[Tutor] Help IDLE Compile Problem
Hi,I have two Python source files within editing them via IDLE.I have a problem. The second file is used by the first file. Some partsi mean from the second file is used. But when i change the contents of the second file and while i'm running the first file with F5, change doesnt reflectto the runtime. If i close two IDLE windows and delete .pyc of the second filethen it is ok. What is the problem ? ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
[Tutor] IDLE Caching
Hi,I have a problem with IDLE on Windows.While I'm executing a python script in IDLE subsequenceediting and executions on the file sometimes doesn't reflect the changes.For example, i changed the file then save it, execute it, although i changed the file, IDLE shows the previous version of the file. If I close and run the IDLEthen it correctly shows the execution of the current source file. What will bethe problem ? ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

class Tree: def Tree(self): self.rootNode = None def Tree(self, rootNode): self.rootNode = rootNode def getRootNode(self): return self.rootNode def setRootNode(self, rootNode): self.rootNode = rootNodeclass Node: def Node(self): self.content = '' self.isleaf = False self.childnode = None self.label = '' def setContent(self, content=''): self.content = content def getContent(self): return self.content def setLeaf(self, leaf): self.isleaf = leaf def isLeaf(self): return self.isleaf def setChild(self, childnode): self.childnode = childnode def getChild(self): return self.childnode def setLabel(self, label=''): self.label = label def getLabel(self): return self.label t = Tree()n = Node()look at this code. Edit this code with IDLE. For example change one of the 'self' statementin the code. For instance change self => slf then save the file and press F5(Run Module) It doesn't complain about the code !!! this is my problem. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] IDLE Caching
Really, I have realized the difference Luke said. However sometimes IDLE runs theold version, this is the thing I cant realized.On 7/24/06, Luke Paireepinart <[EMAIL PROTECTED]> wrote: [snip code]> look at this code. Edit this code with IDLE.

To the compilerit makes no difference. Do you still think it's a problem with IDLE? ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] IDLE Caching
So from the answers, i want to imagine how python exercise the codewhen you push the button execute. My guess before looking at the docsor other material,1. check python syntax 2. transform to byte code.3. execute the byte code. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] IDLE Caching
let me dig into documentation before thinking in the blind :) thanks a lot Alan !On 7/25/06, Alan Gauld < [EMAIL PROTECTED]> wrote:> So from the answers, i want to imagine how python exercise the code > when you push the button execute.

What you have is correct for a main program.If its a module being imported there is a slight difference:0) check if module already loaded, if yes stop1) check if a pre-compiled version already exists 2) check if the source file is newer3) if newer compile code to byte code and save pyc file4) import byte codeThis is described in more detail in the documentation.Alan GauldAuthor of the Learn to Program web site http://www.freenetpages.co.uk/hp/alan.gauld ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Hi,My thought is seperate main and utility functions to different files.For example there will be a Main.py and UsbUtil.py and from Main.pyyou can import usb functions. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
