    <p>I've been an avid learner of the Python language for quite some time. Having more than 6 years of Java[professional] experience, coupled with a bit of C++ [hobby] experience - it's fair to say my perspective is deeply entrenched in the idioms brought forth by such statically typed, strongly bound languages. In short - i could say the old school way of thinking has significant influence on my programming style.</p> <p>My reason to pick up Python, and not say Ruby, was primarily a coincidence since i got some part time work i could help out w/ using Python. it's been 2 weeks, and things have been nothing short of a revolution! armed w/ IDLE and the <a href="http://rads.stackoverflow.com/amzn/click/0672328623" rel="nofollow noreferrer">Python Essential Reference</a>, it's been one revelation after another. it's like how a classical physicist would feel if gravity ceased to exist!</p> <p>Anyways, i understand that to be effective w/ python it's going to take some time of real hands-on work. more than the syntax, i feel it's because of the way my mind thinks. however, prepared as much as i am, there's one particular thing which bothers me quite a bit - python offers way too many idioms to perform the same thing. For example, list comprehension and filter(...), apply(...) and eval(...), etc. while these idioms aren't completely substitutable, but i find that their primary purposes overlap to a great extent. i understand that there must be underlying performance gains vis-a-vis their usages. however, as a beginner, what's the best way to get on w/ the education and curb the distraction of 'n' ways to solve the same thing?</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.
