Use [`shutil.rmtree`][1]:

    import shutil

    shutil.rmtree(path)

See [the documentation][2] for details of how to handle and/or ignore errors.


  [1]: http://docs.python.org/library/shutil.html#shutil.rmtree
  [2]: http://docs.python.org/library/shutil.html#shutil.rmtree

The standard library includes [shutil.rmtree](http://docs.python.org/3/library/shutil.html#shutil.rmtree) for this. By default,

    shutil.rmtree(path)  # errors if dir not empty

will give `OSError: [Errno 66] Directory not empty: &lt;your/path&gt;`.

You can delete the directory and its contents anyway by ignoring the error:

    shutil.rmtree(role_fs_path, ignore_errors=True)

You can perform more sophisticated error handling by also passing `onerrror=&lt;some function(function, path, excinfo)&gt;`.

You want [shutil.rmtree][1]

&gt; shutil.rmtree(path[, ignore_errors[,
&gt; onerror]])
&gt;
&gt; Delete an entire directory
&gt; tree; path must point to a directory
&gt; (but not a symbolic link to a
&gt; directory). If ignore_errors is true,
&gt; errors resulting from failed removals
&gt; will be ignored; if false or omitted,
&gt; such errors are handled by calling a
&gt; handler specified by onerror or, if
&gt; that is omitted, they raise an
&gt; exception.

I recently came to git for a project I participate to. I found git gui rather handy (under OSX Snow Leopard) to srtat with but I would much like if it were not localized (in French, in my case). Is there preference or hack to have git gui displayed in english?

How do I delete a possibly non-empty dir in Python.

The directory may have nested subdirectories many levels deep.

I have a command line program in Python that takes a while to finish. I want to know the exact time it takes to finish running.

I&#39;ve looked at the `timeit` module, but it seems it&#39;s only for small snippets of code. I want to time the whole program.


How do I get time of a Python program&#39;s execution?

My application looks like this:

&lt;pre&gt;
main.py
windows/
    __init__.py
    mainwindow.py
    ...
model/
    __init__.py
    orders.py
    ...
resources/
    image1.png
    logo.jpg
    ...
&lt;/pre&gt;

The program is started with main.py. Is there a good way to create a &#39;final&#39; application out of it? I&#39;m thinking of something like py2exe/py2app, but without copying the python interpreter / modules into the application where one has only one executable.

I had a look at distutils, but this looks like it installs a program into the Python directory, which isn&#39;t usual on non-linux platforms.

At the moment I just copy the whole source folder onto the target machine and create an alias to `main.pyw` on windows. Some inconveniences:

 * The icon is the default python icon.
 * I have to create the alias manually.
 * In my source directory there are a lot of additional files like the source control folder.
 * I have to rename `main.py` to `main.pyw` manually.
 * It would be nice if only `.pyo* files are on the target machine. There&#39;s no real reason for it, I just don&#39;t like having unnecessary files.

How does one create a nice automated distribution?

 * for windows? (That&#39;s the only platform that I have to support at the moment.)
 * for mac?
 * for linux?

How do I exclude entire files from [coverage.py][1] reports?

According to the documentation you can exclude code by matching lines. I want to exclude entire files, so that the reports don&#39;t include 3rd party libraries. Am I missing something? Can it be done?

In JavaScript, one can print out the definition of a function.  Is there a way to accomplish this in Python?  

(Just playing around in interactive mode, and I wanted to read a module without open().  I was just curious).  

Can Python print a function definition?

The following code works:

    class Foo(tuple):
    
        def __init__(self, b):
            super(Foo, self).__init__(tuple(b))
    
    if __name__ == &#39;__main__&#39;:
        print Foo([3, 4])
    
    $ python play.py 

Result:

&lt;!-- language: lang-none --&gt;

    play.py:4: DeprecationWarning: object.__init__() takes no parameters
      super(Foo, self).__init__(tuple(b))
    (3, 4)

But not the following:

    class Foo(tuple):
    
        def __init__(self, a, b):
            super(Foo, self).__init__(tuple(b))
    
    if __name__ == &#39;__main__&#39;:
        print Foo(None, [3, 4])
    
    $ python play.py 

Result:

&lt;!-- language: lang-none --&gt;

    Traceback (most recent call last):
      File &quot;play.py&quot;, line 7, in &lt;module&gt;
        print Foo(None, [3, 4])
    TypeError: tuple() takes at most 1 argument (2 given)

Why?

When using files in Ruby, what is the difference between the `r+` and `w+` modes? What about the `a+` mode?

Difference between the access modes of the `File` object (ie. w+, r+)

I am trying to figure out if there is any difference in performance (or advantages) when we use nio `FileChannel` versus normal `FileInputStream/FileOuputStream` to read and write files to filesystem. I observed that on my machine both perform at the same level, also many times the `FileChannel` way is slower. Can I please know more details comparing these two methods. Here is the code I used, the file that I am testing with is around `350MB`. Is it a good option to use NIO based classes for File I/O, if I am not looking at random access or other such advanced features?

    package trialjavaprograms;
    
    import java.io.File;
    import java.io.FileInputStream;
    import java.io.FileOutputStream;
    import java.io.InputStream;
    import java.nio.ByteBuffer;
    import java.nio.channels.FileChannel;
    
    public class JavaNIOTest {
    	public static void main(String[] args) throws Exception {
    		useNormalIO();
    		useFileChannel();
    	}
    
    	private static void useNormalIO() throws Exception {
    		File file = new File(&quot;/home/developer/test.iso&quot;);
    		File oFile = new File(&quot;/home/developer/test2&quot;);
    
    		long time1 = System.currentTimeMillis();
    		InputStream is = new FileInputStream(file);
    		FileOutputStream fos = new FileOutputStream(oFile);
    		byte[] buf = new byte[64 * 1024];
    		int len = 0;
    		while((len = is.read(buf)) != -1) {
    			fos.write(buf, 0, len);
    		}
    		fos.flush();
    		fos.close();
    		is.close();
    		long time2 = System.currentTimeMillis();
    		System.out.println(&quot;Time taken: &quot;+(time2-time1)+&quot; ms&quot;);
    	}
    
    	private static void useFileChannel() throws Exception {
    		File file = new File(&quot;/home/developer/test.iso&quot;);
    		File oFile = new File(&quot;/home/developer/test2&quot;);
    
    		long time1 = System.currentTimeMillis();
    		FileInputStream is = new FileInputStream(file);
    		FileOutputStream fos = new FileOutputStream(oFile);
    		FileChannel f = is.getChannel();
    		FileChannel f2 = fos.getChannel();
    
    		ByteBuffer buf = ByteBuffer.allocateDirect(64 * 1024);
    		long len = 0;
    		while((len = f.read(buf)) != -1) {
    			buf.flip();
    			f2.write(buf);
    			buf.clear();
    		}
    		
    		f2.close();
    		f.close();
    		
    		long time2 = System.currentTimeMillis();
    		System.out.println(&quot;Time taken: &quot;+(time2-time1)+&quot; ms&quot;);
    	}
    }

 


Java NIO FileChannel versus FileOutputstream performance / usefulness

I am building an application (on windows using Dev-C++) and I want it to download a file. I am doing this using libcurl (I have already installed the source code using packman). I found a working example (http://siddhantahuja.wordpress.com/2009/04/12/how-to-download-a-file-from-a-url-and-save-onto-local-directory-in-c-using-libcurl/) but it doesn&#39;t close the file after download is complete. I would like someone to give an example on how to download a file, either in c or c++. Thanks in advance!

I want to open a file for reading. However, in the context of this program, it&#39;s OK if the file doesn&#39;t exist, I just move on. I want to be able to identify when the error is &quot;file not found&quot; and when the error is otherwise. Otherwise means I need to quit and error.

I don&#39;t see an obvious way to do this with `fstream`.

---
I can do this with C&#39;s `open()` and `perror()`. I presumed that there was a `fstream` way to do this as well.

[File-like objects][1] are objects in Python that behave like a real file, e.g. have a read() and a write method(), but have a different implementation from `file`. It is realization of the [Duck Typing][2] concept.

It is considered a good practice to allow a file-like object everywhere where a file is expected so that e.g. a [StringIO][3] or a Socket object can be used instead a real file. So it is bad to perform a check like this:


    if not isinstance(fp, file):
       raise something

What is the best way to check if an object (e.g. a parameter of a method) is &quot;file-like&quot;?
