outside the function are global variables, inside the function are local variables, Python built-in variables. Follow the variable lookup order of the local > global> built-in.For ease of differentiation, global variables are all capitalized. If you need to use global variables within a function, you need to precede the variables with global.1 defTop_movies (num=5, *args, * *Kwargs):2 Print(num)3 Print(args)4 Print(Kwargs)5 6Rank = (0, 1, 2, 3, 4, 5)7Keywords = {'1':'The Shawshank R

So there's a new role for GXQSD, and the right approach should be to store the new role entity information.Next, a simple diagram is used to describe the relationship between database tables.We define
