md5.py

import hashlib   
import os
import io
import sys
 
def printUsage():
	print ('''Usage: [python] pymd5sum.py ''')

def geneMd5(filename):
    m = hashlib.md5()
    file = io.FileIO(filename,'r')
    bytes = file.read(1024)
    while(bytes != b''):
        m.update(bytes)
        bytes = file.read(1024) 
    file.close()
    return m.hexdigest()
def main():
    if(len(sys.argv) != 1 and len(sys.argv) != 2):
        printUsage()
    mat = "{:48}\t{:32}"
    if(len(sys.argv)==1):
        path="./"
    if(len(sys.argv)==2):
        path=sys.argv[1]
    for fpathe,dirs,fs in os.walk(path):
        for f in fs:
            full_file = os.path.join(fpathe,f)
            print (mat.format(full_file,geneMd5(full_file)))
main()

运行：
拷贝md5.py 到所需路径下
python md5.py > md5.txt

结果：
