program7.pyThis assignment requires the main function and a custom value-returning function. The value-returning function takes a list of random integers as its only argument and returns a smaller list of only the elements that end with 7. This value-returning function must use a list comprehension to create this smaller list.In the main function, code these steps in this sequence: Set random seed to 42 import randomrandom.seed(42) create an empty list that will the hold random integers. use a loop to add 50 random integers to the list. All integers should be between 200 and 250, inclusive. Duplicates are okay. sort the list in ascending order and then use another loop to display all 50 sorted integers on one line separated by spaces.  print a slice showing list elements indexed 5 through 10, inclusive. print a second slice showing the final 5 elements in the sorted list. execute the custom function with the entire original list as its sole argument. report the number of elements in…

C++Create a text file storage for the list of movies and store your those movies in a linked list when you retrieved them from the text file. They must also be stored in a linked list data structure during processing. Saving back to the text file will be done when the user chooses to Exit the Program.
