sandbox = {'test': test}
py_str = 'test("Setting A")\nglobals()["b"] = "Setting B"'

'a' in sandbox # returns False, !What I dont want!
'b' in sandbox # returns True, What I want
'a' in globals() # returns True, !What I dont want!
'b' in globals() # returns False, What I want

我甚至不确定如何询问,但我希望函数的全局范围成为我打算运行它的环境,而不必在eval期间编译函数.这可能吗？

感谢您的任何意见
