filehandler

问题 Currently I am trying to open a text file called "temperature.txt" i have saved on my desktop using file handler, however for some reason i cannot get it to work. Could anyone tell me what im doing wrong. #!/Python34/python from math import * fh = open('temperature.txt') num_list = [] for num in fh: num_list.append(int(num)) fh.close() 回答1: The pythonic way to do this is #!/Python34/python num_list = [] with open('temperature.text', 'r') as fh: for line in fh: num_list.append(int(line)) You

问题 I wrote a small-ish Python script that handles nightly conversions and archiving of audio data. Since there have been some unexpected problems along the way (non-existing files, unreliable connection to the database server and so on...), I added Python's own logging facility to keep track of any encountered problems. The problem is, the log file is created wherever the script is run from (e.g. current working directory), so I have two logfiles, one in my homedir (which is used when the script

问题 So I have been able to take a multi-page TIFF file and convert it to a single jpeg image but it flattens the TIFF. By flatten it, I mean it only returns the first page. The goal is to retrieve the TIFF (via memory stream), open each page of the TIFF and append it to a new jpeg (or any web image). Thus creating one long image to view on the web without the aid of a plugin. I do have the MODI.dll installed but I am not sure how to use it in this instance but it is an option. Source Code (using

问题 I'm trying to use CFBundleDocumentTypes to associate a custom file extension with my application. As far as I can tell, this seems to "work" -- JavaApplicationStub launches my application when I double click the file. However, no callback is registered through the ApplicationListener events I setup in java. I used the code listed in Set Default file association Mac OS X Java Package Maker Installer to do the file association, and the file association itself appears fine, but it seems as if it

问题 First, a simple test code: package javaapplication23; import java.io.IOException; import java.util.logging.FileHandler; public class JavaApplication23 { public static void main(String[] args) throws IOException { new FileHandler("./test_%u_%g.log", 10000, 100, true); } } This test code creates with Java 7 only one File "test_0_0.log", no matter, how often I run the program. This is the expected behaviour because the append parameter in the constructor is set to true. But if I run this sample

问题 I don't know how to handle my FileHandler on API REST I have a REST API installed at Weblogic, I'm using Java Logging and when my app starts, inits the logger, and open the FileHandler. Like i never close the FileHandler the .lck file that is created stays at my logs folder. I really don't care the presence of that file, but when i redeploy the app, like the FileHandler is still open, my app starts a new log file (ex: myLog.log.0 , myLog.log.1 ). I have read that JVM itself should be closing

问题 I have a persistent event-driven HTTP upload program (hot folder) that writes to a log on every action. It runs indefinitely until the user decides to close it. To ensure the log is closed when the application is closed, I have written the program so on every write to log, it opens the log file, writes to it, and then closes the log. Like so: fh = new FileHandler(logName, true); fh.setFormatter(new MyCustomFormatter()); logger.addHandler(fh); logger.info(message); logger.removeHandler(fh); fh

问题 I'm using gvim 7.3, MS-Windows 32-bit GUI version with OLE support I'm attempting to configure the netrw filehandler to open locally saved .html files in with the elinks browser, rather than the firefox browser. The help file for netrw refers to a setting that can be placed in the .vimrc file: :let g:netrw_browsex_viewer= " " it also says that 'for Windows 32 or 64 the url and FileProtocolHandler dlls are used'. I've tried entering the filepath to the elinks executable between the quotes, but
