理想情况下,我希望在“添加电影”过程中有一个步骤来确认它是一年的整数,一旦被接受,在成功添加电影后继续返回主菜单
(我不想问,也不想问我希望它如何将用户输入数据保存到一个文件中,以便从中提取数据,这样我就不会每次都做一个新条目,哈哈)
这是我得到的。。。再一次,这是我在27小时课程中大概4小时后的努力
我希望你们能理解我想要实现的目标。。。但它只是在“添加电影”功能之后没有正确地“完成”。。。你应该明白我在说什么

def show_movies():
movies[::3]
for c, value in enumerate(movies, 1):
print(c, value)
for movie in movies:
print(f"Name: {movie['name']}")
print(f"Director: {movie['director']}")
print(f"Release Year: {movie['year']}\n")
'''Not done yet
def search_movies():
movies
print("This is where you'd see a list of movies in your database")
'''
menu()
放
在while循环内部,并在循环之前为用户_输入值
就像这样:
此外,还应将电影制作为函数的变量和返回值,或将其设置为全局变量
