Understanding Python Dictionaries

What is the correct way to create a dictionary in Python with the keys "name", "age", and "courses"?

• `student = {"name": "John", "age": 18, "courses": ["Math", "Science", "History"]}`

• `student = ["name": "John", "age": 18, "courses": ["Math", "Science", "History"]]`

• `student = ("name": "John", "age": 18, "courses": ["Math", "Science", "History"])`

• `student = {"name": "John", "age": 18, "courses": "Math, Science, History"}`

How do you print the entire dictionary named `student` in Python?

• `print student`

• `print(student)`

• `echo(student)`

• `display(student)`

Which of the following is the correct way to access the "name" key from the `student` dictionary?

• `student["name"]`

• `student.name`

• `student->name`

• `student.get("name")`

How can you access the list of courses from the `student` dictionary?

• `student["courses"]`

• `student.courses`

• `student->courses`

• `student.get("courses")`

What is the correct way to add a new key-value pair for "grade" in the `student` dictionary, where "Math" is the course and 90 is the grade?

• `student["grade"] = {"Math": 90}`

• `student["grade"] = "Math": 90`

• `student.grade = {"Math": 90}`

• `student.add("grade", {"Math": 90})`

If you want to print only the student's age from the `student` dictionary, which of the following would you use?

• `print(student["age"])`

• `print(student.age)`

• `print(student->age)`

• `print(student.get("age"))`

Which of the following statements will correctly update the student's age to 19 in the `student` dictionary?

• `student["age"] = 19`

• `student.age = 19`

• `student->age = 19`

• `student.set("age", 19)`

How can you remove the "grade" key from the `student` dictionary?

• `del student["grade"]`

• `student.remove("grade")`

• `student.pop("grade")`

• `student.delete("grade")`

What will be the output of `print(student.get("grade", "No grade available"))` if the "grade" key does not exist in the `student` dictionary?

• `None`

• `No grade available`

• `Error`

• `0`

Which of the following methods can be used to get a list of all keys in the `student` dictionary?

• `student.keys()`

• `student.getKeys()`

• `student.allKeys()`

• `student.listKeys()`
