However you need to enter exactly Quit and not QUIT or quit or any other combination... It usually better to force the user input to upper or lower case, eg: while m.lower() != quit: 2nd How can I make this program not crash when a user enters a non integer? m = raw_input(“Enter an integer: “) while not m.isdigit(): m = raw_input(“Enter an integer: “) num = int(m) Moving the last line out of the loop will help. But there are other things to check in addition to isdigit(). That's why Python tends towards exception handling rather than pre-validation. eg. while True: try: m = int(raw_input()) except ValueError,TypeError: continue HTH -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
[Tutor] urllib.urlretrieve ?
Im following a tutorial on what i believe is using Python 2 and i'm a bit confused. I use Python 3 on windows vista. I believe urlretrieve() is a python 2 function that isnt in 3, but why is the tutorial using urllib instead of urllib2? Also when i run the program on Python 3, it says: AttributeError: 'module' object has no attribute 'urlretrieve' so Python 3 doesnt recognize this function, i want to ask if there is an equivalent function to 'urlretrieve' in Python 3? the program uses this function to download a file as so: urllib.urlretrieve(self._url, self._filename, reporthook) the 3rd argument is a function that is called to track progress of the current download status. i dont really need help with the program, i understand its code, but i need to know if this function has one similar in Python 3? or do you have any examples of how i could add its functionality to Python 3. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] urllib.urlretrieve ?
the whole program depends on the urlretrieve 3rd argument, the function to be called.. is there no options to include a callback? def _download(self): def reporthook(pos, block, total): if self.size != total: self._size = total self.on_size.emit() self.progress = float(pos*block)/float(total) urllib.urlretrieve(self._url, self._filename, reporthook) ##3rd arg calls inner function self.running = False ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] urllib.urlretrieve ?
Look in the module docs for urlib.request. Hi. Ive never used the urllib before unless it was typing in something from an unrelated tutorial. I've also never done anything related to web programming. I'm looking at the urllib.request page and i really don't understand what i'm looking at. I'm confused as to what i should be looking for. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] urllib.urlretrieve ?
You might want to look at requests module: http://docs.python-requests.org/en/latest/ Many people think it is easier to use than the native python support. are all of these modules related to web programming like clients and (HTTP)servers? I've come across urllib a lot of times but only followed along, maybe its best i just learn about HTTP and its concepts etc so i can understand the request module better then come back to my problem..

Re: [Tutor] urllib.urlretrieve ?
yeah, sadly urlretrieve doesnt exist on my version of python. i just need a function to put in the same line that replaces this one with the same arguments in order to see the results of my tutorial. urllib.urlretrieve(self._url, self._filename, reporthook) On Sun, Apr 7, 2013 at 7:10 PM, Alan Gauld alan.ga...@btinternet.com wrote: On 07/04/13 17:20, Matthew Ngaha wrote: Look in the module docs for urlib.request.
