Re: [Tutor] group txt files by month
hmmm thank you, I obviously need to put some more thought in first. Thanks for the responses.

[Tutor] I need Help
Hi, I am a new beginner/learner of Python. My first challenge is that I am unable to install the Python IDLE after downloading it from Python website. When I hit on the 'run' button, i got the error message below: "This installation package could not be opened. Contact the application vendor to verify that this a valid Window Installer Package." Furthermore, I read from the 'python for absolute beginners' text book that I need to add some code to the end of path in my computer property. Could this really be the solution to my problem? If it is, then I don't know how get such code to add. I don't know what to do. I use Windows 7 OS. Could someone help provide me a guide? Regards to all.

Hi Tavo, My responses are interleaved between your comments, shown with > markers. On 09/09/12 02:24, tayo rotimi wrote: Hi, I am a new beginner/learner of Python. Welcome and good luck! My first challenge is that I am unable to install the Python IDLE after downloading it from Python website. When I hit on the 'run' button, i got the error message below: "This installation package could not be opened. Contact the application vendor to verify that this a valid Window Installer Package." What are you downloading? As far as I can see, there is no installer for IDLE on the Python website. IDLE comes automatically with the rest of the Python installer. Please tell us: * what page you go to on the Python website to find this installer * which installer link you click on * the exact name of the installer file you download * whether your version of Windows is 32-bit or 64-bit Furthermore, I read from the 'python for absolute beginners' text book that I need to add some code to the end of path in my computer property. Really? Does it say what code to add, or will any old code do? Without knowing exactly what the book says, and the context, I have no idea what that means. -- Steven ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] I need Help
this is the same book i bought a few months ago to get me started. the instructions i remember where clear for windows. if there is a problem with the download files on the site, the author has the files on his own site also: http://www.programgames.com/page4.html save or run the file, once installed go to your start menu, choose All Programs, choose Python 3.1, then choose IDLE(Python GUI) ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
