How to split a file into multiple files in Python

How to split a file into multiple files in Python.

Here's a step-by-step tutorial on how to split a file into multiple files in Python:

Step 1: Import the necessary modules

To begin with, we need to import the necessary modules in Python. We will be using the os module to handle file operations.

import os

Step 2: Read the file

Next, we need to read the contents of the file that we want to split. We can use the open() function to open the file in read mode and then use the read() method to read its contents.

def read_file(file_path):
    with open(file_path, 'r') as file:
        content = file.read()
    return content

Step 3: Split the file contents

Now, we will split the file contents into multiple parts based on a specific condition. In this example, let's split the file by lines. We can use the splitlines() method to split the file contents into a list of lines.

def split_file_content(content):
    lines = content.splitlines()
    return lines

Step 4: Create and write to multiple files

Next, we will create and write to multiple files based on the split content. We will iterate over the split content and write each part to a separate file. We can use the enumerate() function to get both the index and value of each line.

def write_to_files(lines, output_dir):
    for index, line in enumerate(lines):
        file_name = f"part_{index}.txt"
        file_path = os.path.join(output_dir, file_name)
        with open(file_path, 'w') as file:
            file.write(line)

Step 5: Putting it all together

Finally, we can put all the steps together and create a function that takes the input file path, output directory path, and splits the file into multiple parts.

def split_file(input_file, output_dir):
    content = read_file(input_file)
    lines = split_file_content(content)
    write_to_files(lines, output_dir)

That's it! Now you can call the split_file() function with the input file path and the output directory path to split the file into multiple parts.

split_file('input.txt', 'output_directory')

Make sure to replace 'input.txt' with the path to your input file, and 'output_directory' with the path to the directory where you want to save the split files.

I hope this tutorial helps you in splitting a file into multiple files using Python!
