Python 3 is not backwards compatible with Python 2. Example: Python 2: print 'foo' Python 3: print(bar) Problem: Code written for Python during version 2 cannot be used/compiled in version 3 Solution: Just like any decent self-respecting programming language, add backwards compatibility. |

as stated in http://www.python.org/download/releases/3.1.2/ python 3 is designed to be backwards incompatible. I suggest you to follow the link "Conversion tool for Python 2.x code". |

> Code written for Python during version 2 cannot be > used/compiled in version 3 Use 2to3 script to convert your Python2 program to Python3. More information at: http://docs.python.org/py3k/whatsnew/3.0.html#porting-to-python-3-0 |

Python 2 is also forward compatible with several Python 3 features, for example:
>>> from __future__ import print_function
>>> print('foo')
foo
