Implement the following function in which students are represented by int IDs and teams are represented
as List [int]. Check the docstring examples very carefully.
def valid_teams (teams: List [List[int]], students: List [int]) -> List [List[int]]:
'''Return a list that contains the teams that have exactly two members who
are in students.
>>> valid_teams ([[1, 2], [3, 4]], [1, 2, 3])

Complete the function below. If a line is long, you may write it in multiple lines at one blank, but please
only write a single statement.
def write_final_grades (assignment_grades: Dict, resubmit_grades: Dict, fname: str) -> None:
"""Write final marks to a final grade file named fname.
assignment_grades maps student numbers to grades for the original assignment
submission. resubmit_grades maps student numbers to grades for the resubmission
of the same assignment. The resubmit penalty of 20% has not been applied within
resubmit_grades. The higher mark, after resubmit penalties are applied, is the
final mark for a student.
Assume that the same student IDs are in both dictionaries.
Assuming "grades.txt" is the original grade file shown (on the previous page) and
"resubmit.txt" is the file above this function header:
>>> original = make_dictionary ("grades.txt")
>>> resubmit = make_dictionary ("resubmit.txt")
>>> write_final_grades (original, resubmit, "final.txt")
Then final.txt should look as follows:

Create the function initialize_list(n, value) that takes as a parameter an integer n and a value. It creates 4 lists with length 10 where the initializers are taken from the list [ ‘*’, 10, 12.0 , -1], i.e. one list is all *s, another all 10’s etc. (Expected output is shown in the image attached)

This chapter defined and identified various operations on a circular linked list. 1. Write the definitions of the class circularlinkedList and its member functions. (You may assume that the elements of the circular linked list are in ascending order.) 2. Write a program to test various operations of the class defined in the step above. Your program should accept a sorted list as input and output the following: • The length of the list. • The list after deleting a number. • A message indicating if a number is contained in the list.
