Python 3 Programming

Target audience:
This course is suitable for programmers starting new projects in Python 3, or for those porting existing applications from Python 2.

• No previous knowledge of Python is assumed, although delegates should be familiar with at least one programming language.
• Experience of another scripting language, such as Perl or PHP, will be an advantage, as will previous experience of object oriented programming.
