In the 8th tutorial in the introduction to programming with python series we introduced for loops.
The video tutorial can be found here:

The exercise for this tutorial is to make the previous exercise, for tutorial 7, more flexible.
For this exercise:

• Initialize an empty grades dictionary variable.
• Prompt the user for the number of students in the class. 
• Convert the number of students to an integer
• Use a for loop to allow the user to enter each student name and grade and add them to the grades dictionary.
• When finished print the grades dictionary back to the user in a more user friendly manner than what we did for the last exercise (See sample program output below)

Here is a sample output of running the program:

Here is the program itself for your reference:
