    <p>I'm trying to learn python (using python3.2), and right now I'm creating a program designed to scale images:</p> <pre><code>from PIL import Image def newSizeChoice(): scale = input('Please enter the scale to be applied to the image: x') while float(scale) &lt;= 0: scale = input('Invalid: scale must be positive. Please enter a new scale: x') return float(scale) def bestFilter(x): if x &lt; 1: filter = 'ANTIALIAS' elif x == 2: filter = 'BILINEAR' elif x == 4: filter = 'BICUBIC' else: filter = 'NEAREST' return filter def resize(img, width, height, scale, filter): width = width * scale height = height * scale newimg = img.resize((width, height), Image.filter) newimg.save('images\\LargeCy.png') newimg.show() img = Image.open('images\\cy.png') pix = img.load() width, height = img.size scale = float(newSizeChoice()) filter = bestFilter(scale) resize(img, width, height, scale, filter) </code></pre> <p>It's a little bit of a mess right now, because I'm still working on it, but my problem is that when I set the filter in function 'bestFilter', I'm not able to use it to set the filter in function 'resize'. The error I keep getting:</p> <pre><code>Traceback (most recent call last): File "C:\Users\14davidson_a\Desktop\Projects\Exercises\ImageScaling.py", line 33, in &lt;module&gt; resize(img, width, height, scale, filter) File "C:\Users\14davidson_a\Desktop\Projects\Exercises\ImageScaling.py", line 23, in resize newimg = img.resize((width, height), Image.filter) AttributeError: 'module' object has no attribute 'filter' </code></pre> <p>Question: Is there a way I can use a string to set the attribute for a module?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
