It is like releasing window Xp SP3 even if Vista is out.<div><br></div><div>The problem is we should start using python 3.x but many application like django, twisted had not migrated yet. Hence this stuff to support 2.x . 2.7 is the last 2.x version, no more.<br>

Hi all,<br>
I am just curious: if Python3.x is already out, why is 2.7 being<br>
released? Are there two main types of Python? Thanks.<br>

Old code and old programming habits may work as-is with 2.7 but not with a 3.x implementation.<br>
<br>
So yes, there are two main extant variants of Python, 2.x and 3.x (and more if you count even earlier versions).<br>
<br>
2.7 helps to ease the transition, and provides bug-fixes and better efficiency for the 2.x variant.<br>
