226 PointsMy average function doesn't seem to be working. Please, help.
#the main function
def main():
endProgram = 'no'
while endProgram == 'no':
option = 0
print ('Enter 1 to enter in new data and store to file')
print ('Enter 2 to display data from the file')
option = int(input('Enter now ->'))
# declare variables
pints = [0] * 7
totalPints = 0
averagePints = 0
if option == 1:
# function calls
getPints(pints)
getTotal(pints, totalPints)
getAverage(totalPints, averagePints)
writeToFile(averagePints, pints)
else:
readFromFile(averagePints, pints)
endProgram = input('Do you want to end program? (Enter no or yes): ')
while not (endProgram == 'yes' or endProgram == 'no'):
print ('Please enter a yes or no')
endProgram = input('Do you want to end program? (Enter no or yes): ')
#the getPints function
def getPints(pints):
counter = 0
while counter < 7:
pints[counter] = input('Enter pints collected: ')
counter = counter + 1
return pints
#the getTotal function
def getTotal(pints, totalPints):
counter = 0
while counter < 7:
totalPints = int(totalPints) + int(pints[counter])
counter = counter + 1
return totalPints
#the getAverage function
def getAverage(totalPints, averagePints):
averagePints = float(totalPints)/7
return averagePints
#the writeToFile function
def writeToFile(averagePints, pints):
outFile = open('blood.txt', 'a')
outFile.write('Pints Each Hour')
counter = 0
while counter < 7:
counter = counter + 1
outFile.write('Average Pints')
outFile.write(str(averagePints) + '\n\n')
outFile.close()
#the readFromFile function
def readFromFile(averagePints, pints):
inFile = open('blood.txt', 'r')
str1 = inFile.read()
print (str1)
pints = inFile.read()
print (pints)
str2 = inFile.read()
print (str2)
print #adds a blank line
averagePints = inFile.read()
print (averagePints)
inFile.close()
# calls main
main()
I have gone back to the pseudocode and tried a variety of changes in the average statement, such as:
averagePints = int(totalPints)/7
averagePints =int(totalPints/7)
averagePints =int(totalPints)/int(7)
averagePints =float(totalPints/7)
averagePints =float(totalPints)/7
averagePints = totalPints/7
So, my results are looking like this:

Do you want to end program? (Enter no or yes):
So, I don't think the Pints each Hour and Average Pints, are supposed to print on the same line nor without a space between them. Any ideas, on what else I have done wrong, would be greatly appreciated.

226 PointsNever mind, I finally got it! Just in case anyone else needs to know. I don't really have an explanation for why some of the things I tried worked, because my book for my class, doesn't explain what all of these things that we're being told to use mean. Also, because I haven't gotten far enough in the Python classes on here. So, I probably haven't covered that material yet, on here. However, all that being said, here's what finally worked. Oh, I was missing a whole line of code, that was some of the issue. Another issue was that I hadn't wrote my calls correctly, I suppose. Someone else had told me that it didn't matter, that I could write them either way, but I guess in the version of Python that I have, it does matter. I modified some other things, just so it would print the results in a way that was easier to read, in my opinion. So, at long last, here it is:
#the main function
def main():
endProgram = 'no'
while endProgram == 'no':
option = 0
print ('Enter 1 to enter in new data and store to file')
print ('Enter 2 to display data from the file')
option = int(input('Enter now ->'))
# declare variables
pints = [0] * 7
totalPints = 0
averagePints = 0
if option == 1:
# function calls
pints = getPints(pints)
totalPints =getTotal(pints, totalPints)
averagePints = getAverage(totalPints, averagePints)
writeToFile(averagePints, pints)
else:
readFromFile(averagePints, pints)
endProgram = input('Do you want to end program? (Enter no or yes): ')
while not (endProgram == 'yes' or endProgram == 'no'):
print ('Please enter a yes or no')
endProgram = input('Do you want to end program? (Enter no or yes): ')
#the getPints function
def getPints(pints):
counter = 0
while counter < 7:
pints[counter] = input('Enter pints collected: ')
counter = counter + 1
return pints
#the getTotal function
def getTotal(pints, totalPints):
counter = 0
while counter < 7:
totalPints = int(totalPints) + int(pints[counter])
counter = counter + 1
return totalPints
#the getAverage function
def getAverage(totalPints, averagePints):
averagePints = float(totalPints)/7
return averagePints
#the writeToFile function
def writeToFile(averagePints, pints):
outFile = open('blood.txt', 'a')
outFile.write('Pints Each Hour: '+'\n')
counter = 0
while counter < 7:
outFile.write(str(pints[counter])+'\n')
counter = counter + 1
outFile.write('Average Pints: '+'\n')
outFile.write(str(averagePints) + '\n\n')
outFile.close()
#the readFromFile function
def readFromFile(averagePints, pints):
inFile = open('blood.txt', 'r')
str1 = inFile.read()
print (str1)
pints = inFile.read()
print (pints)
print #adds a blank line
averagePints = inFile.read()
print (averagePints)
inFile.close()
# calls main
main()

So, fabulous! And all kinds of excited!!! Thank you to anyone who has helped out with this, from all the way back to a few days ago, even!
