Re: [Tutor] While learning Py: To IDE or not to IDE?
In my humble opinion, I think what is important is to get familiar with python for now. The free version of Komodo is what I have been using and its been cool. When you're comfortable with the language and you want to start writing some apps and all of that, you would be matured and independent enough to make a choice as to which editor to go with. Trust me, when you bury your head into writing amazing codes, the choice of editor would come almost naturally. All the best.

Re: [Tutor] python arthematics
What have you tried? What so u intend to achieve?

Re: [Tutor] Making a function run every second.
In my opinion, you probably have to think of how many times it has to run. If
you want to run forever, you can just make an infinite loop.
Here's my try.
import time
def myloop():
while True:
print 'Hi'
time.sleep(1)
This would run forever and print Hi after every 1 second when you run the
program.
What exactly are you trying to achieve.

Re: [Tutor] Variables (with lists??)
Hi Chris,
Straight to the point, this is how to populate a python dictionary.
customer = {}
This statement makes a new dictionary, which is empty though, called customer.
A python dictionary has a pair of key and value linked with semicolon and
seperated from other pairs by a comma.
print “Add a new customer to the database\n”
custNum = raw_input(‘Enter a customer number: ‘)
This expects an input from the user and then sets that to the variable
custName.
Here is a thing to note here, whatever the user enters is treated as a string
because of raw_input. That's another lesson as a whole.
What's in the parenthesis would be shown at the prompt when the program is run.
It tells the user what to do.
customer['firstName'] = raw_input(‘Customer First Name: ‘)
This creates a pair of key value in a dictionary. Initially, the dictionary
customer was empty. This statement now creates a key 'firstname' that has the
value of whatever is entered by the user as the Customer First Name.
customer['lastName'] = raw_input(‘Customer Last Name: ‘)
The same explanation for the above explains this and the rest all through the
customer['zip'] = raw_input(‘Customer Zip Code: ‘)
You can also look at what others would say.
While searching google, search, creating python dictionary.
HTH.

Re: [Tutor] please help - stuck for hours
Where do you intend the variable cash_in to come from? The system doesn't know what cash_in is beyond that you mentioned it and that makes it impossible to multiply it with dollar which is a float type. If cash_in is supposed to be an input from the user, you probably should make it an int type right away before doing the multiplication. Hope this helps. Cheers.

Re: [Tutor] quick data structures question
Hi Fred,
Here is my attempt to solve your task.
import xlrd
def extract(file_name):
choice_file = xlrd.open_workbook(file_name)
choice_sheet = choice_file.sheet_by_index(0)
gene_dict = {}
for row_num in range(1,choice_sheet.nrows):
row_vals = choice_sheet.row_values(row_num)
if int(row_vals[0] * 100) > 20:
gene_dict[row_vals[1]] = row_vals[0] * 100
return gene_dict
Here are few assumptions I made.
1. The your excel file has just two column with headers. Column 1 is High gain
written in % format and column 2 is the gene.
2. that excel returns % format as decimals which is float in python; hence
my conversion to int.
Try this out and let me know how it goes.
Watch the indents carefully. I typed from my blackberry.

Re: [Tutor] Having Troubles with For Loops
To start with, you don't need to do so much for loop.
You have already set the chosen word, word to correct.
Every randomly selected word becomes the value of correct so, you need to only
check for word in correct.
So, after initiating the random selector, you print the number of letters in
the word using the syntax like this:
The player has 5 tries, depending on the approach you intend to adopt, you may
not have to use max_tries.
Say you go for the while loop.
Set tries to 1
correct=word[random.randrange(len(word)-1)]
word = a list of words you want the player to choose from
print 'The word has %d letters' % len(correct)
while tries <= 5:
guess=raw_input('Guess a letter: ')
if guess in correct:
print 'yes'
else:
print 'no'
tries += 1
What you would achieve with the above is that, immediately the player does 5
guesses, the game exits. How do you expect a player to guess a 7 letter word
with just 5 tries.
Second, the player should after 5 tries, if you insist on that, have a chance
to guess the word itself assuming he has he has made two or three guesses,
atleast give him a chance to make a wild guess. You can then tell him if he is
right or wrong and go ahead to tell him the word.
This is just a game logic from my own perspective.
Do the necessary tweak to the cold. If there are other problems, please let's
know.
I hope this helps.

You're going about it wrong. You should look into the len() function.
For example:
print("This word has %d letters" % (len(word)) )
for i in range(5):
letter = input("Guess a letter: ")
if letter.lower() in word.lower():
print("Yes")
else:
print("No")
Your for loops in the end don't do what you think they do.
for letter in XYLOPHONES: # Loops through XYLOPHONES
if letter.lower() not in XYLOPHONES: # Always will return false,
print("No")# because you are looping through the word itself
# etc.
You are also mixing Python 3's print() with Python 2's raw_input(), so
it's hard to tell which you are using. I'm assuming Python 2 because you
didn't report the raw_input() failing. If that's the case, you don't
need the ()'s around the text you are printing.
I also suggest you look into lists and list indexing. You should go
through the Python Tutorial [0] if you haven't before.

[Tutor] Print Help
I want to loop over a list and then print out a one statement that carries all
the items in the list e.g
def checking(responses):
''' Converts strings that look like A2C3D89AA90 into
{'A':'2', 'C':'3', 'D':'89', 'AA':'90'}'''
responses=dict(re.findall(r'([A-Z]{1,2})([0-9]+)', responses.upper()))
if responses else {}
for key in responses.keys():
count = []
if key in ['A'] and int(responses[key]) not in range(1,3):
count += key
elif key in ['B', 'G', 'T', 'U', 'V', 'W', 'X'] and
int(responses[key]) not in range(1, 3): count += key
elif key in ['H', 'J', 'K', 'M', 'N', 'P', 'Q','R','S'] and
int(responses[key]) not in range(1, 6): count += key
elif key in ['D', 'E'] and int(responses[key]) == 4: print
'accepted'
for err in count:
count = ", ".join(count)
print "Invalid Message: You specified out of range values for %s" %
(", ".join(count))
What I am expecting is:
Invalid Message: You specified out of range values for a,s,d,r,t,u
Assuming those were the values that are incorrect.
Ple help.

[Tutor] REGEX EXPLANATION
I have been reading regex in order to work around an assignment.
Could anyone explain to me in plain english what the following regex expression
translate to.
(r'PSC(?P\d{6})(DC|VR)(\d{2})(RC|GA)(\d{3})(!?([A-Z\d]{1,})@?(.*))?',
re.I)
(r'PSC(?P\d{6})VR(?P\d{2})RC(?P\d{3})(?P[ABCDEFGHJKMNPQRSTUVWXYZ\d]{2,})?',
re.I)
(r'PSC(?P\d{6})VR(?P\d{2})(?P(RC|GA))(?P\d{3})!(?P[ABCDEFGHJKMNPQ]{1,})@?(?P.*)',
re.I)
(r'PSC(?P\d{6})DC(?P\d{2})RC(?P\d{3})(?P[ABCDEFGHJKMNPQRSTUVWX\d]{2,})?',
re.I)
(r'PSC(?P\d{6})DC(?P\d{2})(?P(RC|GA))(?P\d{3})!(?P[ABCDEFGHJK]{1,})@?(?P.*)',
re.I)
Like reading it out in plain english. This should further help me understand
how these signs work and then I can get along.
Thanks.

[Tutor] JOB AD PROJECT
Hi, I have done some extensive reading on python. i want to design a classifieds site for jobs. The service is meant to send people who register an sms with available jobs that fit their criteria/cv. But the main idea is that people come and register for quick jobs(like www.freelancer.com) and put up their criteria,age,location,qualificationsand when a company or employer posts a job,the people that fall into the category that was specified get sms and email alerts as to the availability of the job. I am taking this as my first project and would appreciate any help. I am looking in the direction of python, maybe django. Kindly help. Thanks.

Re: [Tutor] Tutor Digest, Vol 81, Issue 35
Hi Joel, To start with, I sincerely appreciate your concern and I am deeply sorry your computer is so infected. Having said that, I think it is unfair to pile all the blames and as a matter of fact, any at all, on this group. That is very unfair to say the least. I don't have an idea of how long you have been on this mailing list but I am quite sure you are not the first to subscribe and you can't be the last. It therefore bothers me that you are the onlt person I have heard say such a terrible thing about this group despite all measures in place to avoid sending malicious elements. I hope you are aware this group doesn't allow attachments except you are suggesting the viruses you are talking about are the letters and numerals in the mails. That then underscores your knowledge as an IT person. Second, you had an option to stick with your PDF and google stuff before coming on this mailing list. If you are all of a sudden attached to your PDF again, it ia matured enough to unsubscribe and be thankful for the things you have learnt in here. While I hope you would have a change of mind and apologise for your very harsh and false accusations, I hope you would also understand that everybody here despite our different backgrounds have gone thus far because we play by the rules and we are interested in not only learning python but teaching too and making everyone smile. Have a great day.

Several third party command line versions exist however, including proprietary ones like Winzip and open source ones. (Google yielded for example this: http://www.pcreview.co.uk/forums/thread-103518.php ) However, you should perhaps have a look at Python's "zipfile" module which should be able to create zip files as well.

Re: [Tutor] Zip Command
Thanks to start with. A byte f python is a book by Swaroop C.H. It is also a book for beginners. Back to the module for zip, do I have to import it into my code for use? It actually works on two lists as you rightly said. I am supposed to create a back up files from 2 directories into another seperate directory on my PC and I want the backup wrapped in a zip folder.

I know about zip files but not zip folders... To create zip files you need to use the zipfile module. > I am working on an example in byte of python but the > zip command is from linux but I use windows. The zip commansd is a standard command and is used for joining two lists. The zipfile module is a standard module that should work across platforms.

How are you running this code? How are you trapping and displaying the exception it gets when run? Can you show us the traceback? Are you looking at the output in a web browser? Which one? And are you doing a view-Source, or whatever your browser offers? A CGI program is intended to run on a web server, and debugging it can be very difficult. Are you sure you want this as a beginner project? If so, then I'd start by saying you should run it locally, till you get rid of all the errors you'll see that way. By inspection, I can see that you should get more than the header, you should also get the element, then it'll crash on the bogus assignment of the uninitialized variable rowNumber. When I run it locally, I get: Content-type: text/html http://www.w3.org/1999/xhtml";> Environmental Variables Traceback (most recent call last): File "M:\cgitest.py", line 27, in rowNumber += 1 NameError: name 'rowNumber' is not defined You don't initialize the global variable rowNumber to anything, but just increment it. You do initialize a local variable in your function with the same name, but nothing is ever done with that, and of course it goes away when the function ends. Same with the backgroundColor local. To fix this problem you'll need to initialize rowNumber before the for statement.
