[Tutor] Hello and some questions.
Hello all.
I recently starting taking Python in my state college. I joined the Python.org
users group and I posted a couple of codes examples that I was having problems
with, and I am wondering if there is anyone in this community that can help me.
I did get some great advice on my previous posts however my code is still not
working. I have two problems that I have to write code for.
The first problem is a program that will take a list of ten grades from a user
and then calculate the average of the ten numbers entered. The user can only
use the numbers 1-10. Example. "The total average of the grades you entered in
was 5" which would be the average using number 1-10 in a sequence, but it needs
to calculate an average no matter if the user puts in 3 "5's" and 7 "10's". The
average must be calculated.
I did get some help in the python forums with this and I have come up the
following, but I am getting a syntax error on the line that calls out "total"
as a variable. Here is the code:
value = [ ]
for i in range(10):
range += 1
print (int(float(raw_input("Please enter a grade, use numbers 1 - 10: ")))
# getting a syntax error on this line
total = sum(value)
average = total/10.0
print "The average sum of all of the grades that you entered is ", ("%.2f" %
average)
raw_input("\nPlease hit enter to quit.")
///The code does not work.
The next problem is supposed to use the while loop. A user is supposed to enter
some grade values. The user will continue to be prompted to enter grade values
until the user has entered in "" as a grade value. Then the program is
supposed to calculate the average of all of the grades entered including the
.
Here is my code, This code is not working either:
target =
value = [ ]
while i in value < or not == target:
i += 1
print grade (int(float(raw_input("Please enter a grade: ")))
total = sum(value)
average = total/target
print "The average grade that you entered is ", ("%.2f" % average)
raw_input("Please hit enter to exit.")
///Can anyone tell me what I am doing wrong on either of these problems? I know
it is a logic error, but I am new to this so please bare with me. Again, thanks
for your help. I am new to this forum so please have patience with me when I am
posting.
Thank you,
Thomas Mundahl

[Tutor] Hello again. and another question.
Hello Trask,
I have been working on the first program. I got the files to read and print out
the grades and averages, but when I write these files to the other txt file,
all that I get is:
10.0
10.0
10.0
10.0
10.0
10.0
10.0
10.0
10.0
10.0
I know it is something simple. I am just not seeing it. Here is my code:
Grades = [ ]
filename = raw_input("Enter the filename with 10 grades to be averaged: ")
my_file_object = open (filename, "r")
for a in range (10):
temp_string = my_file_object.readline()
Grades = Grades + [ float (temp_string)]
my_file_object.close()
for a in range (len(Grades)):
print "Grade", str (a + 1) + ":", Grades [a]
total = 0
for a in range (len(Grades)):
total = total + Grades[a]
average = total/float (len(Grades))
print "The average grade was: ", round(average,2)
print ""
print "Okay, we are assuming that you have created a file named
'grade_file_2.txt' that is empty, yes?"
print ""
fname= raw_input("Please enter 'grade_file_2.txt' to write to new file: ")
grades_file_2 = open("grade_file_2.txt", "w")
for count in range (len(Grades)):
grades_file_2.write(str("%.2f"% (len(Grades))) + "\n")
grades_file_2.close()
print ""
print "Nice Job. your file is done."
///
I am including the files. Let me know if you see anything goofy.
