用python写一个脚本：将指定目录下所有的srt文件中的，“周期”改成“cycles渲染器”，“电动汽车”改成“EV渲染器”，“自行车”改成“cycles渲染器”，“飞机”改成“平面”，并保存到新的srt文件中

代码：

import os
import re


def replace_text_in_srt(file_path, replacements):
    with open(file_path, 'r', encoding='utf-8') as file:
        content = file.read()

    for old, new in replacements.items():
        content = re.sub(re.escape(old), new, content)

    return content


def save_new_srt(content, new_file_path):
    with open(new_file_path, 'w', encoding='utf-8') as file:
        file.write(content)


def process_srt_files(directory):
    replacements = {
        '周期': 'cycles渲染器',
        '电动汽车': 'EV渲染器',
        '自行车': 'cycles渲染器',
        '飞机': '平面',
        '循环': 'cycles渲染器',
        '价值': '明度',
        '色调': '色相',
        '颜色理论': '色彩理论',

    }

    for filename in os.listdir(directory):
        if filename.endswith('.srt'):
            file_path = os.path.join(directory, filename)
            new_file_path = os.path.join(directory, f'new_{filename}')

            content = replace_text_in_srt(file_path, replacements)
            save_new_srt(content, new_file_path)
            print(f'Processed and saved: {new_file_path}')


# Specify the directory containing the srt files
directory = r'C:\剪映导出'
process_srt_files(directory)
