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
