Not only it's *not a problem*. I've found it quite useful since it
forces you to keep the proper indentation.
Granted, the very first time I read about this feature, I've thought:
what a funny thing -- but then I've realized that since I keep the
proper indentation anyway, Python simply eliminates 'parenthetical
clutter' (in addition of forcing you to keep the code nicely
alligned).
For instance, in C I write
if (condition) {
statement-1
statement-2
}
else {
statement-3
statement-4
}
or some other coders prefer to write
if (condition) {
statement-1
statement-2
} else {
statement-3
statement-4
}
but in Python all those extra parenths are gone, and code is more
compact, more easily observable. you can squeeze more code into a
single displayble area which *is* important.
On the other hand, C has nothing that prevents someone from writing
the code:
if (condition) {
statement-1
statement-2 }
else {
statement-3
statement-4
}
Just had the situation a few weeks ago when novice C++ programmer
asked for help. Even if that programmer used emacs, somehow she has
managed to write the code as above. I simply told her to get her
identation in place first and then get back to me.
So: if you are a programmer who - as a matter of habit - writes nice
properly indented code, you will quickly appreciate the advantages of
Python (just like I did), and if you don't -- well, that's too bad.
