The first really popular scripting language was Perl. Advocates of Python, often called pythonistas, say that Python is so clear and so enjoyable to write in that one should use Python for all of one's programming work, not just for scripting work. Background Needed Anyone with even a bit of programming experience should find the material through Section 8 to be quite accessible. The material beginning with Section 10 will feel quite comfortable to anyone with background in an object-oriented programming (OOP) language such as C++ or Java. Approach
