问题 I have just installed Macports for a short course I am planning to do. IDLE does not open whether I launch it from Terminal or Finder. Just for clarification, I am issuing idle2.7 to launch it from terminal.

问题 In IDLE, there's no clear screen, and after reading the forums the best method is plainly to print a ton of "\n"s. However, after playing with IDLE, I made a discovery. When my game was waiting for an input after printing out instructions using print statements, instead of inputting any useful character, I entered 'control-z,' and IDLE began to remove the text that was display by the print statements, one by one. My main question is, how do I manually in the code itself enter 'control-z', so

问题 When I open Python's IDLE, sometimes and error name 'port binding error' is accrues, and IDLE is filed to run on the computer. one this error accrues, it will repeat every time I'll open IDLE, till the computer will be restarted. the error box saies: ' ILDE can't bind to a TCP/IP port, which is necessary to communicate with its Python execution server. This might be because no networking is installed on this computer. Run IDLE with the -n command line switch to start without a subprocess and

问题 I've got a quick question, but I can't find an answer. Is it possible in linux (or in python) to see if an external usb pen drive is idling? I need to know this for a python script I'm writing. I need to rename a folder on an external usb pen drive as soon as nothing is writing to it. edit: I know there is lsof command to list open files. 'lsof /theDir' only works half. It works OK when the process copying to the USB is still running. But when the process stops, lsof shows nothing. But the OS

问题 Ok, I realize this may be an extremely nuanced question, but it has been bugging me for a while. I like the simple scripting interface of IDLE, but it keeps crashing on me when: (1) I am coding on an external monitor and (2) I type the parenthesis button, "(". IDLE never crashes for me for any other reason than this very specific situation. Strangely, if I have an external monitor connected, but I have the IDLE dev window on my laptop's main screen, I have ZERO problems with crashing. (???) I

问题 Writing to a file prints integers to my IDLE shell. They seem to range from 15-40 and there's one for every line printed to my file. This only occurs if I write the statement directly in IDLE, outside of a function. This causes the integers to print: >> file = open('filename', 'w') >> for element in list: file.write('{}\n'.format(element)) while this doesn't: >> def print_to_file(): file = open('filename', 'w') for element in list: file.write('{}\n'.format(element)) file.close() >> print_to

问题 Since upgrading to Windows 10 I can no longer print from the IDLE Python IDE. The "print to default printer" box comes up as usual, but nothing is sent to the print queue ... I checked in Devices & Printers. Printing from other applications works fine. 回答1: I confirmed on my Win10 machine. However for me, the problem is not with Win 10. It is a stupid bug that I introduced in 2.7.11, 3.4.4, and 3.5.1. I am assuming that you must have upgraded Python also. You can test if you have the same

问题 I have code using tkinter which I can run from IDLE just fine, but which throws the exception AttributeError: 'module' object has no attribute 'font' when it is run from the command line. Other tkinter programs work fine, but anything using the tkinter package's font.py gives me this error. I've checked my python files and c:/Python34/Lib/tkinter/font.py is there. I am not sure why, from the command line, it thinks font is an attribute and not a module of the tkinter package. Example code:
