        email = f.cleaned_data['email']
        quota_mb = f.cleaned_data['quota']
        quota = quota_mb * (1 << 20)
        i2 = i2_lic()
        i2.load_code()
        i2.get_info()
        max_quota = i2.get_max_quota_space()
        if max_quota == -1:
            result['error'] = _(u'Failed to set quota: get license quota fail')
            return HttpResponse(json.dumps(result), status=400, content_type=content_type)
        if i2.get_quota_space() + quota > int(max_quota)*1024*1024*1024:
            result['error'] = _(u'Failed to set quota: exceed license allowed(%s GB)') % max_quota
            return HttpResponse(json.dumps(result), status=400, content_type=content_type)

这里圈起来的是调用lic.py中的getxxx(),如果lic.py没有getxxx(),那怎么访问lic.py中类的属性呢？
难道只能这样加getxxx()

回答：

我覺得就去掉! 的確沒有意義!

這些 getter 並沒有實現任何封裝, 以 Python 的觀點而言(甚至以其他語言而言也是, 因為如同 @prolifes 大所講的, 他連屬性都非 private), 這樣做沒什麼道理
