对于大部分初学者来说，该选择Python2.x还是Python3.x？我想这个问题都是普遍初学者的疑问。我的回答当然是学Python3.x的啦。因为下面有段官方原话是这样子说的 ，大概意思呢就是Python 2.7将被支持到2020年，而且不会有2.8版本了，也就是说2.x的版本不再提供相应的服务。还说请用户尽快迁移到 3.4+以上版本。这点就充分的证明了更应该学Python3.x的理由。
- In November 2014, it was announced that Python 2.7 would be supported until 2020, and reaffirmed that there would be no 2.8 release as users were expected to move to Python 3.4+ as soon as possible
