python3.0使用字符串(strings)和bytes代替Unicode字符串和8位字符串,这意味着几乎所有使用Unicode编码和二进制数据的代码都要改动。这个改动很不错,在2.x的世界里,无数的bug都是因为编码问题。 map()和filter()返回迭代器(iterators) dict方法keys(),items(),values()返回视图(同样是迭代器)而不是列表(list) 内...

dict methods dict.keys(), dict.items() and dict.values() return “views” instead of lists. For example, this no longer works: k = d.keys(); k.sort(). Use k = sorted(d) instead (this works in Python 2.5 too and is just as efficient). ...

How do I identify the insertion point in a text document? In most text editors or word processing software, the insertion point is usually represented by a blinking vertical line or a caret symbol. You can typically see it on the screen as you type or move it using the arrow keys on yo...
