根据md5去重文件

import os
import hashlib

def get_md5(file):
    file = open(file,'rb')
    md5 = hashlib.md5(file.read())
    file.close()
    md5_values = md5.hexdigest()
    return md5_values

file_path = "G:lizhi_music"
os.chdir(file_path)
file_list = os.listdir(file_path)
md5_list =[]
for file in file_list:
    md5 = get_md5(file)
    if md5 not in md5_list:
        md5_list.append(md5)
    else:
        os.remove(file)
        print("文件：%s已删除"%file)
