input: Write a function to create a dictionary containing student names and marks as key-value pairs. The function should take a list of tuples where each tuple contains a student's name and their corresponding mark. 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}
  assert construct_student_marks([("Alice", 88), ("Bob", 77)])=={"Alice": 88, "Bob": 77}
  assert construct_student_marks([])=={}
output: def construct_student_marks(student_tuples):
      return {name: mark for name, mark in student_tuples}
