对于参数传递,我总是用传值或者传址来理解,但在《Python基础教程》中建议我们用这样的方法来理解Python中的参数传递:(以Demo1为例说明) 1.#demo1 again:2.defchange1(x):3. x = [1, 2]4. 5.a = [10, 20] 6.print('a is {0}'.format(a))7.change1(a)8.print('a is {0}'.format(a)...

Each component comes with a default search space. The search space for each parameter can be changed or set constant by passing in keyword arguments. In the following example thepenaltyparameter is held constant during the search, and thelossandalphaparameters have their search space modified from...
