请问各位大神要怎么解决这两道问题:
====================

7.        Write a function PrintMovieDetails (movie) to print the details of the movie. It takes in a Movie object as its argument and has no return value. This function improves maintainability.

You must use the get functions created to retrieve the movie detailsfor printing.
       

8.        Write a function SearchBasedOnNameOrCategory(searchString, listOfMovies) to search the matching movies from a provided list of movies with the matching searchString. It takes in a searchString of type String and listOfMovie of type List as its arguments and returns result of type List.

This new function replaces the existing search code



第一个file: Movie.py
============

class Movie:

    def __init__(self,name,category,description,price):
        self.__name=name
        self.__category=category
        self.__description=description        
        self.__price=price

    def getName(self):
        return self.__name

    def setName(self,name):
        self.__name=name

    def getCategory(self):
        return self.__category

    def setCategory(self,category):
        self.__category=category

    def getDescription(self):
        return self.__description

    def setDescription(self,description):
        self.description=description

    def getPrice(self):
        return self.__price

    def setPrice(self,price):
        self.__price=price

    def getPriceWithGST(self):
        result=self.__price*1.07
        return result


第二个file: MovieApp.py
===============
#我把第一个file import去第二个file

from Movie import Movie

def menu1():
    print("\n\nDisplay all movies")
    index = 0
    usrInput = ""
    while usrInput != "M":
        print("\nMovie "+str(index+1)+" of "+str(len(listOfMovies)))
