Brackets or not to Brackets

[meddyliol]

Most (if not all) online Python tutorials do not use brackets, for example: print "Hello", if I do this with the raspberry it gives a syntax error. Of course writing: print("Hello") does work. Is there a reason for this? I thought that Python did away with using brackets.

I think that is the difference between python 2 and python 3.

(I'm not a Python programmer, but I've seen it mentioned before)

[DougieLawson]

Parentheses are needed for python3.

You're using python2 if it works without.

s/brackets/parentheses/g

+1

Brackets being the square ones [] and braces being the curly ones {}.

So what are ( and )?

So what are ( and )?

As indicated above (my first post on this thread):

parentheses

Note that some of the text above is what they call a "parenthetical".

[jamesh]

Nope.

All the above are brackets according to the English definition...because they all 'bracket' something...so the OP is actually correct in his use of the word brackets. If not particularly specific.

Brackets: ()
Curly brackets: {}
Square brackets: []
Quotey things: ""

While technically true, the request "please help me with my words because my little computer doesn't do what I want" is equally accurate (and difficult to process).

Oh dear. English is losing to Merriam & Webster's egregious American Standard definitions. All is lost, I'll blame Facebook for that.

Let me put up a quick translation guide, based on rpdom's post:

Code: Select all

British            Symbol   American

Brackets            ()   Parentheses
Curly brackets      {}   Curley Braces
Square brackets     []   Brackets
Quotey things       ""   Quotation Marks
?                   ''   Single Quotes
?                   <>   Angle brackets (if used as brackets. Otherwise Less Than and Greater Than)
?                   #    Pound Sign or Hash
?                   ~    Tilde

I thought braces were what all those US teenagers have on their teeth? But I use braces to hold my trousers up
.
"Er, what are trousers"?

Oh, pants!

Pants from the spanish pantaloons.

Really?

Pretty sure Oxford University Press are fairly British English.

All very enlightening, but to get back to helping the enquirer:

Most (if not all) online Python tutorials do not use brackets, for example: print "Hello", if I do this with the raspberry it gives a syntax error. Of course writing: print("Hello") does work. Is there a reason for this? I thought that Python did away with using brackets.

" I thought that Python did away with using brackets."

Quite the contrary. The move from python2 to python3 made their use mandatory in some situations where they were optional before. print is probably the most obvious example.

[Tarcas]

Pound sign (weight) lb/℔ Huh? Do you mean #?
Pound sign (money) £ Do you mean dollars?

We use lb or # for pounds weight. (usually in the grocery store you'll see prices in $/lb rather than $/#, although I have seen the latter, but usually on hand-written signs.)

I think most of us know what a £ is. But good response nonetheless.

[meddyliol]

Thank you all for your informative answers. I think you have answered my question Along with lots of other must know stuff

Cheers

P.S. Wasn't that a rather retrograde step going from Python 2 to 3 and putting brackets () back in? Everywhere online seems to do without brackets ().

[chrisryall]

I can't think for the life of me think why either. This in a language that uses vacuous and tab-indistinguishable "white space" to control the more inportant "flow"

In there with those anal ';'s at the end of every line in C (or the Algol group). Javascript is cool on the issue and nothing seems to fall off
