newname=filename.replace(old_ext,new_ext)
oldpath=path+""+filename
newpath=path+""+newname
print "oldpath:"+oldpath+""
print "newpth:"+newpath+""
try:
os.rename(oldpath, newpath)
except ValueError:
print "Error when rename the file " + oldpath
except NameError:

except OSError:
#print OSError
print newpath + " The file is already exist!"
if __name__ == '__main__':
s_rename("F:code",".ph",".pl")
#print "test"
