Have a look in this page http://wiki.python.org/moin/IntegratedDevelopmentEnvironments

Thanks friends.but which one has this ability?

Hello again friends.
I need an article o book or any wrote that discussed about storage engines structure.
for example explain that what made MyISAM faster than other engines in Inserting data or any such thing that argue the graphs that came in upper post link.

http://www.mysqlperformanceblog.com/2007/01/08/innodb-vs-myisam-vs-falcon-benchmarks-part-1/

Thanks.

Friends, no one use an interface with this ability?
So if you want to trace your codes step by step, How do u do it?

Lets discuss stronger.
Lets List all _or at least more important_ interfaces of python that use in different operation systems.
for example a list of python interfaces that are used in linux, windows, mac or etc.

at first a want do it on yahoo.

I did but realy culden't find any suitable source.
what is your exact keyword to search?

Sorry dear.
It maybe to explain more or introduce me a direct source?

I realy know nothing about this works.
Introduce me module, book or anything which can help me.

Thanks alot.

I used pyScripter.and when I write my code can trace it step by step with F7.
I need an interface like it in linux _ubuntu_.

Hello dears.
I am using python 2.6 in Ubuntu 10.10.

Realy I have I gsm modem _witch are used in mobiles for sending and receiving sms_
I have to send and receive sms with that in my program.but I don't know how I can do it
I find some modula such as pysms and pygsm to do it but they have no suitable flexibility
and I don't know witch one is better or maybe I have to do it in another way at all.
I confused that what I have to do and how I have to start it.
please guide me.
thanks.

Hi dears.
I want make relation with gsm modem.
my first goal and main one is sending and receiving sms.
_then I want go front.for example for mms sending and ..._
I want to do it on a linux server.
please introduce me a suitable modula with it's tutorial or documentation.
thanks if guide me.

sorry I can not write eng well.
we can play command line's commands in python.
for example in cmd you can play "cls" to clear command line.
and in python we do it like below code:

import os
os.system("cls")

it will play well.but some of commands are that you have to return again to command line and play a new command.

for example:

c:\>

manualy at first you have to type nslookup.then you have to wait.you will see second line that apear like below:

nslookup>

after you have to enter another command.for example:

nslookup>server 127.0.0.1

now I can not play such instructions.I have to return to command line again and play second command.but python will wait for command line.

Hi dears.
I am playing windows commands with python scripts.
for example I did:

import os
print os.system("ipconfig -a")

but there is a problem with some commands.for example see this:

>netsh
netsh>dhcp
netsh>dhcp>scope 192.168.100.10

after playing the first one script, I have to come back to shell and play second one and ...
but how can I do it and also how can I do it in linux?

Hi dears.
I am searching around a reporter for python.
some thing such as crystal_report or stimul_report witch used for C# and some languages other.
thanks.

Thanks.I tried to get random number generating code from vs _by step debugging over "srand" function_ but it have used some registers from upper version than 8086 and it made me confused.
there is a problem at assemby86 function.it returns same sequence of random number every time.how we can improve it?

Sorry! is it pseudo code?
what are these? precision clock and !keyhit.

hi dears.
I am using Emu8086.
I need to generating an array of random numbers.
Are there any ready procedure or intrupt?
if there are not, how can I do it?
thanks.

So we have no private attribute as C++ in python.yes?
has python any thing about machine for hardware managmente or some thing like?
for example if we want to write a program that works on a set such as CNC or other sets such as this?

I tried to say my friend that python is as powerful as java.but they said me this problem.and the other was java's machine.it wor4k on every thing but python...
I don't know.I am using python since 2 years.I choosed it and I LOVE IT.
But we have to understand python's abilities.is not True.

I found that in python we have no realy private attributes.we just can use _ or __.but these are not deny access to my attributes.some thing such as private variables in c++.
Is it TRUE? Realy python is week in these?

lets Know more about my project.a corporation has a List of payments.
for example upkeep , digging and... .in each of them there are thousands factors and cheques witch have to add.some times they wants to add a new payment parameter into theme's list.I have no problem with theme's payments ID or adding them into my tables.
I have problem adding or deleting a new payment subject.
every of Costs Items are consider of many records.
I cannot read and write English good.It may be I say my mean wrong or find out your means wrong.Sorry If it is.

I have a code that plays fast _it's order is log(n)_.I have to meter it's play's elapsed time.I used from time.time() and time.clock() but they returned 0.I need a timer witch meter nano second.
How can I do it?

I have no problem in here.at first my change have to stores.for example the user wants insert a new cost to list.it will be add to the list compile time but at the next program playing my list is free.how i save it for my next plays.

other thing was my tables coulomns name.them's name is rely to the index of comboboxe's new item.
for example it has 3 cost in its list.
cost1
cost2
cost3
we removed the cost 2.
tables coulomn's name are
cost1
cost3
if we write the below code sqlserver will returns an error.and it is true.

sql = "ALTER TABLE tblCost cost";
      sql += cmbList.Items.count.Tostring() + " float";

because it want to add a new coulomn to tbl by name cost2.
while this name is exist.
I have to see at last item of combobox.here is cost3.
my new table's name have to be cost4.how can i earn it's name?

Hi Friends.
I have an project with vs2005 and sqlserver2005.There is a page contain a combobox , a text box and two button.The combox items are my cost list that maybe thems count increase by user.how can I manage it?

more about it:

if person clicks the add button we have to add textboxe's text as an item for combobox.
I did it like below:

cmbList.Items.Add(txtName.Text);

problem is that ofter programs running the added items have to remains for next play.How Can i save my new list for next plays?
And I have to add this item as a database's culomn which I did so:

sql = "ALTER TABLE tblCost cost"; 
sql += cmbList.Items.count.Tostring() + " float";

this sql command will plays.here is no problem.
so my tables culomns are named as items index's in my combobox and my tables culomns named as cost0, cost1, ... and new coulumns name is "cost"+(new indexe's number) _The items that added currently_.
the problem starts if the user delete one Item.so my combobox item's counts will increase and it makes error in altering the table.
so how can i improve it?

It worked.I forgot using the below code.

child.expect(pexpect.EOF, timeout=None)

Thanks alot.

sorry.I saw links but i can not solve my problem yet.
I say my problem again.it may be you found out it wrong.
At first I have not to do any thing in shell.
now I want change users password.I send the shell:

os.system("passwd %s" % username)

now shell wants me "Enter new password:" and i have to type it in shell.
but i have not do it.so i have to send the password in my code.but how can i do it?

I found my wrong.thanks alot.

Integrated Security = True

access to sql was denied without this.
or I have to make a user and password for a special user in sql server and in my code have to send as connection string to database.

but now I have a new problem.I have some text box and want send their values as string in to my database.I did it like below code:

sql = "Insert into specs (name, family)";
sql += "values ('{0}', '{1}')";
sql += string.Format(sql, txtName.Text, txtFamily.Text);

it is my string witch will be send to sqlserver.
but every time it makes 2 rows in my table.
one is consist {0} as name and {1} as family.
and other row is consist my real values.
how can i improve it and what is the common way?

I wrote below code for my database connection but every time its catch part play.what is the problem?

public myDb()
{
    canConnect = true;
    sqlString = "Connection Timeout=5;Server=127.0.0.1;Database=ghanat;";
    dbConnect = new SqlConnection(sqlString);
    dbCmd = new SqlCommand();
    dbCmd.Connection = dbConnect;
    dbAdapter = new SqlDataAdapter(dbCmd);

    try
    {
        dbConnect.Open();
        MessageBox.Show("You connected", "Connection", MessageBoxButtons.OK, MessageBoxIcon.Error);
    }
    catch
    {
        canConnect = false;
        MessageBox.Show("Connection Error", "Connection", MessageBoxButtons.OK, MessageBoxIcon.Error);
    }
    finally
    {
        dbConnect.Close();
    }
}

At the next step i have to send my sql string to database.
can you guide me or introduce me a clear brief Tutorial or an example project?

thanks alot.
