Re: Coding Help
Maybe AutoFlowchart can help you! AutoFlowchart is a excellent source code flowcharting tool to generate flowchart from source code. Its flowchart can expand and shrink. and you can pre-define the the width , height,Horizontal spacing and vertical spacing. Move and zoom is also very easy. It can export the flowchart as a Microsoft Word file or a bitmap file. It can help programmers understand, document and visualize source code. As a new product to replace AgFlowchart, it revised the bugs of AgFlowchart and add many features. It supports C,C++,VC++(Visual C++ .NET),Delphi(Object Pascal). Maybe it can help you! http://www.ezprog.com -- http://mail.python.org/mailman/listinfo/python-list

Coding help...very basic
I need some ideas of how to accomplish this task. I was told that I just need to save the input in a file and make the file searchable, nothing fancy like tying into SQL or Oracle. THis is a basic program and help is greatly appreciated: You've been given an assignment by your supervisor to program a small application to monitor the current status of the cash account in the firm's petty cash fund (the amount of cash kept on hand in the office for incidental purchases). The requirements for the program are to allow users to input the amount of cash deposited, the amount of cash withdrawn and to get a report of the balance at any given time. You will need to also add the date of each deposit and the date of each withdrawal and provide a date with the balance returned upon a given query. The program should be able to provide a printed report and support a command line query. You are to use the object oriented properties of Python to accomplish this task. -- http://mail.python.org/mailman/listinfo/python-list

You insert all chars with the initial response time as the 'key'. You remove the one who is going to respond first and perform his actions. If he is to get another turn, add his next reaction time to the current value and insert him back into the queue. The next character to act will then be at the front of the queue. Repeat. Terry J.

Why don't you try describing what it is you're trying to do in some more

I gather you want to do something like:

... self.initiative = initiative
... self.reaction_time = reaction_time

[...I type 'Steve', '3', '2', etc]
py> characters
[Character('Steve', 3, 2), Character('mx2k', 5, 1)]
But it's not clear to me what it is you want done with the characters.
It looks like you're maybe trying to go through rounds of combat,
sorting characters by initiative...? What exactly is the process you're
attempting to follow?
If you try to describe the problem in words, you'll probably get more
help. (Code is generally good too, but if it's not clear what you're
trying to do with the code, no one will be able to make use of it.)

Since you only want numbers, any alpha char could be used to exit...

print 'The mode, median, and mean? (Please enter Yes or No)'
print 'Please enter Yes or No:'
if raw_input == yes:
First, raw_input() is a function, you need to use the () operator to
*call* (execute) the function.
Then, raw_input() returns a string. A string is something between
quotes. Yes is a symbol (a variable name, function name or like), not a
string. And since this symbol is not defined, you have an exception.
What you want to do is to compare the string returned by the raw_input()
function to the literral string "Yes". What you're doing in fact is
comparing two symbols, one being defined, the other one being undefined...
if raw_input() == "Yes":
f = open("avg.py","r")
Same remark as above about hard-coded file names...
avg.py = f.read()
Notice that the dot is an operator. Here you trying to access the
attribute 'py' of an (actually inexistant) object named 'avg'. What you
want is to bind the data returned by f.read() to a variable.
data = f.read()
print 'The Mean average is:', mean
print 'The Median is:', meadian
print 'The Mode is:', mode
At this time, mean, meadian and mode are undefined symbols. Since you
used the pickle module to persist your data, you should use it to
unserialize'em too. The pickle module is well documented, so you may
want to read the manual.

if raw_input == Yes:
NameError: name 'Yes' is not defined
See above.
I cannot understand how I can define yes so that when they type yes the

Yes = 'yes' ?-)
Also if they type no how do I make the program do
nothing. Or is that just infered.
May I suggest that you :
- subscribe to the 'tutor' mailing-list (it's a ml for absolute beginners)
- do some tutorials (there's one with the doc, and many others freely

- use the interactive python shell to test bits of your code ?

Hi,
have you tried examining the objects you are trying to put together to
see why they might not fit?
For instance, look what happens when you run this, entering 42 at the
prompt:
ri = raw_input('Gimme!')
print type(ri)
print type(int(ri))
print ri == 42
print ri == '42'
name_not_defined_in_this_code
Does looking at the output of that help?
Best,
Brian vdB

Re: NOOB coding help....
Thank you, that does help quit a bit. I am working on the corrections now. To the first poster... don't know what that meant. I thought I made my case understandable. Thank you again. I will work on that. I was attempting to open wade_stoddard... b/c that was my file I was working with, and I was told I had to open it in order to save information to another file so I could recall that information. Thank you again for the help Steven. -- http://mail.python.org/mailman/listinfo/python-list

A simpler approach is to use the second form of the builtin iter
function which takes a callable and a sentinel:
py> def getint():
... return int(raw_input('Number? '))
...
py> numbers = sorted(iter(getint, 0))
Number? 3
Number? 7
Number? 5
Number? 2
Number? 0
py> numbers
[2, 3, 5, 7]
Note that I've renamed 'list' to 'numbers' so as not to hide the builtin
type 'list'.
variableMean = lambda x:sum(x)/len(x)
variableMedian = lambda x: x.sort() or x[len(x)//2]
variableMode = lambda x: max([(x.count(y),y) for y in x])[1]
s = variableMean(list)
y = variableMedian(list)
t = variableMode (list)
See "Inappropriate use of Lambda" in
http://www.python.org/moin/DubiousPython.
Lambdas aside, some alternate possibilities for these are:
def variable_median(x):
# don't modify original list
return sorted(x)[len(x)//2]
def variable_mode(x):
# only iterate through x once (instead of len(x) times)
counts = {}
for item in x:
counts[x] = counts.get(x, 0) + 1
# in Python 2.5 you'll be able to do
# return max(counts, key=counts.__getitem__)
return sorted(counts, key=counts.__getitem__, reverse=True)[0]
Note also that you probably want 'from __future__ import divsion' at the
top of your file or variableMean will sometimes give you an int, not a
float.
x = (s,y,t)
inp = open ("Wade_StoddardSLP3-2.py", "r")
outp = open ("avg.py", "w")
f = ("avg.py")
for x in inp:
outp.write(x)
import pickle
pickle.dump(x, f)
If you want to save s, y and t to a file, you probably want to do
something like:
pickle.dump((s, y, t), file('avg.pickle', 'w'))
I don't know why you've opened Wade_StoddardSLP3-2.py, or why you write
that to avg.py, but pickle.dump takes a file object as the second
parameter, and you're passing it a string object, "avg.py".
f = open("avg.py","r")
avg.py = f.read()
print 'The Mean average is:', mean
print 'The Median is:', meadian
print 'The Mode is:', mode
mean, median, mode = pickle.load(file('avg.pickle'))
print 'The Mean average is:', mean
print 'The Median is:', meadian
print 'The Mode is:', mode

Could you phrase this in the form of a question, like Jeopardy?

NOOB coding help....
Ok, this is what I have so far:
#This program will ask for a user to imput numbers. The numbers will then
be calculated
#to find the statistical mean, mode, and median. Finallly the user will be
asked
#if he would like to print out the answers.
list = [ ]
a = 1
print 'Enter numbers to add to the list. (Enter 0 to quit.)'
while a != 0 :
a = input('Number? ')
list.append(a)
zero = list.index(0)
del list[zero]
list.sort()
variableMean = lambda x:sum(x)/len(x)
variableMedian = lambda x: x.sort() or x[len(x)//2]
variableMode = lambda x: max([(x.count(y),y) for y in x])[1]
s = variableMean(list)
y = variableMedian(list)
t = variableMode (list)
x = (s,y,t)
inp = open ("Wade_StoddardSLP3-2.py", "r")
outp = open ("avg.py", "w")
f = ("avg.py")
for x in inp:
outp.write(x)
import pickle
pickle.dump(x, f)
print 'Thank you! Would you like to see the results after calculating'
print 'The mode, median, and mean? (Please enter Yes or No)'
raw_input('Please enter Yes or No:')
if raw_input == Yes:
f = open("avg.py","r")
avg.py = f.read()
print 'The Mean average is:', mean
print 'The Median is:', meadian
print 'The Mode is:', mode
I am attempting to make it so that I can save the mean, meadian, and mode
and then if the user wants the data to give it to him. Thank you for any
assistance you can provide!
