Parsing something with regex

Fri, 12 Jun 2009 20:55:54 -0700

I'm trying to parse some output of the program Nmap with regular expressions.

From this output:

Starting Nmap 4.76 ( http://nmap.org ) at 2009-06-12 22:53 CDT
Interesting ports on jb-Laptop (127.0.0.1):
Not shown: 984 closed ports

MAC Address: 00:09:5B:AA:7E:1A (Netgear)

Nmap done: 2 IP addresses (2 hosts up) scanned in 4.35 seconds

...I'd like to get this:

['21/tcp    open  ftp
22/tcp    open  ssh
25/tcp    open  smtp
110/tcp   open  pop3
139/tcp   open  netbios-ssn

5222/tcp  open  unknown
5900/tcp  open  vnc
10000/tcp open  snet-sensor-mgmt',
'80/tcp open  http']

Right now, I can do as follows:

portdata = re.search("PORT\s+STATE\s+SERVICE.*\d/\S+\s+\S+\s+
\S+", data, re.DOTALL)

This works when I'm getting the ports for just one host, but for more than one it won't match correctly. Any htelp?

Parsing HTML with RegExp: could you help me?

Sat, 30 May 2009 02:37:43 -0700

File 1:

import urllib

hdl = urllib.urlopen("file://localhost/D:/page.htm")
html = hdl.read()
hdl.close()

text_file = open("file.txt", "w")
text_file.write(html)
text_file.close()

File 2:

import re

text_file = open("file.txt", "r")
contents = text_file.read()
text_file.close()

p = re.compile('(?<=starting_html_tag).*(?=ending_html _tag)')
m = p.search(contents)
if m:
print 'Match found: ', m.group()
else:
print 'No match'

The first script opens a particular web page and reads it into a txt file. The second script opens the txt file and looks for contents between tags 'starting_html_tag' and 'ending_html_tag'.

The problem is that the second script doesn't find anything at all. It prints 'No match'. What's the matter?

Why Python

Wed, 06 May 2009 10:11:10 -0700

I've tried in the past to learn C++ and now C#. In both cases I get so far into it and then things just start getting to complicated. Would python be a better place to start? And if so, why? Also, most of the jobs I see in the local adds are for C++, Java, and PHP (.NET). Is there a job market for python programmers?

Problem with python program pls helllllp

Sat, 11 Apr 2009 09:05:42 -0700

Hi..i need help in a program that im trying to write in pyhthon.I have 2 programs made.the first is this:
(The program converts temperatures , so u enter a number for ex. 4 celsius degrees and that is vonverted to 340 kelvin degrees(not correct!) ae a result)

print "Choose what you want to convert.....(type a number from 1 to 6)"
print "1 - Celsius-Kelvin"
print "2 - Celsius-Farenheit"
print "3 - Kelvin-Celsius"
print "4 - Kelvin-Farenheit"
print "5 - Farenheit-Celsius"
print "6 - Farenheit-Kelvin"

deg = input(">: ")

if deg == 1:
celsius1 = input("Type the celsius degrees to convert them to kelvin: ")
kel1 = celsius1+273.15
print "The result is", kel1

if deg == 2:
celsius2 = input("Type the celsius degrees to convert them to farenheit: ")
far1 = celsius2*1.8+32
print "The result is", far1

if deg == 3:
kelvin1 = input("Type the kelvin degrees to convert them to celsius: ")
cel1 = kelvin1-273.15
print "The result is", cel1

if deg == 4:
kelvin2 = input("Type the kelvin degrees to convert them to farenheit: ")
far2 = (kelvin2-273.15)*(9/5)+32
print "The result is", far2

if deg == 5:
farenheit1 = input("Type the farenheit degrees to convert them to celsius: ")
cel2 = (farenheit1-32)/1.8
print "The result is", cel2

if deg == 6:
farenheit2 = input("Type the farenheit degrees to convert them to kelvin: ")
kel2 = (5/9)*(farenheit2-32)+273.15

input("press <enter> to quit")

the second makes a textbox around a typed sentence::

sentence = raw_input("Sentence: ")

screen_width = 80
text_width = len(sentence)
box_width = text_width + 6
left_margin = (screen_width - box_width) // 2

print
print ' ' * left_margin + '+' + '-' * (box_width-2) + '+'
print ' ' * left_margin + '| ' + ' ' * text_width + ' |'
print ' ' * left_margin + '| ' + sentence + ' |'
print ' ' * left_margin + '| ' + ' ' * text_width + ' |'
print ' ' * left_margin + '+' + '-' * (box_width-2) + '+'
print
input('Press <enter> to quit')

the problem starts when i try to make these programs into one program and so the result of the first outputs in a textbox but i have a problem with the strings, tuples and so on.Im a begginer and i found these two programs in a tutorial and i dont know how to do this because i havent learned this yet

Pls help this is urgent here is msn: boris.kaculacki(AT)hotmail.com for contact . THX very much!

help on half adder python

Wed, 01 Apr 2009 03:52:31 -0700

need help on this question:

Draw up the list of possible inputs for a half adder and the
outputs that you expect. Implement a half adder in a few lines of python, so that the
variables o1 and o2 are based on i1 and i2.

i1= True
2 i2= False
3 ............................
o1 =?
5 o2 =?

now i know the function should be something like this :h(i1, i2) =>o1, o2

i have come up with some coding but dont know the formula to put in and how to make all the coding work.

def half_adder(i1, i2):
o1 = # need formula here
o2 = # need formula here
return o1, o2

Programming in Python

Sun, 22 Mar 2009 17:21:59 -0700

Hi, I am trying to teach myself python (which is going very slowly) and I have an assignment to do. Part of the assignment is asking me to read from a text file which contains a list of people's preferences for meals at a restaurant, eg. Bill - steak, fish, chicken; Mary - fish, chicken, steak; Joe - steak, chicken, fish. The assignment wants me to read from the file and then return the preferences as a dictionary. If anyone can help me with writing the code for this, I would be grateful.

Need help with SOAPpy

Wed, 18 Mar 2009 02:01:07 -0700

Hi everyone.

I have a PHP script which works and i need to write the same in Python but SOAPpy generates a slightly different request and

i'm not sure how to fix it so the server likes it.

The request generated by php script looks like this (removed http's from links):

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="schemas.xmlsoap.org/soap/envelope/"
xmlns:ns1="marketing.ews.yahooapis.com/V4"
>
<SOAP-ENV:Header>

<ns1:password>*****</ns1:password>
<ns1:masterAccountID>*****</ns1:masterAccountID>
<ns1:accountID>6674262970</ns1:accountID>
<ns1:license>*****</ns1:license>
</SOAP-ENV:Header>
<SOAP-ENV:Body>
<ns1:getCampaignsByAccountID>
<ns1:accountID>6674262970</ns1:accountID>
<ns1:includeDeleted>false</ns1:includeDeleted>
</ns1:getCampaignsByAccountID>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

When trying to make the same using SOAPPy i get this request:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
SOAP-ENV:encodingStyle="schemas.xmlsoap.org/soap/encodi
ng/"
xmlns:xsi="w3.org/1999/XMLSchema-instance"

<SOAP-ENV:Header>
<username xsi:type="xsd:string">*****</username>
<masterAccountID xsi:type="xsd:string">*****</masterAccountID>

<accountID xsi:type="xsd:integer">6674262970</accountID>
<password xsi:type="xsd:string">*****</password>
</SOAP-ENV:Header>
<SOAP-ENV:Body>
<ns1:getCampaignsByAccountID xmlns:ns1="marketing.ews.yahooapis.com/V4">

<accountID xsi:type="xsd:integer">6674262970</accountID>
</ns1:getCampaignsByAccountID>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

A slightly different request but i guess it should work but i get an error from the server: "Account ID specified in the

header does not match the one specified in the parameter."

But they do match!

The only thing i see is some difference in namespaces, but i have no idea what to do right now. Please help.

FTP File streaming

Wed, 04 Feb 2009 09:59:05 -0700

Hello,

I have been asked to try to program a ftp file stream in python. Here's the complete story:

There's a FTP server with a comma seperated file (csv) on it. A device writes log information in to the csv file whenever something log-worthy occures. This csv file is around 22 MB and keeps on growing. I want to read the latest csv entry that's gotten in to the file. So my question is:

Is it possible to connect to the FTP server, open up a stream to the csv file and retrieve the latest data? I have to able to get a constant stream and always get the latest csv entry.

If this is possible wont there be a conflict when the device is writing to the .csv file and i'm reading from it?

If this isn't possible in python, do you have any idea if it is in another programming language?

Hope i explained everything well enough.

Thanks in advance.

incorporating python user input with a MySQL query

Thu, 25 Dec 2008 17:10:59 -0700

hi,
Im designing a python program that will use a barcode scanner to input barcodes and see if they are in a sql database that i have created.
For the moment, i want a user to manually input a barcode:
barcode = input("Please enter barcode and press Enter button:\n")
then i want to write a query:cursor.execute("select * where #userinput# = 'barcode'"):
where the #userinput# is the barcode that the user has inputted and the 'barocde' is the corresponding barcode in the database. My problem is that i dont know how to tell the program to use the barcode entered by the user in the sql query.
so i need to find the barcode that the user has inputted in a database with a list of barcodes and their corresponding products, using a query(or another method that will do the same thing), and then i want to print the the barcode along with its product.
can someone please help
thanks a million.

Python for loop

Sat, 13 Dec 2008 02:34:04 -0700

Hey all

I have read the tutorial for the for loop in python plenty of time but still can't get it. I know pascal, php, javascript and their for loops are like this(php,javascript) for(i = 0; i < 10 ; i++) which I understand but can someone please help me to understand the for loop of python better.

Thank you

Why does it return 0?

Mon, 10 Nov 2008 15:13:51 -0700

def countErrors(secret, lettersGuessed, errors):

    if lettersGuessed == "":
        errors = errors + 0  
    else:
        subproblem = lettersGuessed[len(lettersGuessed)-1]
        others = lettersGuessed[0:len(lettersGuessed)-1]
        if subproblem in secret:
            errors = errors + 0
        else:
            errors = errors + 1
        print errors, secret, lettersGuessed, others, subproblem
        countErrors(secret, others, errors)
    return errors        
     
        
        

secret = "guinness"
lettersGuessed = "pnitwzg"
errors = 0
x = countErrors(secret, lettersGuessed, errors)
print x

Here's what it outputs:

0 guinness pnitwzg pnitwz g
1 guinness pnitwz pnitw z
2 guinness pnitw pnit w
3 guinness pnit pni t
3 guinness pni pn i
3 guinness pn p n
4 guinness p p
0

I'm pretty new at this, but this just doesn't seem to make any sense. It does exactly what I want it to, except instead of returning 4, it returns 0.

I'm pretty new to Python and i'm havin troubles

Thu, 23 Oct 2008 17:08:53 -0700

Ok I'm new to python since january. i've read a intro book cover-to-cover and have written some code of my own, but i have a nerve-racking problem thats giving my a headache. I can save a module just fine, but when i try to import it into another program it gives me a syntax error and highlights the middle "5" in the "Python 2.5.5" at the top of the page.

Please assist, what's going on and how can i fix it?

Hi i have a question about the python.

Thu, 02 Oct 2008 06:55:30 -0700

You are required to write a Python program which will solve system of linear equations with 3 unknowns
(to be entered by the user).
Your program should display a menu which will allow the user to choose whether he wants to (1)
coefficients (2) check whether the linear system can be solved using iteration (3) calculate and display the
required results using Gauss-Seidel (4) calculate and display the required results using Gauss-Jacobi
Note that in all cases, the outcomes of the iterations should be displayed. Also if the values of the
unknowns are not converging, your program should stop at the 15th iteration.
