[Tutor] searching data from a list read from a file
Hello J
When you have time I would like some advice on where to go. I have created a
program that reads charge account numbers from a file. The user is to enter
a charge account number from the list presented and the program should then
tell them whether they have entered a valid or invalid number. My problem at
this stage (and yes there a probably more than this one), is when I run the
program it tells me the charge account number is always invalid even when I
put a correct number in. Below is my code because I am thinking that perhaps
it is an indent issue maybe.
This program reads the contents of a file into a list. Asks the user
to enter a charge account number and will determine the validity of the
number entered to return a message of either valid or invalid.

index += 1
# Print the contents of the list
print account_number
#Get an account number to search for
search = raw_input('Enter a charge account number: ')
#Determine whether the product number is in thelist
if search in account_number:
print search, 'charge account number is VALID'
else:

[Tutor] Help with exceptions please
Hello
I have another assignment I am trying to fine tune. The idea is to make sure
exceptions work. I have come up with a problem when testing my code. When I
enter a golf score for a player the program returns the 'error that has
occurred'. I only want it to do this if someone doesn't enter an number.
Could I have some comments on my code for the first program of my assignment
if you have some time please.
Assignment Question: The Springfork Amateur Golf club has a tournament
every weekend.
The club president has asked you to write two programs:
1. A program that will read each player's name and golf score as keyboard
input and then to save these records in a file named golf.txt. (Each record
will have a field name for the player's name and a field for the player's
score.
2. A program that reads the records from the golf.txt and displays them.
def main():
try:
# Get the number of players
golf_scores = int(raw_input('How many players playing this weekend?
'))
# Open a file to hold player names and scores
player_data = open('golf.txt', 'w')
# Get the players name and score and write it to the file
for count in range(1, golf_scores + 1):
# Get the name name and score for player
print 'Enter the name and score for player #' + str(count)
name = raw_input('Name: ')
score = int(raw_input('Score: '))
# Write the data as a record to the file golf.txt
player_data.write(name + '\n')
player_data.write(score + '\n')
# Display a blank line
print
# Close the file
player_data.close()
print 'Players and their score have been written to golf.txt.'
except IOError:
print 'An error occured trying to write information to file.'
except ValueError:
print 'A numberic value must be entered.'
except:
print 'An error occured.'
# Call the main function
main()
Thanks in advance.

[Tutor] Fixed help with exceptions (Lea Parker)
Thank you, Wayne gave me a suggestion which helped me relook at things and
correct the problem I presented. This has added other food for thought for
me such as not allowing the program to accept negative inputs for the score
however, I will have a play to see if I can fix this first and then ask
again if I cannot.
Thanks again.

As I say, just some thoughts,
Thanks for your thoughts, Alan. I had done some testing with cmdline
redirects and forget which is was, I think my debug log was going to stdout
and the apache-style log was going to stderr, or the other way around...
After a handful of guys in the #python IRC channel very nearly convinced me
that all but 3 stdlib libraries are utter worthless crap, and telling me to
download and use third-party frameworks just to fix a simple logging issue,
I overrode log_request() and log message() as such:
class clientThread(BaseHTTPRequestHandler): #[[[
def log_request(code, size):
return
def log_message(self, format, *args):
open(LOGFILE, a).write(%s\n % (format%args))
... and now the only logging going on is my own, and it's logged to my
external file. Overriding log_request means that BaseHTTPServer no longer
outputs its apache-style log, and overriding log_message means my other
logging.info() and logging.debug() messages go out to my file as expected.

[Tutor] return values function
Hello
I am hoping someone can put me on the right track. The code below includes
the assignment question at the beginning.
I seem to have been able to calculate average ok, but what I can't seem to
do is sort it so it will return a grade for each result.
Can you give me some advice to head me in the right direction please. My
code is:
Write a program that asks the user to enter 5 sets tests scores. The
program
should then display the 'letter grade' (A, B, C, D, F) for each test score,
and
the overall average test schore. Write the following functions in the
program:
* Calc_average: This function should take five test scores as parameters,
and
return the average score.
*determine_grade; this function should take a single test score as a
parameter,
and return a letter grade for the test. The letter grade should be on the
following grade scale: 90-100: A, 80-89: B, 70-79: C, 60-69: D, 60: F.
def main():
#Get users first test result
test1 = int(raw_input('Enter the score for test 1: '))
#Get users second test result
test2 = int(raw_input('Enter the score for test 2: '))
#Get users third test result
test3 = int(raw_input('Enter the score for test 3: '))
#Get users forth test result
test4 = int(raw_input('Enter the score for test 4: '))
#Get users fifth test result
test5 = int(raw_input('Enter the score for test 5: '))
#Get the sum of the test results
cal_average = sum(test1, test2, test3, test4, test5)/5
#Display the total of tests
print 'Together your tests average is: ', cal_average
print 'Your grade is: ', grade
# The sum function to total all tests
def sum(test1, test2, test3, test4, test5):
result = test1 + test2 + test3 + test4 + test5
return result
def determine_grade(score):
#Determine the grade for each score
if score 101 and score 89:
score = A
elif score 90 and score 79:
score = B

[Tutor] Help - accumulator not working (Lea)
Hello
I am trying to create this program for a uni assignment. I cannot get it to
add the expenses to the accumulator I have set. Would you mind having a look
and letting me know if I have something in the wrong place or indented
incorrectly. Perhaps I am missing something.
There could be other things wrong but I need to fix this first and then I
can focus on the next thing. I have difficulty trying to fix lots of things
at once so if you could just comment on the problem and I will ask again if
I can't work out the next problem I have. I like to have a go myself first.
J
My code is:
This program is to calculate if the user is over or under budget
for the month
def main():
# Create an accumulator
total_expense = 0.0
# Ask user for the monthly budget
budget = float(raw_input('Enter the amount of your budget for the month:
$'))
# Calculate a series of expenses
expense = float(raw_input('Enter your first expense $'))
# Accumlate expense
total_expense = total_expense + expense
# Continue processing as long as the user
# does not enter 0
while expense != 0:
#Get another expense
expense = float(raw_input('Enter the next expense or 0 to finish

Hello everybody,
I could finally complete succesfully the code I was working with. As I'm
quite new to python, many of the things I have in my code are copied from
different sources, and I do not undertand all of them, well, I have to
deliver this code for a project, and in the best documented way that I
could, I already commented all that I know, and I suppouse wrongly in some
parts.
So the request is, if you can take a look at the code, comment the parts
that are not yet commented, correct the errors, and propouse some
improvement in the parts you think diserves it.
I attach the code in a tgz file, if
the attached can not be seen then this link:

Thanks in advance to all

Hi Michael Scott
Thank you and yes I agree there is room for user error. I am going to add a
validator but I wanted to get the first part right. I appreciate your
comment on the white space too.
Being a beginner I find it easier to write the main thing I want the code to
do and then add extra to make it work efficiently. Perhaps not what a
programmer does but it helps me this way.
Thanks so much.

Hi Lea, how are you today?
Well please keep in mind that nothing is wrong with your code, its doing
exactly what you asked it to do. But I would call your attention to your
while loop, you want to accumulate things, but may I ask exactly what are
you accumulating in your loop?
Also quite by accident I entered 00 as my budget and I got a negative
surplus, lol. Perhaps you should implement something that ensures that a
(stupid) user like myself does not enter a 0- or negative value for the
budget. Just a thought...
To help me attempt to understand the small programs I write, I pretend that
I'm the computer and I literally compute the program as if I was the
interpreter, I follow each line of my code to truly understand it. Perhaps
with these gentle nudges you will solve your problem :)
What is it about you... that intrigues me so?

[Tutor] Help - 2nd validator won't work
Hello
I now need to get the validator to work on my expense input. If the user
puts in a negative I want an error to come up. I have managed it for the
budget input but cannot seem to get it to work for the expense.
Thanks in advance again for your wonderful help.
This program is to calculate if the user is over or under budget
for the month
def main():
# Create an accumulator
total_expense = 0.00
# Ask user for the monthly budget
budget = float(raw_input('Enter the amount of your budget for the month:
'))
# Validation variable for budget
while budget 0:
print 'ERROR: the budget cannot be a negative amount'
budget = float(raw_input('Enter the correct budget for the month:
'))
# Ask user for expense
expense = float(raw_input('Enter your first expense '))
total_expense += expense
# Continue processing as long as the user does not enter 0
while expense != 0:
#Get another expense
expense = float(raw_input('Enter expense or 0 to finish '))
total_expense += expense
# Validation variable for expense
while expense 0:
print 'ERROR: the budget cannot be a negative amount'
expense = float(raw_input('Enter the correct budget for the
month: '))
total_expense += expense
#Calculate surplus
budget_difference = budget - total_expense
#Display results
print 'Your total expenses for the month ', total_expense
if budget_difference=0:
print 'You are under budget by ', budget_difference, 'dollars.'
else:
print 'You are over budget by ', budget_difference, 'dollars.'
# Call the main function.
main()

I've been working my way through a beginner's tutorial, and except for a very basic program I wrote in C++ one time, I think this is the first program I've ever done from scratch. Of course, I've incorporated ideas I've learned from folks on the Internet, my tutorial, and this list.

[Tutor] Error in programming
Hello
Just wondering if you have some time to cast your eyes over another basic
program.
# Prompt user for data
def main():
print 'This program is to calculate your ticket sales to the softball
game'
print #blank line
# Value of each level of seat
a_seat = 15.00
b_seat = 12.00
c_seat = 9.00
# Obtain data
sales_a = int (raw_input('Enter the number of class A tickets sold '))
sales_b = int (raw_input('Enter the number of class B tickets sold '))
sales_c = int (raw_input('Enter the number of class C tickets sold '))
income_generated(a_seat, b_seat, c_seat, sales_a, sales_b, sales_c)
# Obtain data to determine income generated from sales
def income_generated(a_seat, b_seat, c_seat, sales_a, sales_b, sales_c):
total_sales = times the seat value by the number of seats sold for
each seat
and add totals togeter(sale_a * a_seat) + (sale_b * b_seat) + (sale_c
* c_seat)
#Display result to user
print int ('Your total sales for the softball game are: $ ',
total_sales)
# Call the main function
main()
I get the following errors:

My way of thinking is firstly I need to fix line 29 which is main(), I tried
to do this by adding the brackets around text output in line 26. This seemed
to allow me to type main against margin rather than it wanting to indent but
didn't fix the problem. Your suggestions would be appreciated.
Thank
Lea

[Tutor] Python using version 3.1
Hello I am working through a purchased text book Python programming for beginners. Chapter two shows how to create a basic program using triple-quoted strings. I am having problems working out what I have done incorrectly. The game over block writing should stay on the same line but the bottom half of the word over comes up next to the top half of the word over. Hope that makes sense. My code is as follows: # Game Over - Version 2 # Demonstrates the use of quotes in strings print(Program 'Game Over' 2.0) print(Same, message, as before) print(Just, a bit, bigger) print(Here, end= ) print(it is...) print( _ __ ___ / | /| / |/ | | ___| | |/ / | |/ /| / | | |__ | | _/ | / / |__/| | | __| | |_| | / / | | / / | | | |___ \_/ /_/|_| /_/ |_| |_| _ _ _ _ / __ \ | | / / | ___| | _ \ || || | | / / | |__ | |_| | || || | | / / | __| | _ / ||__|| | |/ /| |___ | | \ \ \/ |___/ |_| |_| \_\ ) input(\n\nPress the enter key to exit.) ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
