Shorthand adding/appending in Python

python

提问by Teifion

I like that in PHP I can do the following

我喜欢在 PHP 中我可以执行以下操作

$myInteger++;
$myString += 'more text';

With Python I must do the following

使用 Python 我必须执行以下操作

myInteger = myInteger + 1
myString = myString + "more text"

Is there a better way to add or append to a variable in Python?

有没有更好的方法在 Python 中添加或附加到变量?

回答by Jeremy Ruten

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

Python 没有递增 (++) 和递减 (--) 运算符,但它有 += 运算符(和 -= 等),因此您可以这样做:

myInteger += 1
myString += "more text"

回答by hyperboreean

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

你可以像在 PHP 中那样做:

var += 1

But my advice is to write it down clear:

但我的建议是把它写清楚:

var = var + 1
