#Student takes certain number of courses during the academic year. To pass the 
#course, student must receive grade 60 or above.

#Write a function course_pass that has one parameter - number of courses. The 
#function reads final grade for each course, and returns the number of courses 
#student passed.

#Write a program that reads number of courses student takes during the academic 
#year and prints the number of courses student passed and number of courses student 
#failed. Use function course_pass
