Write a program to query a student's grades.
First, define three dictionaries in your code as follows:
python = {'Alex': 83, 'Harry': 77, 'Davy': 93, 'Lisa': 65, 'Sunday': 89}
algorithm = {'Lisa': 91, 'Andrew': 88, 'Kevin': 76}
os = {'Harry': 60, 'Louis': 100, 'Mike': 90, 'Lisa': 58}
Each dictionary represents a course (Python, Algorithm, OS) with the students and their grades in that course.
Your program should accept a student's name and report all of his or her grades in the order: Python, Algorithm, and OS.
If the student isn't taking any of the three courses, report that he or she is not taking any courses.
For example,
$ python3 grades.py
Mary
Mary is not taking any courses.
A student's name.
The result of query.
Note that when reporting the name of the course, you should use 'Python', 'Algorithm', or 'OS', instead of 'python', 'algorithm', or 'os'.
