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) ...
这篇文章主要介绍了相比于python2.6,python3.0的新特性。更详细的介绍请参见python3.0的文档。 Common Stumbling Blocks 本段简单的列出容易使人出错的变动。 print语句被print()函数取代了,可以使用关键字参数来替代老的print特殊语法。例如: Old: print "The answer is", 2*2 ...
