| Python 1 | The release year of Python 2 is 2000 | The release year of Python 3 is 2008 |
| Python 1 | The syntax is more complex in this version than in Python 3 | The syntax is easy and simple |
| Python 1 | By default, strings are saved in ASCII format in version 2 of Python | By default, strings are saved in UNICODE format in this version. |
