loops
I'm just getting into py coding, and have come across an oddity in a py
book - while loops that don't work as expected...
import random
MIN = 1
MAX = 6
def main():
again = 'y'
while again == 'y':
print('Rolling...')
print('Values are: ')
print(random.randint(MIN, MAX))
print(random.randint(MIN, MAX))
again = input('Roll again? (y = yes): ')
main()
Produces -
python dice_roll.py
Rolling...
Values are:
5
4
Roll again? (y = yes): y
Traceback (most recent call last):
File "dice_roll.py", line 17, in
main()
File "dice_roll.py", line 15, in main
again = input('Roll again? (y = yes): ')
File "", line 1, in
NameError: name 'y' is not defined
This same loop structure appears in many places in this book "Starting
out with Python, 2nd ed, Tony Gaddis), and they all yield the same
error. Is there something I'm missing here?
Thanks for the input...

smtp
I'm working on learning various aspects of Py coding, and happened to review
the smtplib docs this morning.
I entered the sample code from
http://www.python.org/doc//current/library/smtplib.html
import smtplib
def prompt(prompt):
return raw_input(prompt).strip()
fromaddr = prompt("From: ")toaddrs = prompt("To: ").split()print
"Enter message, end with ^D (Unix) or ^Z (Windows):"
# Add the From: and To: headers at the start!msg = ("From: %s\r\nTo: %s\r\n\r\n"
% (fromaddr, ", ".join(toaddrs)))while 1:
try:
line = raw_input()
except EOFError:
break
if not line:
break
msg = msg + line
print "Message length is " + repr(len(msg))
server =
smtplib.SMTP('localhost')server.set_debuglevel(1)server.sendmail(fromaddr,
toaddrs, msg)server.quit()
and it returns -
"TypeError" with no other information...
It appears to be generated from the line
msg = ("From: %s\r\nTo: %s\r\n\r\n"
% (fromaddr, ", ".join(toaddrs)))
But I'm not sure why...
Any input is appreciated.

It didn't seem to matter what is input -
I tried using a single recipient as well as multiples (separated by comma).
Output appears as -
# python send_my_msg.py
From: m...@me.com
To: y...@you.com
Enter Message, end with ^D:

I think it may depend on the level of expertise you're at. WingIDE is my preferred choice since it offers a lot of help in developing Py, has a solid debugger, and is available across platforms. But I'm a novice Py coder. If you're already strong in the coding sense, vi is my editor of choice, which I use for other languages that I'm intimately familiar with. Wiki has a pretty good comparison of Py coding editors/IDEs (wiki search Python development tools). Like many other things Linux, it's all about choice. Being a non-free IDE is not a major drawback to Wing (imo). Price is decent, support is excellent, and upgrades are included through major versions (4 just came out recently). There's also a sizeable community of people using it. I don't know a whole lot about the company, but it may be one person. Seems every time I've called I've spoken to same person - not too easy to understand, but he is very helpful and seems to really know his way around the tool.

Each one is also uniquely set to match a set of criteria of my own choosing to indicate level of data, level of composite data, level of integrity, level of criticality, and a few other 'soft values'. This equates to each account being generated in a one-off fashion, so I'm not worried that my list account here will ever show up somewhere else in any other form. However, that doesn't mean that it doesn't concern me that the list is publishing these values back to the list participant(s) in plaintext. If I have to unsubscribe and then re-subscribe without a pass-phrase I can do that but just wanted to make the list admin(s) aware that it had occurred. -- Regards Jack Boston Tea Party, Coercive Acts, Powder Alarm, Revolution Lessons (Mistakes) not learned are bound to be repeated. -- https://mail.python.org/mailman/listinfo/python-list

Py and SQL
All
I have a sql script that I've included in a simple Py file that gives an
error in the SQL. The problem is that the SQL code executes correctly in a
database IDE environment (in this case ora developer). So, I'm concluding
that I'm doing something amiss in the Py code. Does anyone see why this
code would return a 'missing expression' sql error?
Essentially, the code should start, ask for a privilege, and then collect
the priv, role, and user data. Any input is appreciated.
#!/bin/bash
import time
import cx_Oracle
dbConn = cx_Oracle.connect('juser', 'pass', '1.2.3.4:/orcl:DEDICATED',
cclass = "ABC", purity = cx_Oracle.ATTR_PURITY_SELF)
pStart = time.time()
dbVersion = dbConn.version.split(".")
majVer = dbVersion[0]
print "Oracle Version: %s" %(majVer)
print "Full Version: %s" %(dbConn.version)
dbCursor1 = dbConn.cursor()
dbCursor1.execute('select lpad(' ', 2*level) || c "Privilege, Roles and
Users" from ( select null p, name c from system_privilege_map where name
like upper(\'%&enter_privliege%\') union select granted_role p, grantee c
from dba_role_privs union select privilege p, grantee c from dba_sys_privs)
start with p is null connect by p = prior c')
dbRowResult = dbCursor1.fetchall()
for dbRow in dbRowResult:
print dbRow
dbCursor1.close()
pElapsed = (time.time() - pStart)
print pElapsed, " seconds"
dbConn.close()

dpkt
Hi I'm looking to find some help working with dpkt. As you probably know, there really isn't any documentation, and not being astute at Python as of yet leaves me with a lot of gaps. Is there anyone here that can point me in a direction toward writing some test code for parsing gre packets? Thanks for the input; I appreciate the help.

Data is indexed and stored in flat files. For a personal app that maintains a small footprint, it's relative performance is acceptable. If the number of entities and attributes rises above a handful, however, I would recommend investing more thought in whether this is a permanent solution.

The fact is that I don't _want_ to, but need to as a part of a work project. If I had a choice, base 64 would be the way to go since (as you point out), it's already in the standard library. If I could take the encoded form and translate it to base 64 and then use the standard library, that would work as well, but I'm not sure that there's a one-to-one correlation there. - Jack -- http://mail.python.org/mailman/listinfo/python-list

The link you sent will (hopefully) give me a starting point.

For the cost, it has nearly everything I've seen in Netbeans for Java. I believe a license is about $80(USD) and is well worth the money (at least to me). Runs on win, lin, and mac. The auto-complete and function/method/lib/package helpers are invaluable to me since I haven't memorized everything within the python libs. - Jack > > -- > Stanley C.
