python标记弃用

1. 标记弃用只需要warnings

2. 需要doc提示，还需要加deprecated装饰器

import warnings
from deprecated.sphinx import deprecated

@deprecated(version='1.0', reason="This function will be removed soon")
def func():
    warnings.warn("被弃用了", DeprecationWarning)
    return 1


if __name__ == '__main__':
    print(func())
