Assuming you already know how to read in from files, there's a wonderful plotting tool for python called matplotlib that will let you make your pie chart. You'll have to get numpy first, though.

Btw, your link to the text file is broken.

try using link at the top toolbar of your editor. Very helpful to post links.
As buddy said, Matplotlib+wxPython will give you total control. If you do simple plotting, then wxPython have tool for that.

Anyway what do yo want to do with grades? May be python-mysql+wxPython+Matplotlib is all you need

Ok, do us a favour,

I missed the Link to the file.
As far as I can see, you need to look at csv module to help you to do it.
What I propose is:
1. Open file
2. Get contents of one line
3. get that line with delimiter set to space ie ' '
4. Do whatever you want with data
NB: you can print the result to see what it produces before you use the data. Remember to use:

csv.reader(open('grades1.txt'), delimiter=' ')

Actually. your raw data file is tab delimited and easily converted into a list of lists. Once that is done you can simply access your specific data by index and looping through the list.

The only special considerations are that the first line is a header and the last line is an 'end of file' marker.
