Why dont these lines print ?

[Fernando_1]

the names and course and grade dont print, just the totals
Click Here
it reads a file text file
Click Here
the output should look like
Click Here
Im barely learning how to use the control break method and most of the program is broken up in functions.
Im not looking for any fancy functions just the basic that dont deviate from what Ive learned in basic python.
any help is appreciated though :D

Run complete.  Press the Enter key to exit.

I think the 'else' at line 47 is with the wrong if.

[TrustyTony]

looking the long lists of variable names declared global seems strange. If everything is global why you use functions? The function use looks otherwice nice, but reconsider the parameters of them.

[woooee]

What and where do you and to print. I don't see anything in the program that prints name, etc. See Click Here for more info on reading files. Instead, we generally use something like

fp_in = open(file_name, "r")
for record in fp_in:
    # do some stuff
    print record

[woooee]

Hopefully this is not confusing. You can also group all of the records for each name into a list and then process the list containing all of the records for that name.

## Not Tested
## assumes the file is already in name order
## and just reads and prints  each group

def startUp():
    print ("grade report\n").center(60).upper()
    print "name".upper(),"course".rjust(22).upper(),"grade".rjust(32).upper()
    print "-" * 60
    previousName = ""
    list_of_grades=[]
    gradeFile = open("grades.txt","r")
    for rec in gradeFile:
        name, course, grade=readRecord(rec)  
        if name != previousName:
            previousName=name
            if len(list_of_names):
                gradesLoop(list_of_names)
            list_of_names = []  ## remove previous recs
        list_of_names.append([name, course, grade])
    if len(list_of_names):
        gradesLoop(list_of_names)

def readRecord(rec_in):
    currentName = rec_in[0:20].strip()
    course = rec_in[20:50].strip()
    grade = rec_in[50:51].strip()

    return currentName, course, grade

def gradesLoop(list_of names):
    grades_total = 0
    for name, course, grade in list_of_names:
        print name
        print "    ", course, grade
        grades_total += float(grade)
    print "Testing: total of all grades", grades_total

     print "-" *60

We aren't using for loops neither lists. I just need it to print every time it changes category or name. So I put the statement to control if it was on the first categoryTotal loop it only print NAME, COURSE, GRADE and the else statement would print the rest COURSE,NAME

[woooee]

You don't ever print tempStr.

[Fernando_1]

i forgot to add that but once i did the temporary string didnt output correctly, which confused me even further :\

[woooee]

Try just a print statement in the if/else instead of creating tempStr. How you format the print depends on which version of Python you are using. For the "older", version 2.X way Click Here

            name_to_print = ""
            if categoryTotal <= 1:
                name_to_print = currentName

            print name_to_print, course, grade ## formatted correctly
