Dear all,
This is the solution that I came up with to deal with handling the file of
scores.
Thank you all for your feedback!
John
# define calc average function
def calcAve(mylist):
total = 0
count = 0
for i in range (0, len(mylist)):
# count scores for even number items in index
if (i % 2 == 0):
total = total + float(mylist[i])
count = count + 1
return total/count
#Open file called scores and read in data, store in list called lines
infile = open("scores.txt", "r")
lines = infile.readlines()
infile.close()
#print lines
# Create and empty list called names, scores and averages
names = []
averages=[]
#1st for loop to deal with Rows, i.e. names
for line in lines:
tokens = line.split(",")
names.append(tokens[0].strip())
scores = []
#2nd for loop (nested loop) to deal with columns, i.e. scores
for i in range (1, len(tokens)):
scores.append (tokens[i])
#print scores
# define average var, call calcAve function to be used on list called
scores
average = calcAve(scores)
#print average
#append avg scores to var called averages
averages.append(average)
# print averages
for i in range (0, len(names)):
print names[i], "score: ", averages[i]
