Generally we encourage people to post what they've tried to the list. It
helps us identify what you know and what you need help with.
However, given:
the log file may not be always same so can not make static choices...
You'll probably want to use regular expressions:
https://docs.python.org/howto/regex.html
Regexps let you search through the text for known patterns and extract
any that match. To extract all SQL query sections, you'll need to come
up with a way of uniquely identifying them from all other sections.
Looking at your example log file, it looks like they're all of the format:
SQL Query [the actual sql query]
From that we can determine that all SQL queries are prefixed by 'SQL
Query [' and suffixed by ']', so the content you want is everything
between those markers. So a possible regular expression might be:
SQL Query \[(.*?)\]
To quickly explain this:
1. SQL Query matches on that string
2. Because [] have meaning for regexes, to match on literal
brackets you need to escape them via \[ and \]
3. ( ) is a group, whats contained in here will be returned
4. .* means to grab all matching text
5. ? means to do an ungreedy grab ie it'll stop at the first \]
it encounters.
Pulling the queries out of your log file should be as simple as:
import re
log = open('logfile').read()
queries = re.findall(SQL Query \[(.*?)\], log, re.DOTALL)
Because the queries can fall across multiple lines, the re.DOTALL flag
is required to treat EOL markers as characters.
Hope this helps.
Hi,
This helps and its working... Thank you so much

Code Review for Paper, Rock, Scissors
Hi all!
I'm new to Python and programming in general, and am trying to learn as much as
I can about it.
Anyway, for a basic first program I made a simple game of Paper, Rock,
Scissors. For this program, I incorporated a main menu that presented three
different options, allowed the user to play a game of Paper, Rock, Scissors,
allowed them to play the game again, and most importantly checked the user's
input to make sure the program doesn't fail due to errors.
One thing I want to try to add is a Press any key to continue function that
occurs at the end of the program when the user decides to quit. I looked at
some options online, but haven't quite figured it out yet.
As previously stated, I am new to Python and would also like to see if any of
you programming gurus have some suggestions about how I can simplify code, and
also if there are any other good starter programs to work on to improve my
skills.

You could halve that number if you converted your input to lowercase first.

I'm looking to start a team of developers, quants, and financial experts, to setup and manage an auto-trading-money-making-machine
I'm looking to start a team of developers, quants, and financial experts, to setup and manage an auto-trading-money-making-machine #1) Setup a VM; must be a Windows machine (maybe Azure) #2) Load configure the software (Matlab, Python, R, Excel, and SQL Server) #3) Develop and test code (Matlab or Pythonmost likely) #4) Hook into trading tool for order execution (system to be determined; depends on API) #5) Setup a corporate business structure (this is virtually done, we just need to flip a switch) #5) Shop around for clients (if we have a real money-making machine, this should be super-easy) Just so you know, I've done this kind of thing before, using Excel and VBA, as well as an execution program called Sterling Trader. It was quite profitable, and typically had less than 1 down day in a 22-trading-day month. The system was profitable about 95% of the time. However, I don't want to use Excel for this project; I want this to be a real system. I think we can use Matlab, or Python. If this is project turns out to be very profitable, I know we can raise capital very quickly and very easily. At the beginning, I believe it will take a fair amount of work, but if we put in the effort, we can have a system that constantly monitors the equity markets during trading hours, finds the best profit opportunities, according to the trading strategies that we deploy, and once it is setup and running, we really won't have to do a whole lot. Ideally, once you turn it on, the whole process will require almost no intervention. I know this can be done; many banks have groups that do exactly what I'm proposing here. The top hedge funds do this too. In conclusion, I think the trading strategies that we choose to employ should be easy to setup and test (a well-defined Google search will reveal countless trading strategies). I think getting the data should be pretty easy as well (we can load all kinds of indices into the tool). I think the hard part will be developing the automation processes; the tool will have to follow MANY rules and run all by itself. Finally, as neither Matlab nor Python are really execution tools, we'll have to connect to some type of system that allows us to send trade orders. This may, or may not, present somewhat of a challenge. As an alternative, if we decide we don't want to manage money for other people, we could setup the business as a subscription service, and charge users, let's say $25k/year or whatever, and let people run simulations in our hosted environment, and they can manage money themselves...we simply provide all kinds of analytic tools for them to do what they want to do.

Hi! Happy to help out. But first, there's one meta-suggestion that I'd
like to make: Use something other than Google Groups. As shown by the
line above, Google Groups has some issues with line breaks and text
wrapping; and it gets much worse when you reply to someone else's
post. I suggest using the mailing list instead:
https://mail.python.org/mailman/listinfo/python-list
Also, it can be helpful to state what version of Python you're using,
and on what platform. Your press any key to quit request suggests
you're probably invoking the script using a GUI, quite possibly
Windows, but that's far from certain; and as Dave's response shows,
the solutions depend on platform. I'm presuming you're using some 3.x
version of Python, as you use input() and print() functions, but I
can't tell whether you're on 3.2, 3.3, 3.4, or even an unreleased 3.5.
It's not likely to make a huge amount of difference with a script this
simple, but as a general rule, more information is better than less.
So, on to the code!
# Creates the main menu.
def menu():
# Sets the scores to 0.
global playerscore
global compscore
global draws
playerscore = 0
compscore = 0
draws = 0
You're importing these globals into several places that don't need
them. The menu shouldn't have to concern itself with these scores; you
could initialize them all to zero at top-level, and then keep the
different functions more self-contained. The displaying of the menu
doesn't logically involve zeroing out the scores; imagine making the
very slight (and quite logical) change of having the full menu
redisplayed after each game, instead of just having the Again? (Y/N)
prompt - suddenly your scores aren't getting carried over.
menuselection = input('Please enter a selection: (Play/Help/About): ')
# Checks for an invalid selection.
while menuselection != 'Play' and menuselection != 'play' and
menuselection != 'Help' and menuselection != 'help' \
and menuselection != 'About' and menuselection != 'about':
print('You have entered an invalid selection.')
menuselection = input('\nPlease type a selection: (Play/Help/About):
')
else:
if menuselection == 'Play' or menuselection == 'play':
play()
elif menuselection == 'Help' or menuselection == 'help':
instructions()
else:
about()
The else clause on a while loop isn't necessary here, because you're
not using break. All you need is to put your code outside the loop.
Alternatively, you can combine the verification and iteration into one
pass, which reduces redundancy and makes it easier to add more
options. I'm also incorporating some suggestions already made,
including Dave's dispatch dictionary.
func = {play:play, help:instructions, about:about}
while True:
menuselection = input('Please enter a selection:
(Play/Help/About): ').lower()
if menuselection in func: break
print('You have entered an invalid selection.')
func[menuselection]()
Note how the loop condition is now inside the loop (if ...: break),
with the while statement simply creating an infinite loop (while
True:).
def play():
# Player chooses Paper, Rock, or Scissors.
playerselect = input('\nPlease choose Paper, Rock, or Scissors: ')
Try to avoid comments that simply state what the next line(s) of code
do. At best, they're redundant; at worst, they're confusing, because
they can get out of sync with the code. Imagine adding a fourth option
(Claw Hammer) and forgetting to change the comment.
(Why claw hammer?
http://www.theregister.co.uk/2003/06/09/the_bastard_interviewer_from_hell/
)
import random
It's much more common to put your imports at the top of the script,
rather than inside a function.
# Creates the instructions.
def instructions():
print('\nPaper, Rock, Scissors is a simple game played against a computer
opponent.')
print('The player will have a choice of selecting paper, rock, or
scissors.')
print('The player\'s result will be compared with that of the computer to
determine who wins the round.')
print('In the event that both the player and the computer have the same
selection, the round will end in a tie.')
print('\nPaper beats rock but loses to scissors.')
print('\nRock beats scissors but loses to paper.')
print('\nScissors beats paper but loses to rock.')
print('\nGood luck, and have fun!\n')
menu()
As noted elsewhere, you have mutual recursion happening here. That's
not an advised technique in Python, as you can blow your stack
(there's no tail call optimization here). Much

I am building a simple podcast program where I download all the data from a feed with feedparser and store the data in sqlite3. I am spanking new to sqlite and database programming. Should I create the database in the __init__ method of my class, or is that a bad idea. I haven't done any designing that included databases. Thanks!

Short syntax for try/pass
Hi all, a lot of times the following pattern pops out in Python code: try: somecode except SomeException: pass A very simple example could be if you want to process a list that may be empty def process_list(lst): try: lst[0] = lst[0] + 1 except IndexError: pass or in more complex cases in which however an exception just signals that there is nothing to do there. Converting the code to a non-EAFP version, for example if len(lst) != 0: lst[0] = lst[0] + 1 is in my opinion generally against the Python nature, since it relies on a specific check on the object, instead of trusting the object as being able to either satisfy the request or raise an exception. That is, this solution is non-polymorphic. In such cases sometimes ABC may help, but generally speaking they it is not always the case of being an instance of a given ABC or not. The problem here is if the code raises an exception or not. Would it be feasible to propose a short syntax like this? pass SomeException: somecode where the above example would become: pass IndexError: lst[0] = lst[0] + 1 I could not find if such a syntax has been already discussed elsewhere, so please let me know if this is the case. Otherwise, what do you think about it?

I really have no idea what that means. You have 100 dicts of
dicts? Are the keys unique? If so, you could combine them with a
loop of update.
I tried using numpy.random.choice(), but it says it needs to be a 1-d array.
How about random.choice? It needs a sequence.
To get anything more concrete, you need to specify Python version,
and make a clearer problem statement, perhaps with example of
what you expect.

I'm going to make the wild assumption that you can safely do both
parses using regex, and that finding the jpegs works well enough
with your present one.
First thing is to make most of your present code a function
fetch(), starting with pagehtml and ending before the print. The
function should take two arguments, url and depthlimit.
Now, at the end of the function, add something like
If depthlimit 0:
matches = ... some regex that finds links
for link in matches [:40]:
fetch (link, depthlimit - 1)
Naturally, the rest of the top level code needs to be moved after
the function definition, and is called by doing something
like:
fetch (url, 10) to have a depth limit of 10.

stressing problem with Python 3.3.3 / 2.7.6 and Mac OS 10.9 Mavericks
Hi, I'm not a regular MacPython user, but today I had to build Mac wheels for different versions of Python. To test the wheel files I set up a fresh Mac OS 10.9 Mavericks and and installed Python 3.2, 3.3, 3.4 from the python.org download page on it. Then I struggled for the rest of the afternoon to try to figure out why Python 3.2 crashed when I used my package in interactive mode until I finally realized that it's not the package but Python that's responsible. Turns out that I had run into http://bugs.python.org/issue18458 which probably every MacPython user here is so familiar with that the download page doesn't even mention it ? ;) Seriously, I think the official download page for a OS shouldn't offer me a version that will not work well with the latest version of that OS without a warning. Why not add such a warning (like: versions below will crash in interactive mode on Mac OS 10.9) in the list of downloads at https://www.python.org/downloads/mac-osx/ between Python 2.7.6 (the first version with the issue fixed) and Python 3.2.5 (the last affected version).

I really have no idea what that means. You have 100 dicts of
dicts? Are the keys unique? If so, you could combine them with a
loop of update.
I tried using numpy.random.choice(), but it says it needs to be a 1-d array.
How about random.choice? It needs a sequence.
To get anything more concrete, you need to specify Python version,
and make a clearer problem statement, perhaps with example of
what you expect.

Hey DaveA,
I am using Python 2.7.
Yes. I have a dict of dicts with keys ranging from 1..100
And the value of each of these keys is another dict. What I need to do is make
3 smaller dicts and assign the values of keys 1..100 in the ratio 2:3:5.
For example, if my original dict is
d={1:{Key1:Value1, Key2:Value2, Key3:Value3},
2:{Key1:Value1, Key2:Value2, Key3:Value3},
3:{Key1:Value1, Key2:Value2, Key3:Value3},
4:{Key1:Value1, Key2:Value2, Key3:Value3}}
...
...
100:{Key1:Value1, Key2:Value2, Key3:Value3}
I need to have three dicts d1, d2, d3 with d1 containing the values of first 20
keys, d2 containing the values on next 30 keys and d3 containing the values of
the next 50.
Can you please help me with this?

You can get a list of the entries using the dict's .items method. It's
then a simple matter of slicing the list.
Note that dicts aren't ordered, i.e. its keys aren't in a fixed order,
so if you want then in a particular order, you'll need to sort the list.

Interpreting vague answer as: Yes!
If your program misinterprets a non-English response to an English

What have you actually tried? You haven't shown any actual code.
Look up the method dict.keys, and see how you might use that. Then
look up random.shuffle, and see what it would do. Also look up
dict.sort, since your two messages on this thread imply two
conflicting goals as to which sub dictionaries should go in which
of your buckets.
As for extracting 20% of the keys, slicing is your answer. If
there are 100 keys, 20, 30, and 50 need to be sliced
off.
Then you'll need a loop to build each result dictionary from its keys.
There are shortcuts, but it's best to learn the fundamentals first.
Try writing the code. If it doesn’t all work show us what you've
tried, and what you think is wrong. And when you get an
exception, show the whole traceback, don't just paraphrase one

Is there an easy way to control indents in Python
I'm just learning Python. It seems like indents are EXTREMELY important. I guess, since there are no brackets, everything is controlled by indents. Well, I'm reading a couple books on Python now, and in almost all of the examples they don't have proper indents, so when I copy/paste the code (from the PDF to the IDE) the indents are totally screwed up.

Yes that is what is in general expected out here -- code --
maybe working, maybe not, maybe incomplete, maybe 'pseudo' etc
Then others here will improve it
However there is one conceptual thing that perhaps should be mentioned: order.
Is your data *essentially* ordered?
And by 'essentially' I mean you think of it independent of python.
Yeah in python dicts are unordered and lists are ordered and one can fudge
one to behave a bit like the other. But before you fudge, please ponder which
you really need/want.
Below a bit of going from one to other
# dict - list
d = {a:1,b:2,c:3}
d
{'a': 1, 'c': 3, 'b': 2}
list(d)
['a', 'c', 'b']
# alternate
d.keys()
['a', 'c', 'b']
d.items()
[('a', 1), ('c', 3), ('b', 2)]
d.values()
[1, 3, 2]
# list - dict
dict(d.items())
{'a': 1, 'c': 3, 'b': 2}
# round-tripping
dict(d.items()) == d

[issue22627] Calling timestamp() on a datetime object modifies the timestamp of a different datetime object.
Antoine Pitrou added the comment: This has nothing to do with the datetime module. Attached script reduces the issue to a bug (?) in time.mktime() with the corresponding timezone. time.mktime() is a thin wrapper around the C library's mktime() function, so it is probably not a bug in Python at all. Note your script is fixed by removing .replace(tzinfo=None). It seems conter-productive to take the pain to create an aware timezone and then make it naive, IMHO. datetime.timestamp() falls back on time.mktime() when the datetime is naive (i.e. it asks the OS to do the computation).

[issue22630] `concurrent.futures.Future.set_running_or_notify_cancel` does not notify cancel
New submission from Ben Mather: The documentation for the `set_running_or_notify_cancel` method on `concurrent.futures.Future` states that it will notify waiting threads and trigger callbacks after the `Future` has been cancelled, however currently this is done immediately by the call to `cancel`. Oddly waiters (private interface used to implement `wait` and `as_completed`) do follow the behaviour documented for callbacks (they are called in `set_running_or_notify_cancel`) which means that they are not equivalent to setting a callback on each future. I have attached three possible patches: 1) change-callbacks.patch - this changes the behaviour to match the documentation. 2) change-docs.patch - this fixes the documentation to match the current behaviour. 3) change-docs-and-waiters.patch - in addition to fixing the documentation, this also fixes the inconsistency between waiters and callbacks by invoking waiters' `add_cancelled` method in `cancel`. I believe moving to the documented behaviour (1) would be a mistake as currently `set_running_or_notify_cancel` and the `RUNNING` state can be skipped entirely allowing Futures to be used just as a way to send results. Should mention that I have a separate patch (which I will submit separately (or here?)) that re-implements `wait` and `as_completed` using only publicly exposed methods. This makes it possible to extend or replace `Future` without having to preserve its private interface. Unfortunately this slightly breaks compatibility due to the difference between waiters and callbacks. I thought it would be best to discuss this issue first as I don't believe the current behaviour is as intended. -- assignee: docs@python components: Documentation, Library (Lib) files: change-callbacks.patch keywords: patch messages: 229282 nosy: bwhmather, docs@python priority: normal severity: normal status: open title: `concurrent.futures.Future.set_running_or_notify_cancel` does not notify cancel versions: Python 3.2, Python 3.3, Python 3.4, Python 3.5 Added file: http://bugs.python.org/file36908/change-callbacks.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22630 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22624] Bogus usage of floatclock in timemodule
Link Mauve added the comment: I’m building against the Newlib libc, for the Wii, and it seems the issue leading to all of those functions not working is: (.text.clock+0x18): undefined reference to `_times_r' Threading is disabled, and reentrant functions as well, which could explain that. But still, when pyconfig.h doesn’t define any HAVE_ macro to get the system time, I would expect py_process_time() to return None or something instead of failing to build. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22624 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1610654] cgi.py multipart/form-data
Serhiy Storchaka added the comment: I doubt we can use io.BufferedReader or handmade buffering here. Current code doesn't read more bytes than necessary. Buffered reader will read ahead, and there is no way to return read bytes back to the stream in general case (an exception is seekable streams). It can be blocked in attempt to fill a buffer with unnecessary bytes. I think that the user of the cgi module is responsible for wrapping a stream in io.BufferedReader (if it is acceptable), the cgi module shouldn't do this itself. But we can implement special cases for buffered or seekable streams. However this optimization will not work in general case (e.g. for stdin or socket). -- keywords: -easy stage: patch review - needs patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1610654 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue3068] IDLE - Add an extension configuration dialog
Saimadhav Heblikar added the comment: 1. Can we have more padding at the right end of the text widget? For me, it appears attached to the scrollbar. 2. Shortcut key for Configure extensions should be different from Configure Extensions. By this I mean, with the Options menu open, there is no way to open Configure Extensions using the keyboard.(Also see sidenote 1). 3. Is there a need for ... after Configure Extensions? I am asking this as don't know why it was there for Configure IDLE... in the first place. 4. User extension config files are created even if extension config settings are not dirty. Clicking OK or Apply without changing anything creates them. Even if I change the setting for only 1 extension, extension config for all extensions are written to disk. This is unlike the behavior of Configure IDLE dialog. 5. There are a couple of places where Ok and Cancel are used. If I have understood PEP8 correctly, aren't they not following it? Should they be ok and cancel instead? 6. Is there a reason to comment out the unittest and Htest in configDialog.py?(Other than application has been destroyed .. messages?) Sidenote 1 : Options menu unreachable via keyboard shortcut because both format and options have O as the keyboard shortcut. Sidenote 2: I am writing the review comments here as review tool does not detect all the files affected by this patch. Please confirm, so that I will post this issue to the developer list. -- Regards Saimadhav Heblikar -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue3068 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue8876] distutils should not assume that hardlinks will work
Matt Wright added the comment: Here's another example of where this is a pain. An emerging workflow is using Docker for a Python environment. However, on OS X, its common to use boot2docker (a lightweight VM). With VirtualBox on OS X, its common to setup a shared folder between the host and boot2docker so one can mount volumes to Docker containers from the host to the container(s) on the VM. So when running something like `tox` or `python setup.py sdist` things fail because VirtualBox does not allow hard links on the shared folder filesystem. Changing this would be grand. Otherwise I have the, arguably, ugly `del os.link` in my setup.py. -- nosy: +Matt.Wright ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8876 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
