将文本文件拆分为单独的文件，并以文件名保存子字符串；Python

import os

def split_text_file(file_path, chunk_size):
    # 读取文本文件内容
    with open(file_path, 'r') as file:
        text = file.read()

    # 拆分文本为子字符串
    chunks = [text[i:i+chunk_size] for i in range(0, len(text), chunk_size)]

    # 创建保存子字符串的文件夹
    folder_name = os.path.splitext(os.path.basename(file_path))[0]
    os.makedirs(folder_name, exist_ok=True)

    # 保存子字符串为单独的文件
    for i, chunk in enumerate(chunks):
        chunk_file_path = os.path.join(folder_name, f'{i}.txt')
        with open(chunk_file_path, 'w') as chunk_file:
            chunk_file.write(chunk)

    print(f'Successfully split text file into {len(chunks)} chunks.')

# 示例用法
file_path = 'example.txt'  # 文本文件路径
chunk_size = 1000  # 每个子字符串的长度
split_text_file(file_path, chunk_size)
