in binary write mode ('wb') using the built-in open() function.

When reading from the gzipped file, the code uses gzipped_file.read() to read the compressed data and then writes it to the output file using output_file.write(). This effectively unzips the contents of the .gz file into the output file.

After running this code, you'll have the unzipped content in the specified output file.

Examples

    • Description: This code demonstrates how to unzip a .gz file using the built-in gzip module in Python.
    • Code:
      import gzip # Path to the gz file gz_file = 'example.gz' # Path to the output file output_file = 'unzipped_file.txt' # Unzipping the gz file with gzip.open(gz_file, 'rb') as f_in: with open(output_file, 'wb') as f_out: f_out.write(f_in.read())

  2. Python code to unzip a .gz file using shutil module

    • Description: This code uses the shutil module to unzip a .gz file, providing a simpler interface for file operations.
    • Code:
      import shutil # Path to the gz file gz_file = 'example.gz' # Path to the output file output_file = 'unzipped_file.txt' # Unzipping the gz file using shutil module with open(output_file, 'wb') as f_out: with gzip.open(gz_file, 'rb') as f_in: shutil.copyfileobj(f_in, f_out)

  3. Python code to unzip a .gz file using subprocess module

    • Description: This code utilizes the subprocess module to execute system commands for unzipping a .gz file.
    • Code:
      import subprocess # Path to the gz file gz_file = 'example.gz' # Path to the output file output_file = 'unzipped_file.txt' # Unzipping the gz file using subprocess module subprocess.run(['gzip', '-d', '-c', gz_file], stdout=open(output_file, 'wb'), check=True)

  4. Python code to unzip a .gz file using tarfile module

    • Description: This code demonstrates how to unzip a .gz file using the tarfile module, which provides support for various archive formats.
    • Code:
      import tarfile # Path to the gz file gz_file = 'example.gz' # Path to the output file output_file = 'unzipped_file.txt' # Unzipping the gz file using tarfile module with tarfile.open(gz_file, 'r:gz') as tar_ref: tar_ref.extractall(output_file)

  5. Python code to unzip a .gz file using gzip module with streaming

    • Description: This code unzips a .gz file using the gzip module with streaming, avoiding loading the entire file into memory at once.
    • Code:
      import gzip import shutil # Path to the gz file gz_file = 'example.gz' # Path to the output file output_file = 'unzipped_file.txt' # Unzipping the gz file with streaming with gzip.open(gz_file, 'rb') as f_in: with open(output_file, 'wb') as f_out: shutil.copyfileobj(f_in, f_out)

  6. Python code to unzip a .gz file using gzip module with text mode

    • Description: This code unzips a .gz file using the gzip module with text mode, allowing you to specify the encoding of the output file.
    • Code:
      import gzip # Path to the gz file gz_file = 'example.gz' # Path to the output file output_file = 'unzipped_file.txt' # Unzipping the gz file with text mode with gzip.open(gz_file, 'rt') as f_in: with open(output_file, 'w') as f_out: for line in f_in: f_out.write(line)

  7. Python code to unzip a .gz file using gzip module with binary mode

    • Description: This code unzips a .gz file using the gzip module with binary mode, ensuring compatibility with non-text files.
    • Code:
      import gzip # Path to the gz file gz_file = 'example.gz' # Path to the output file output_file = 'unzipped_file' # Unzipping the gz file with binary mode with gzip.open(gz_file, 'rb') as f_in: with open(output_file, 'wb') as f_out: f_out.write(f_in.read())

  8. Python code to unzip a .gz file using gzip module with streaming and binary mode

    • Description: This code combines streaming and binary mode to unzip a .gz file efficiently without loading it entirely into memory.
    • Code:
      import gzip import shutil # Path to the gz file gz_file = 'example.gz' # Path to the output file output_file = 'unzipped_file' # Unzipping the gz file with streaming and binary mode with gzip.open(gz_file, 'rb') as f_in: with open(output_file, 'wb') as f_out: shutil.copyfileobj(f_in, f_out)

  9. Python code to unzip a .gz file using gzip module with chunked reading

    • Description: This code unzips a .gz file using the gzip module with chunked reading, enabling efficient processing of large files.
    • Code:
      import gzip # Path to the gz file gz_file = 'example.gz' # Path to the output file output_file = 'unzipped_file.txt' # Unzipping the gz file with chunked reading with gzip.open(gz_file, 'rb') as f_in: with open(output_file, 'wb') as f_out: chunk_size = 1024 while True: chunk = f_in.read(chunk_size) if not chunk: break f_out.write(chunk)

  10. Python code to unzip a .gz file using gzip module with decompressobj

    • Description: This code utilizes the decompressobj from the gzip module for low-level gzip decompression, providing more control over the unzipping process.
    • Code:
      import gzip # Path to the gz file gz_file = 'example.gz' # Path to the output file output_file = 'unzipped_file.txt' # Unzipping the gz file with decompressobj with gzip.open(gz_file, 'rb') as f_in: decompressor = gzip.decompressobj() with open(output_file, 'wb') as f_out: while True: chunk = f_in.read(1024) if not chunk: break decompressed_chunk = decompressor.decompress(chunk) f_out.write(decompressed_chunk)
