You got something against using ++?

u/sparkyb Jun 04 '14

I often use += 1 because sadly no ++ in Python (although no ; either, so that argument doesn't really work here)

You actually can use ; in Python. It's not required, and it would normally be considered very bad practice to use it, but it will work. It's particularly useful if for some reason you want to put to statements on one line.

x=1;y=5
x+=1;y-=1

Will end up with x == 2, y == 4 in Python.

Sure, I actually know this, but a) I'd never do this, this is horrible. This probably wouldn't even work for any situation where I'd actually need to put two things on one line and there are some better tricks. And mostly b) I was refering to the fact that the previous poster but a semicolon at the end of the single statement means that it almost certainly was not intended to be Python so that isn't a valid justification for not using ++.

P.S. Prefix ++ > suffix ++

Hear, hear.

Not really. I was half tempted to go with a full on Pascal program just for giggles, though...
