实用脚本代码：批量处理文件、图片和文本

以下是一些实用的脚本代码：

批量修改文件名

import os

path = '/path/to/files/'
for filename in os.listdir(path):
    # 修改文件名的逻辑
    new_filename = filename.replace('old', 'new')
    os.rename(os.path.join(path, filename), os.path.join(path, new_filename))

批量转换图片格式

from PIL import Image
import os

path = '/path/to/images/'
for filename in os.listdir(path):
    if filename.endswith('.jpg'):
        # 转换图片格式的逻辑
        img = Image.open(os.path.join(path, filename))
        new_filename = filename.replace('.jpg', '.png')
        img.save(os.path.join(path, new_filename))

批量压缩图片大小

from PIL import Image
import os

path = '/path/to/images/'
for filename in os.listdir(path):
    if filename.endswith('.jpg') or filename.endswith('.png'):
        # 压缩图片大小的逻辑
        img = Image.open(os.path.join(path, filename))
        img = img.resize((800, 600))
        img.save(os.path.join(path, filename))

批量转换文本编码格式

import os

path = '/path/to/files/'
for filename in os.listdir(path):
    if filename.endswith('.txt'):
        # 转换文本编码格式的逻辑
        with open(os.path.join(path, filename), 'r', encoding='utf-8') as f:
            content = f.read()
        with open(os.path.join(path, filename), 'w', encoding='gbk') as f:
            f.write(content)

批量替换文本内容

import os

path = '/path/to/files/'
for filename in os.listdir(path):
    if filename.endswith('.txt'):
        # 替换文本内容的逻辑
        with open(os.path.join(path, filename), 'r', encoding='utf-8') as f:
            content = f.read()
        new_content = content.replace('old', 'new')
        with open(os.path.join(path, filename), 'w', encoding='utf-8') as f:
            f.write(new_content)
