'''process a file of students''' 

def main(): 
    f = open( "Ex9_2010_input.txt", "r") 
    line = f.readline() 
    while len(line) != 0: 
        print line 
        line = f.readline() 

main()

In this case, the file contains comma separated values, each line representing student names and assessment marks in this format:
FirstName, LastName, Asg1Mark, Asg2Mark, ExamMark
Here are a couple of example lines from the file:
Fred, Nurke, 16, 17, 22
Jack, Sprat, 12, 13, 19


I need to modify the code i have written above to extract the different fields from each line of input and then calculate the final grade. and then i need Print out each student’s names and final grade.


Any insight in how i can approch this would be great

Thanks

Hint:

line='Fred, Nurke, 16, 17, 22'
line=line.split(',')
numbers=[float(mark) for mark in line[2:]]
average = sum(numbers)/len(numbers)
print "%s, %s: %.1f" % (line[0],line[1], average)

Your code seems to work well, except your grade assignments are a little strange to me.

Here would be a slightly different approach to some of your code:

""" assume these are the contents of file student.txt
Fred, Nurke, 16, 17, 22
Jack, Sprat, 12, 13, 19
"""

# create a list of each student's
# [firstName, lastName, asg1Mark, asg2Mark, examMark] data list
studentList = []
for line in open("student.txt"):
    tempList = []
    for item in line.split(","):
        # strip leading spaces and trailing newline char
        item = item.strip()
        #print item  # test
        tempList.append(item)
        #print temp_list  # test
    studentList.append(tempList)

print studentList  # test

for student in studentList:
    firstName, lastName, asg1Mark, asg2Mark, examMark = student
    totalMarks = int(asg1Mark) + int(asg2Mark) + int(examMark)
    # test
    print "%s %s total mark = %d" % (firstName, lastName, totalMarks)

Your did little mistake with tags, you can use the button (code) to add code tags for selection.
