import os
def batch_rename(folder, prefix='file_', start=1):
files = sorted([f for f in os.listdir(folder) if os.path.isfile(os.path.join(folder, f))])
for i, name in enumerate(files, start=start):
ext = os.path.splitext(name)[1]
old = os.path.join(folder, name)
new = os.path.join(folder, f"{prefix}{i:03d}{ext}")
os.rename(old, new)
print(f"已重命名 {len(files)} 个文件")
batch_rename('./照片', prefix='IMG_')
