Python script to concatenate all the files in the directory into one file

Python script to concatenate all the files in the directory into one file

You can use Python to concatenate all the files in a directory into one file by iterating through the files in the directory and appending their contents to the output file. Here's a Python script to do that:

import os # Directory containing the files to concatenate directory_path = '/path/to/directory' # Output file where concatenated content will be saved output_file_path = '/path/to/output_file.txt' # Function to concatenate files def concatenate_files(directory_path, output_file_path): try: with open(output_file_path, 'w') as output_file: for filename in os.listdir(directory_path): file_path = os.path.join(directory_path, filename) if os.path.isfile(file_path): with open(file_path, 'r') as input_file: output_file.write(input_file.read()) output_file.write('\n') # Add a newline separator between files print("Files concatenated successfully.") except Exception as e: print(f"An error occurred: {str(e)}") # Call the function to concatenate files concatenate_files(directory_path, output_file_path)

In this script:

  • directory_path should be set to the path of the directory containing the files you want to concatenate.

  • output_file_path should be set to the path where you want to save the concatenated content.

  • The concatenate_files function iterates through each file in the specified directory, reads its content, and appends it to the output file.

  • A newline separator is added between the content of each file in the output file to separate them.

Make sure to replace /path/to/directory and /path/to/output_file.txt with the actual directory path and desired output file path you want to use.

After running the script, the contents of all the files in the directory will be concatenated into the specified output file.
