Hey Don!
I posted an eerily similar request to another python group about two weeks
ago! I, too, am very new to programming and the guessing game was my first
shot at writing a script from scratch!
Below is my code (improved with some help from others). I still would like
to make some improvements to it also. But, perhaps there will be some ideas
in it that can help you as well! Looking forward to learning and growing!
All the best!
Malcolm

Subject: [Tutor] Guessing Game Program
Hi folks,
This is a little program I've written to bring together some things I've
been trying to learn (not an attempt, of course, to make an interesting
game).. 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.
I"m sure I've broken some rules along the way, but it does work without any
errors (that I have found).
So, how could I improve it? Is it readable to you, or a mess?
Thanks for your time,
Don

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:
>>> ================================ RESTART
================================
>>>
This program is to calculate your ticket sales to the softball game
Enter the number of class A tickets sold 5
Enter the number of class B tickets sold 5
Enter the number of class C tickets sold 10

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
