Blogger Carl Cheo, who maintains a website providing numbered lists of tips for maximizing online productivity, has pulled together an easy-to-follow graphic answering the newbie question "What programming language should I learn first?" (pdf here). Cheo chose nine commercially viable languages as possible destinations as the viewer navigates the flow chart. Further down the page, there are tabs with annotated links to educational resources for each language. So what's in it for Soylentils, most of whom I'm guessing were programming newbies in the previous millenium? Well, maybe you have nephews or nieces who chose the wrong major in college. Besides, the graphic is amusing and clever, though probably not the last word on the subject.

"Flexibility" is not a good thing for beginners, because it makes things more complicated. When there's 20 different ways to iterate over a list, it means you have to learn all of them, otherwise you won't be able to read other people's code. And having the freedom to indent however you want is a detriment for people who still haven't learned the importance of proper indentation.
Ruby and Python are both good choices for beginners, I just think Python's better. It's simpler, and it teaches good habits.

I get the reasoning, I just don't entirely agree. What good habits does Python teach? You get indentation at the cost of not learning to close blocks properly, that's a wash at best. You also get taught that if you aren't doing it the way the devs like then you're wrong. I don't see how that's a good habit, either. The forced indentation also interferes with code sharing unless everyone indents the same (usually PEP-8) way, going back to "do what the devs like or GTFO"
Good formatting is important, yes, but shouldn't be the primary reason to teach a specific language, especially in a controlled environment where you can have the instructor kick your ass for poor coding practices.
I'm not saying it's a terrible choice, and it's definitely far better than diving right into C or Java as a starter language. It's just that I don't think it's all rainbows and unicorn farts and the best teaching langauge ever like the smug pythonistas seem to think.

What? No it doesn't. It means you can learn all of them, not that you must. Certain ways are more common and, especially if you're using something like Perl's camel book or Ruby's pickaxe book, the style should be consistent throughout. Realistically you'll only be learning one way, at least at first.
I wasn't talking about Perl-style "there's 50 ways to do it, all of them unreadable" anyway. That's why said flexible syntax, and mentioned optional parentheses as an example of what I meant, though it also includes things like requiring semicolons at end-of-line. I think reducing unnecessary punctuation is a good thing, especially when it allows English-like constructs. For example, a Ruby if/else without parentheses:
if a == b then
print "match"
else
print "no match"
end
Even without more than the vaguest understanding of programming it should be readable and can cleanly parsed in English. "if a equals b then print 'match', else print 'no match'. End." Python get some of it (no semicolons), but it's more strict about parentheses in other places and makes you litter colons around instead of sticking to words.
It doesn't seem like a big deal if you're already familiar with other languages, but if you're picking up these fundamentals for the first time, it helps if they can be represented in an English-like way. (I happen to like Perl's "unless" statement for if-not-equals stuff for similar readability reasons, but wouldn't necessarily throw it at a newbie right off)

That's what I was originally taught about C in the class I took back in college — if we didn't write code in the same nebulous style the instructors preferred, we'd only get partial credit for our work even if the program performed perfectly. Our final exam was even multiple choice, with "which of these is written the right way" type questions with a partial focus on style. (Suffice to say I felt lucky that I got a C in the class.)

At least with an instructor, after the class is done you can adjust your style to your liking. In that way it's sort of like martial arts; while learning, you have to do what the teacher wants, but inevitably it gets changed to suit you, sometimes only slightly, sometimes greatly. It's harder to do that when the "my way or the highway" is baked in, which is what I don't like about Python. There's plenty to like about the language, but it just has this authoritarian feel to it in some ways that I don't care for and would find unappealing as a learning language.

Of course you got a C. It was a C class, after all.
