Question

I am trying to write a program that reads from a list a series of names and numbers like this:

5
Jim
79 84 82
Bob
32 12 47
Kelly
90 86 93
Courtney
80 99 89
Chad
89 78 91

The format for the numbers is:

<Assignment score>   <Quiz Score>   <Exam Score>

And the multipliers for each are:

.3 .1 .6

Currently I have this:

def main():
    inFile = open("input.txt","r")

    numVals = int(inFile.readline())
    for i in range(numVals):
        name = inFile.readline()


    numbers = inFile.readline().split()
    for n in range(len(numbers)):
        numbers[n] = float(int(numbers[n]))

    avg = float(numbers[0]* .3 + numbers[1]* .1 + numbers[2]* .6)
    print(name, "'s Score is",avg,"%.")

    inFile.close()

main()

My output should look like this:

Jim’s score is <avg>.
Bob’s score is <avg>.
Kelly’s score is <avg>.
Courtney’s score is <avg>.
Chad’s score is <avg>.

But instead, I get this:

Kelly
 's Score is <avg> %.

Any ideas on how to get the print to get every name in the file and every line of numbers in the file? Thanks in advance!

Answer 1

You need to strip the trailing newlines from the result of readline.

Maybe like this:

weights = [.3, .1, .6]
with open ('file2.txt') as f:
    count = int (f.readline ().strip () )
    for i in range (count):
        name = f.readline ().strip ()
        score = sum (w * s for w,s in zip (weights, (int (x) for x in f.readline ().strip ().split () ) ) )
        print ('{}\'s Score is {} %.'.format (name, score) )
