有什么好用的照片去重复软件或者脚本

```python
import os
import hashlib
import time
def main():
start = time.time()
file_del,file_num,md5_all,size_all = 0,0,[],[]
path = input('path:')
if os.path.isdir(path):
for root,dirs,files in os.walk(path):
for name in files:
file = os.path.join(root,name)
file_num += 1
size = os.path.getsize(file)
if size in size_all:
with open(file,'rb') as f:
md5 = hashlib.md5(f.read()).hexdigest()
if md5 in md5_all:
os.remove(file)
file_del += 1
else:
md5_all.append(md5)
else:
size_all.append(size)
else:
print('路径错误!')
end = time.time()
print('共扫描'+str(file_num)+'个文件')
print('共删除'+str(file_del)+'个文件')
print('共耗时'+str(end-start)+'秒')
if __name__ == '__main__':
main()
```
感觉我这样写会误删好多
