input: Write a function to create a dictionary containing student names and marks as key-value pairs. The input is a list of tuples where each tuple contains a student's name and their corresponding marks. The function should return the constructed dictionary.
  assert construct_student_marks([("John", 90), ("Levi", 85), ("Jill", 95), ("Sara", 75)]) == { 
      "John" : 90, 
      "Levi" : 85, 
      "Jill" : 95, 
      "Sara" : 75
  }
output: def construct_student_marks(student_list):
      return {name: marks for name, marks in student_list}
