python實例26[計算MD5]
代碼如下：
from hashlib import md5
def calMD5(str):
m = md5()
m.update(str)
return m.hexdigest()
def calMD5ForFile(file):
m = md5()
a_file = open(file, 'rb')
m.update(a_file.read())
a_file.close()
return m.hexdigest()
def calMD5ForFolder(dir,MD5File):
import os
outfile = open(MD5File,'w')
for root, subdirs, files in os.walk(dir):
for file in files:
filefullpath = os.path.join(root,file)
print filefullpath
filerelpath = os.path.relpath(filefullpath,dir)
md5 = calMD5ForFile(filefullpath)
outfile.write(filerelpath + ' ' + md5 + '\n')
outfile.close()
print calMD5('This is one test string')
print calMD5ForFile('c:\\test\\mytest.txt')
calMD5ForFolder('c:\\test','c:\\mdfile.md5')
def calMD5(str):
m = md5()
m.update(str)
return m.hexdigest()
def calMD5ForFile(file):
m = md5()
a_file = open(file, 'rb')
m.update(a_file.read())
a_file.close()
return m.hexdigest()
def calMD5ForFolder(dir,MD5File):
import os
outfile = open(MD5File,'w')
for root, subdirs, files in os.walk(dir):
for file in files:
filefullpath = os.path.join(root,file)
print filefullpath
filerelpath = os.path.relpath(filefullpath,dir)
md5 = calMD5ForFile(filefullpath)
outfile.write(filerelpath + ' ' + md5 + '\n')
outfile.close()
print calMD5('This is one test string')
print calMD5ForFile('c:\\test\\mytest.txt')
calMD5ForFolder('c:\\test','c:\\mdfile.md5')
