来自 警告模块：

 #!/usr/bin/env python -W ignore::DeprecationWarning

如果在Windows上：将 -W忽略：: DeprecationWarning 作为Python的参数。***通过强制转换为 int 。

If you're on Windows: pass -W ignore::DeprecationWarning as an argument to Python. Better though to resolve the issue, by casting to int.

（请注意，在Python 3.2中，默认情况下会弃用警告。）

(Note that in Python 3.2, deprecation warnings are ignored by default.)
