[Tutor] POST request using httplib2
On the way of learning " handling POST request in php" i tried to make a
simple python http client using httplib2 & urllib module.. what i wanted to
do was submitting username & password field to a php script (which just
echo's the username & password) & prints the response in python,not in
html/php..
import httplib2
import urllib
url="http://localhost/form_process.php";
body={'username':'xyz','password':'abc'}
h=httplib2.Http()
response,content=h.request(url,'POST',urllib.urlencode(body))
print content
I got the following content:
*
Form processing
:
*
instead of:
*
Form processing
xyz: abc
*
attachments:
form.php # takes username,password from the user,pass those to
# form_process.php as GET parameter
form_process.php # echo username,password.
sorry for my long email.

Re: [Tutor] Python GUI
Just to add to what Alan's said: A key thing you will need to wrap your head around when transitioning to GUI applications is the fact that the application is then not linear (or as linear) as a console/text application. In a console application you basically control everything, and if there needs to be a loop in the application to repeatedly collect user actions or events (such as menu selections and so on) etc, then it's up to you to write this yourself. GUI applications are however different, in that the entire GUI system is "event driven". Conceptually what this means is that operating system is ultimately responsible for collecting events (such as mouse clicks, keyboard input, and so on) and it delivers these events/actions to your application by sending it messages (which ultimately translates into functions and methods in your application being called, as if by magic, from the outside.) The upshot of this is, as Alan said, that in most GUI applications you don't write loops to "wait for input" yourself, you instead hand this off to the operating system. And it knows to call your methods by the fact that in some part of your application you "register your interest" in receiving various events, typically by providing an event handler (a method to be called when that event happens.) So conceptually, in a console application, you write the "main" loop yourself, and directly call other methods/functions when certain "events" happen (such as the user selecting a menu option.) In a GUI application, you can imagine this loop is somewhere inside the operating system (not inside your application), and so your application doesn't provide one itself, instead your application collaborates with the operating system to make your application happen. Object orientation conceptually is all about objects collaborating with other objects by sending and receiving messages, collectively working towards a solution. Hope that helps.

Re: [Tutor] Python GUI
"David Merrick" wrote Others have answered the immediate issue. But... def testNumber(self): guess = int(self.numberEnt.get()) tries = 1 while guess != the_number: if guess > the_number: number += "Lower..." else: number += "Higher..." guess = int(self.numberEnt.get()) tries += 1 This is all wrong for a GUI appluication. You should not use loops in an event handler. Instead let the event loop in Tkinter do the looping. You respond to the user clicking the submit button and evaluate that single value. You then wait for the next button press to signal that there is a new value to check. Any time you see a loop inside a GUI event handler you should stop and check that it belongs there. Usually it doesn't! number += "You guessed it! The number was" + the_number number += "And it only took you " + tries + " tries!\n" self.numberTxt.delete(0.0, END) self.numberTxt.insert(0.0, number) It may just be mail but this appears to be outside the method definition and indeed outside the class. Is that correct? Or just a mail glitch? Since they refer to self they should be inside a method so I'll assume its a mail thing. # main number = "" the_number = random.randint(1, 100) If you are using classes its normal to put most of the variables inside the classes. There is no reason for the_number to be a global value, it would be better as part of the Application.
