You have been asked by your professors to write a small Python script to help them analyze assignments for their course. Luckily for you, they only want to analyze a single assignment at a time. They also store all their grading data in CSV files, which you happen to know how to work with!

You will be provided with three CSV files, named in this format:

Assignment#_grades.csv

Each will have data in the following form (data randomly generated using http://www.convertcsv.com/generate-test-data.htm)

Student	Grade
Mitchell Figuson	22
Jordan Warren	82
Matthew Yates	67
Jerome Gill	5

In the final reports, the professor does not want the student names. However, for each class, the professor wants you to calculate the following:

The average grade on the assignment

The highest and lowest grade on the assignment

A histogram of the letter grades, using a typical A to F grading scale as used by most classes. Save it as a dictionary

Your script should be written to accept the csv file being used as input and then print out the stats to the console. The grade histogram should be pickled into a file called grade_hist.pickle. A sample of the first files output is given, while the other two are not provided.

If the file doesnt exist, kindly inform the user the file doesnt exist and exit the program.

Note that the max,min, and average should be calculated efficiently. It is better to use a function than to write your own loop!
