Pyserial for Python3 in OSX?
I need to do some serial I/O on a Mac running OSX Mavericks. I followed the instructions at http://stackoverflow.com/questions/20082935/how-to-install-pip-for-python3-on-mac-os-x to install pyserial. OSX already had Python 2.7 and pyserial seems to work okay in 2.7, but I can't figure out how to get to run in 3.3.3 or 3.3.4. After I install pyserial, in python 2.7 I can get this: Python 2.7.5 (default, Sep 12 2013, 21:33:34) [GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> from serial.tools import list_ports >>> list_ports.comports() [['/dev/cu.Bluetooth-Incoming-Port', 'n/a', 'n/a'], ['/dev/cu.Bluetooth-Modem', 'n/a', 'n/a'], ['/dev/cu.usbserial-AH012QEW', 'FT232R USB UART', 'USB VID:PID=403:6001 SNR=AH012QEW']] >>> quit() In Python 3, I get this: Python 3.3.4 (default, Feb 15 2014, 21:28:44) [GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.2.79)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> from serial.tools import list_ports >>> list_ports.comports() [] >>> quit() I see all sorts of messages around the web suggesting similar problems getting Python 3 on a Mac to talk to serial ports but I can't find any fixes. Is there a trick I haven't found yet? Many thanks in advance for a cure. Howard -- https://mail.python.org/mailman/listinfo/python-list
IDLE won't run after installing Python 3.3 in Windows
The next adventure in Python was to install Python 3 into a Windows XP machine. I had a previous 2.7 installation that I uninstalled and carefully removed all traces of from the directory and the registry. I got the 'python-3.3.3.msi' from Python.org and installed it. From a command window I can run 'python' and I get the Python prompt. I have several Python programs on the machine. If I right click o one, I have the option of 'Edit in IDLE'. If I do that, the disk light blinks briefly, and then nothing. So I went into the \python33\lib\idlelib directory and from a CMD window, ran 'python idle.py'. That loads IDLE. but when I ask IDLE to load a file, it navigates to a FileOpen dialog and then closes everything when I actually open the file. I then tried the same thing but used 'pythonw' instead. Same deal. I also saw some other threads here about how Python can get befuddled by firewalls, so I disabled that with no effect. Any suggestions? Thanks in advance! Howard -- https://mail.python.org/mailman/listinfo/python-list

After the registry was purged of everything and I deleted the directories, I restarted the machine to make sure the registry was read afresh (Windows XP is wacky that way) and then did a reinstall of Python 3.3.3. Before installing anything else, I launched a program by using the 'Edit in Idle' option. Idle comes up, flashes briefly and exits. The console window never appears. If I bring up a command window and go into the lib\idlelib directory and specifically start idle with "python idle.py" or "pythons idle.py", I get Idle, but no command window. Load a file in if launched with 'python', it appears but you can't run it. If you launch with 'pythons', the whole kit & caboodle just exits when you load the file. That might not help, but that's all I saw. Is there someplace not obvious in the registry where any interesting information is kept? -- https://mail.python.org/mailman/listinfo/python-list
