F-3 Assign Grade
Write a function that accepts a number from 1 to 100 as a result of a test you gave to your students.
If the result is lower than 50 then print Not Pass! Try again next time.
If it is between 50-60 print the grade D.
If it is between 61-80 print the grade C
If it is between 81-90 print the grade B
If it is between 91-98 print the grade A
If it is 99 print 'Almost perfect'
If it is 100 'Take a day-off tomorrow'
Put different values and call the function multiple times to check your result.
