    <p>Background: I'm working with python 3.2 in Eclipse SDK 4.2.1 (Juno), and I noticed something strange - while my programs run perfectly in Eclipse, they always close with an error if I open them from the file manager. I managed to get a screenshot before the cmd closed: <img src="https://i.stack.imgur.com/4tlr1.png" alt="enter image description here"></p> <p>It seems that the program is inserting an additional "\" between "images" and "Cy.png". However, I can't just remove a slash from my program - in it, I used two slashes because you need to to include a slash in a string. My program is as follows:</p> <pre><code>from PIL import Image def pathConstruction(count, imageName): l = [] l.append('images\\') if count == 1: l.append('Sepia') l.append(imageName) imagePath = ''.join(l) return imagePath def grayscale(pix, width, height): for col in range(width): for row in range(height): r,g,b = pix[col, row] avg = ((r + g + b) / 3) r = int(avg) g = int(avg) b = int(avg) pix[col, row] = r,g,b def sepia(pix, width, height): for col in range(width): for row in range(height): r,g,b = pix[col, row] newR = (r * 0.393 + g * 0.769 + b * 0.189) newG = (r * 0.349 + g * 0.686 + b * 0.168) newB = (r * 0.272 + g * 0.534 + b * 0.131) pix[col, row] = int(newR),int(newG),int(newB) imageName = input("Please input the full name of your image, including extension: ") count = 0 imagePath= pathConstruction(count, imageName) count = count + 1 img = Image.open(imagePath) pix = img.load() width, height = img.size grayscale(pix, width, height) sepia(pix, width, height) imagePath = pathConstruction(count, imageName) img.save(imagePath) img.show() </code></pre> <p>Question: What can I do to run this program outside of Eclipse?</p>

    1. COyou could set `sys.excepthook` to a function that logs uncaught exceptions to a file. You can log to a file without waiting for the program to exit, setup: `logging.basicConfig(filename='example.log',level=logging.DEBUG)`, log: `logging.info('message')`.

    3. COConfigure logging and add `logging.debug(repr(imageName))` after `input()`. Do you see `\r` at the of image name in example.log?

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.
