Question

Answer 1

+11 A:

Python doesn't have the increment (++) and decrement (--) operators, but it does have the += operator (and -=, etc.) so you can do this:

myInteger += 1
myString += "more text"

Yay me for never actually attempting += after finding that ++ wouldn't work...

@Teifion: and yay twice for never skimming through the Python documentation.

Side note: you should generally prefer ''.join(['some', 'more text', 'to add']) to += for strings with more than 2 components.

Answer 2

A:

You could do it in the same way you are doing it in PHP:

var += 1

But my advice is to write it down clear:

var = var + 1

I find the first one is WAY clearer. And it avoids a possible typo where you would accidently do something else than increment var.

PEZ 2009-01-11 22:13:25

var = var + 1 is not clearer.

I wouldn't down vote someone for saying it's subjective, but correct opinion.
