And when I execute it, it keeps running forever and I don't get any email.

[...] I want my script to start at a given time and stop at another given time, is that possible? The right solution to this is probably to use your operating system's scheduler to run your script at whatever time or times you want. Under Unix/Linux, that is cron. I'm sure Windows will have it's own, but I don't know what it is. Then your script then doesn't have to care about times at all, it just runs and does its thing, and the OS controls when it runs. cron is amazingly flexible. This is the proper separation of concerns. Your script doesn't have to deal with memory management, or the file system, or scheduling times, that is the operating system's job. The OS already has tools to do this, and can do them *much better than you*. (What happens if your script dies? What about when the time changes, say because of daylight savings?) Unless you are running on some primitive OS with no way to control when jobs run except to manually run them, the *wrong* solution is a busy-wait loop: while True: # Wait forever, doing nothing. sleep(0.1) # Yawn. if now() == some_time(): do_this() It doesn't matter if you use the sched module to shift the time check to another part of your code if the main loop does nothing. The critical question here is this: While you are waiting for the scheduled time, does your main loop continuously do any other work? If the answer is Yes, then using sched is the right approach. If the answer is No, then your main loop is just killing time, doing nothing but sleeping and waiting, like somebody checking their wristwatch every two seconds. You should simplify your script by getting rid of the main loop completely and let your OS handle the timing: # No loop at all. do_this() Thanks. That was a great answer. I'll redo my code. It's running and will only run in my Docker container (Ubuntu Server 14.04.1) so I'll use cron.

Also the Worker thread sends a signal with the data, so there's no need to check worker.trades and risk it being invalid data. Perhaps this would be more what you had in mind. You may want to look into asynchronous I/O as well. That does not require threads at all. Fire off a request to load a url, and then get a callback when it's done. Now it's working like a charm without any freezes. I'll reproduce this 'Worker' for other stuffs that I need to call the web, but first I have a question. Which one would be better in performance, having a single 'Worker' to call all URLs, having inside this worker functions for each stuff, or having 3~5 different workers doing different stuff. In the end I'll only print the data when I have them all. The problem is that I would have a long new_value = Signal(QThread, str, str), with more then 10 values, is it possible to pass objects here like new_value = Signal(QThread, ObjA, ObjB, ...) so that in the 'create_topic' I would get the objects and call methods in order to get all the data? This approach would be better, because I may be adding more stuff and I wouldn't need to add tons and tons of new stuff in my signal, only one object.

The main.ui is a XML, http://pastebin.com/Eq9hNMBX , just save it as

What I have in mind is simple (I think), have the Outpost get the data
using QThread, and when it got everything needed emit a signal. So when I
have something like 'var = Outpost('123')', when I get the signal I'll know
that I can call 'var.trades, var.posts' and it won't give me NullErrors or

So, instantly I found one issue, you said that this code won't block the
GUI, only the thread event loop, but if we keep moving the window while
it's open, every time new info is printed the GUI freezes for like 1-2
seconds.
And why this approach of a single instance is better? I mean, I'll have to
call Outpost every time I get new data from my other API, because there
will be different users, so I need to create different instances so I call
the site with a new ID, don't I?
Maybe the answer for that question is that you using a timer that is ALWAYS
active and ALWAYS calling the the outpost site, so I'll have something like:
var = Outpost('12345')
var.posts - 100
var.setID('67893')
var.posts - 35
Is that right? But I don't think that always calling the site this way is
good for them and for me, sometimes I may not get new users for like 10~15
minutes, so I would have wasted a lot of calls for nothing. That's why I
only instantiate/call the site when I get new users.

Re: Fwd: Python Signal/Slot + QThred code analysis
So guys, I had to change to approach, I read that using Qt I can't do
multiple inheritance. So my Outpost class can't be like 'Outpost(QObject,
QThred)'. I had to change the code a bit:
from PySide.QtCore import QObject, QThread, Signal
import requests
import bs4
class Worker(QThread):
def __init__(self, url, *args, **kwargs):
super().__init__(*args, **kwargs)
self.trades = None
self.posts = None
self.url = url
self.start()
def run(self):
soup = bs4.BeautifulSoup(requests.get(self.url).text)
self.trades = soup.select('div.stat_box
div.value')[0].get_text().replace(',', '')
self.posts = soup.select('div.stat_box div.value')[1].get_text()
return self
class Outpost(QObject):
received = Signal()
def __init__(self, id64, *args, **kwargs):
super().__init__(*args, **kwargs)
worker = Worker('http://www.myurl.com/' + id64)
self.received.emit(worker)
So, what I see people doing is creating a 'Worker' class for thread related
stuff and another separate class for the main stuff.
So, let's see the problems:
Traceback (most recent call last):
File D:/.../main.py, line 44, in output_slot
outpost = Outpost('12345')
File D:\...\outpost.py, line 27, in __init__
self.received.emit(worker)
TypeError: received() only accepts 0 arguments, 2 given!
The URL is OK, I externally checked, and return the expected.
So, what I'm trying to do here is call my Worker when outpost is
instantiated, then the Worker call the site in the run function, and then
set the variables and return itself.
Back to the main class, I have the init where I instantiate the Worker and
return it in the emit().
If I got it correctly, when I call the 'outpost.received.connect(IPSUM)',
IPSUM will be execute when, and only when I have all values set, because in
my Outpost class it will emit when it has everything done, did I get it
right?

stuffs, is it OK now?

Python Signal/Slot + QThred code analysis
This is a continuation of my other topic How to access Qt components
loaded from file, it was getting big and the focus changed completely, the
real question there was already answered, and we were talking about
signal/slot, QThred and other things.
So, I read on the web (didn't find books talking about QThred, Signal/Slot)
and I came up with this code:
Python 3.4.2
PySide 1.2.2
from PySide.QtCore import QObject, QThread, Signal
import requests
import bs4
class Outpost(QObject, QThread):
received = Signal()
def __init__(self, uid, *args, **kwargs):
super().__init__(*args, **kwargs)
self.url = 'http://www.myurl.com/user/' + uid
def run(self):
soup = bs4.BeautifulSoup(requests.get(self.url).text)
with soup.select('div.stat_box div.value')[0].get_text().replace(',',
'') as a, soup.select('div.stat_box div.value')[1].get_text() as b:
self.info_a = a
self.info_b = b
self.received.emit(self)
Is this code good?
I'll explain what I think this code does, when I was doing this: First I
created my custom signal, 'received'. Then I made my __init__ just to set a
uid.
Then, the run func, I read that's the one that will run when working with
threads. Here I set the soup and I get the page content using requests,
that's the part that will take more time.
Then I use bs4 to set my data, and yes, I know that getting data this way
isn't the best option, but I don't have other choice, they don't give APIs
for this stuff.
Later I emit my signal when I have everything set and I pass the entire
class with it so I can call the 'var.info_a' and 'bar.info_b' wherever I
want.
Did I think correctly, can I do anything better here? Many thanks.

Let's say that I want to call the site in a 5min interval. I'm currently getting the info this way just for testing and to know that the 'core engine' is working, and indeed, it's working: if __name__ == __main__: import sys app = QApplication(sys.argv) MainWindow = loadui(main.ui) def output_slot(): MainWindow.txtbox.setText(call_site()) MainWindow.btn.clicked.connect(output_slot) MainWindow.show() app.exec_() How can I proceed if I want the txtbox to automatically do the 'setText(call_site())' in a X defined interval? The final app will have not only a txtbox, but a complete interface with buttons, avatar image, some txtboxes, and all that stuff. If I know how to call the site in a defined interval, I can get all the info that I need and set them one by one. If I'm not mistaken my app is locked in the app.exec_() loop, so I need to have a trigger configured that will be called in a defined interval, then inside this trigger I configure the set_avatar, set_text, set_btn_link, etc, is that right?

Thanks, it's working using QTimer. The thing is that whenever the program is going to do something, in my case, draw a new QGroupBox with some components inside and put it in the Form (I'm using VBoxLayout in the main form) the program freezes, and I'm using very simple components just for testing.This shouldn't be normal, right?

You can't have a slot like this: MainWindow.btn.clicked.connect(MainWindow.txtbox.setText(test())) because that's mean: connect to the return of MainWindow.txtbox.setText(test()) and it's not possible at this stage of your program. Use instead a function: MainWindow.btn.clicked.connect(my_slot) # No parenthesis ! def my_slot(): MainWindow.txtbox.setText(test()) Thanks, it's working.

PySide 1.2.2 setMaxWidth and AeroSnap
PySide 1.2.2 Python 3.4.2 Code: from PySide.QtGui import * class MainWindow(QWidget): def __init__(self): QWidget.__init__(self) self.setMinimumSize(600, 700) self.setMaximumWidth(600) self.setLayout(QVBoxLayout()) * Call to this module in another module * app = QApplication(sys.argv) window = MainWindow() window.show() app.exec_() When I set the setMaxWidth I can't use the Windows AeroSnap anymore, why? I didn't set a setMaxHeight, so this shouldn't lock me from doing the snap.

Not having ever attempted to go beyond even the basics of Perl, the

to be a small step towards Perl.
Some people do not like Python's indentation rules but for me it's a
large part of what draws me to program in Python. Spaces for indentation
and blank lines are both aspects of how I like to program.
I write in Python because I like to, not because I have to.
I think the only reason I might code a function with no blank lines was
if I was programming in a language that using blank lines caused it to run
too slowly.
So to be clear, I'm not talking about taking a function like this

Rather, I'm saying that where the blank line is should be the start of
a new function. There would still be a blank line, just no longer
inside the function.
Now, maybe you think there should be more blank lines in the above, in
which case we'll just have to disagree on that point.
By the way, I didn't test that at all, which is why I've spotted at
least two bugs in it since sending the message.

Some prefer verbal material, others prefer more visual, while some others like written material. The vast majority however prefer a combination of the above. While you can pour over tutorials on how to use Emacs; just watching a video of a power user using Emacs gives you a different impression. It is really a completely different experience. Sometimes it is faster to produce a set of video tutorials than to prepare well-written documentation. Hence they make a call. However, I agree that written documentation is the best medium for long term (i.e. smaller, searchable etc) So, rather than asking for one medium of instruction to stop, I would rather encourage the plurality. Let the end-user pick and choose whatever he/she likes. As the guy said, and many others in the comments agree, rather than asking for one medium of instruction to stop, I would rather encourage the plurality., and indeed, I prefer plurality, I DO use the official doc, I don't only see video-tutorials. You don't know me, you don't know my learning process, so stop imposing what YOU think is right, because what's right for YOU won't necessarily be for others. No matter what you say, it won't change, don't try to standardize the learning process, you nor anyone can do this. The thing is, it’s text.

Also note that this construct tends to be particularly sensitive to

many (which your editor may well do for you to helpfully match it up
with the if), then you'll get a completely different result.
I would not worry about the else clause as a beginner, as it's
relatively unique to Python and tends to be somewhat confusing. Use a
flag or refactor the function instead.
