2. Quotes Perl is worse than Python because people wanted it worse - Larry Wall, Creator of Perl Python fits your brain - Bruce Eckel, Author: Thinking in Java Python is an excellent language & makes sensiblecompromises. - Peter Norvig. AI Life is better without brackets 3. About Python very clear, readable syntax portable intuitive object orientation natural expression of procedural code full modularity, supporting hierarchical packages very high level dynamic data types extensive standard libraries and third party modules forvirtually every task extensions and modules easily written in C, C++ (or Java forJython, or .NET languages for IronPython) 4.
