when the function is defined, and that the same “pre-computed” value is used for each call. This is especially important to understand when a default parameter is a mutable object, such as a list or a dictionary: if the function modifies the object...
Default parameter values are evaluated when the function definition is executed. This means that the expression is evaluated once, when the function is defined, and that the same “pre-computed” value is used for each call. 为了验证这句话,我们修改代码如下 ...
Default parameter values are evaluated when the function definition is executed. This means that the expression is evaluated once, when the function is defined, and that the same "pre-computed" value is used for each call. 大概意思:但解释器执行函数定义时,默认参数值也被计算了,这也意味着默认参数...

not necessarily require calling program input, you can specify default values for these parameters directly when you redefine the function. When the function is called, if no corresponding parameter value is passed, the default value when the function is defined is used instead. In the function ...
