def fil_changefileext(filename,extname=''):

FIL ChangeFileExt 改動文件擴展名

# filename    輸入的文件途径名
# extname=''  要更改分擴展名，如 .txt
import os
try:
    if extname[0]<>'.':
        extname='.'+extname
except:
    extname=''
if os.path.splitext(filename)[1]=='':
    uouttxt=filename+'.'+extname
elif os.path.splitext(filename)[1]=='.':
    uouttxt=filename+extname   
else:
    uouttxt=filename[:0-len(os.path.splitext(filename)[1])]+extname
return uouttxt

def fil_str2file(fstr,filename):

FIL STR2File 把字符串保管到文件

try:
    outfile=open(filename,'w')
    outfile.writelines(fstr)
    outfile.close()
    return True   
except:
    return False

係統主程序開端

pjy=0

ffm=os.path.basename(filepathname)
#開端處置
print 'Program Runing "'+filepathname+'" ...'
import hashlib

usha1str = hashlib.sha1()
xfilepathname=unicode(filepathname,'utf8')
#需求運用二進製格式讀取文件内容
ufile = file(xfilepathname,'rb')

datas = ufile.read(1024512)
if not datas: break
umd5str.update( datas )

ppos=int(math.floor(fpos / fmaxs 50))
pposbfh=int(math.floor(fpos / fmaxs 100))
#打印進度條
if pjy<>ppos: print '['+''ppos +'='(pmax-ppos)+'] '+str(pposbfh) +'%'
#打印進度問題未處理，不晓得print函數怎樣退回到行首掩蓋輸出，不換行我倒是晓得，加個“,”
pjy=ppos
uoutstrmd5=str(umd5str.hexdigest())
uoutstrsha1=str(usha1str.hexdigest())
ufile.close()
print ''
fil_str2file(uoutstrmd5+' '+ffm+'\n',fmd5)

print 'Task is completed !' + r' [ XingHe Studio File to MD5 and SHA1 ]'
except:
print 'Error !' + r' [ XingHe Studio File to MD5 and SHA1 ]'
else:
print 'File "'+filepathname+'" not exist!'+ r' [ XingHe Studio File to MD5 and SHA1 ]'
else:
