I&#39;d start by using glob:

    from PIL import Image
    import glob
    image_list = []
    for filename in glob.glob(&#39;yourpath/*.gif&#39;): #assuming gif
        im=Image.open(filename)
        image_list.append(im)

then do what you need to do with your list of images (image_list).

    from PIL import Image
    import os, os.path

    imgs = []
    path = &quot;/home/tony/pictures&quot;
    valid_images = [&quot;.jpg&quot;,&quot;.gif&quot;,&quot;.png&quot;,&quot;.tga&quot;]
    for f in os.listdir(path):
        ext = os.path.splitext(f)[1]
        if ext.lower() not in valid_images:
            continue
        imgs.append(Image.open(os.path.join(path,f)))
       


In objective-c I can just say the following. 

    [self.promoTextField setKeyboardType:UIKeyboardTypeEmailAddress];

I tried googling it but just get ways to do it in objective-c.

Anyone know how to clear the selected value of an ui-select box in angular?

I want the functionality of select2 where you have a small x in the selectbox. Doesn&#39;t look like it&#39;s got the allow-clear method that select2 got.

I am trying to import all the images inside a directory (the directory location is known).  

    path = /home/user/mydirectory


I already know a way of finding out the length of the directory.
  
What I&#39;m not sure about is how I can import the images (using `PIL/Pillow`) into either a list or a dictionary, so they can be properly manipulated.

I am trying to use the Requests framework with python (http://docs.python-requests.org/en/latest/) but the page I am trying to get to uses javascript to fetch the info that I want. 

I have tried to search on the web for a solution but the fact that I am searching with the keyword javascript most of the stuff I am getting is how to scrape with the javascript language.

Is there anyway to use the requests framework with pages that use javascript?

I am following instructions for a class homework assignment and I am supposed to look up the top 200 most frequently used words in a text file. 

Here&#39;s the last part of the code:

    fdist1 = FreqDist(NSmyText)
    vocab=fdist1.keys()
    vocab[:200]


But when I press enter after the vocab 200 line, it returns:

     Traceback (most recent call last):
     File &quot;&lt;stdin&gt;&quot;, line 1, in &lt;module&gt;
    TypeError: &#39;dict_keys&#39; object is not subscriptable


Any suggestions on how to fix this so it can correctly return an answer?

How do you create a virtualenv for a specific python version using ansible. Is there a command in the ansible standard library?

I would like something like:

I am using selenium for end to end testing and I can&#39;t get how to use `setup_class` and `teardown_class` methods.

I need to set up browser in `setup_class` method, then perform a bunch of tests defined as class methods and finally quit browser in `teardown_class` method. 

But logically it seems like a bad solution, because in fact my tests will not work with class, but with object. I pass `self` param inside every test method, so I can access objects&#39; vars:


    class TestClass:
      
        def setup_class(cls):
            pass
            
        def test_buttons(self, data):
            # self.$attribute can be used, but not cls.$attribute?  
            pass
            
        def test_buttons2(self, data):
            # self.$attribute can be used, but not cls.$attribute?
            pass
            
        def teardown_class(cls):
            pass
        

And it even seems not to be correct to create browser instance for class.. It should be created for every object separately, right?

So, I need to use `__init__` and `__del__` methods instead of `setup_class` and `teardown_class`?

How do I correctly setup and teardown for my pytest class with tests?

In an ipython notebook, I used a matplotlib stylesheet to change the look of my plots using 

    from matplotlib.pyplot import *
    %matplotlib inline
    style.use(&#39;ggplot&#39;)

My version of matplotlib is 1.4.0. How do I go back to the default matplotlib styling? I tried all the available styles in

    print style.available 

but there doesn&#39;t seem to be a &quot;default&quot; option. I also tried 

    matplotlib.rcdefaults() 

For some reason, this gives me a gray background. It also changes the text from gray (ggplot style) to black, which may be the default, but also could be another random style.

The single line that I am trying to run is the following:

    from PIL import Image

However simple this may seem, it gives an error:

    Traceback (most recent call last):
      File &quot;C:\...\2014-10-22_12-49.py&quot;, line 1, in &lt;module&gt;
        from PIL import Image

        from PIL import VERSION, PILLOW_VERSION, _plugins
    ImportError: cannot import name &#39;VERSION&#39;

In case that&#39;s helpful, I installed pillow from https://pypi.python.org/pypi/Pillow/2.6.1 (file `Pillow-2.6.1.win-amd64-py3.4.exe`) before running this (before that there was already som `PIL` install, which I uninstalled). The script is run in Pyzo with Python version 3.4.1.

What is going wrong, how can I import `Image`?

Why can&#39;t Python import Image from PIL?

This is my code

    from PIL import Image
    pil_im = Image.open(&#39;data/empire.jpg&#39;)

I would like to do some image manipulation on it, and then show it on screen.   
I am having problem with showing PIL Image in python notebook.    

I have tried:

    print pil_im

And just

    pil_im

But both just give me:

    &lt;PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=569x800 at 0x10ECA0710&gt;

I want to resize an image in pillow-python, however I have 2 functions of choice to use:


`Image.resize` http://pillow.readthedocs.org/en/latest/reference/Image.html#PIL.Image.Image.resize

**and** 

`Image.thumbnail`
http://pillow.readthedocs.org/en/latest/reference/Image.html#PIL.Image.Image.thumbnail


Both definitions point out to resizing the image,  Which one should I be using?

I am trying to horizontally combine some JPEG images in Python.

## Problem
I have 3 images - each is 148 x 95 - see attached. I just made 3 copies of the same image - that is why they are the same.

![enter image description here][1]![enter image description here][2]![enter image description here][3]

## My attempt
I am trying to horizontally join them using the following code:

    import sys
    from PIL import Image
    
    list_im = [&#39;Test1.jpg&#39;,&#39;Test2.jpg&#39;,&#39;Test3.jpg&#39;]
    
    # creates a new empty image, RGB mode, and size 444 by 95
    new_im = Image.new(&#39;RGB&#39;, (444,95))

    for elem in list_im:
        for i in xrange(0,444,95):
            im=Image.open(elem)
            new_im.paste(im, (i,0))
    new_im.save(&#39;test.jpg&#39;)

However, this is producing the output attached as `test.jpg`.

![enter image description here][4]

## Question
Is there a way to horizontally concatenate these images such that the sub-images in test.jpg do not have an extra partial image showing?

### Additional Information
I am looking for a way to horizontally concatenate n images. I would like to use this code generally so I would prefer to:

 - not to hard-code image dimensions, if possible
 - specify dimensions in one line so that they can be easily changed

Combine several images horizontally with Python

I have a python file with the Pillow library imported. I can open an image with

    Image.open(test.png)

But how do I close that image? I&#39;m not using Pillow to edit the image, just to show the image and allow the user to choose to save it or delete it.
