- 13. Python as Research Workbench Pythonmakes it easy to balance high-level programming with low-level optimization. Python excels at gluing other languages. Numerous libraries provide the needed functionality for scientific. Python incorporates documentation and testing directly into the language itself. 組內報告 2012/10/30 13

- 25. The Python Paradox, by Paul Graham • You could get smarter programmers to work on a Python project than you could to work on a Java project. • If a company chooses to write its software in a comparatively esoteric language, they'll be able to hire better programmers, because they'll attract only those who cared enough to learn it. • The language to learn, if you want to get a good job, is a language that people don't learn merely to get a job. 組內報告 2012/10/30 25
