involves the expression and application of the knowledge accumulated by all mankind throughout history, the work along this path seems to be facing the infinitely daunting problems of mathematics. Therefore, it is crucial to make progress in this direction and to be recognized by society: to be fully aware of the boundaries of any project, the problems that can be solved by any technical means are limited, the limited objectives are clear, and the different stages of implementation of the proje

After reading chapter 18, I found that the first exercise, using *args to read all of the input parameters as a tuple, but in his practice only gave two variables to assign value, when the user is not clear about the definition of this function, it is possible to give too many variables into this function, then the following error occurs:Valueerror:too Many values to unpackSo-called unpacking errors, too many values are given.So in order to stop this situation, I trickery solved the next.
