Python programming philosophy
Hello, I want to learn working principle of python as broadly. How to interpret the python? For example, what is pyc files and when does it occur? Can you explain them? Thanks in advance. -- http://mail.python.org/mailman/listinfo/python-list

The pyc files aren't really a philosophical point, they're just a cache of the compiled versions of .py files - the assumption being that if you import it as a module once, chances are you'll import it again later, and libraries tend not to change much.

Re: Python programming philosophy
The compiler reads your source code and parses it into parse trees. This is first step. It then takes the parse trees and transform them into abstract syntax trees, which are like a DOM tree in an HTML file, and then transform that AST into a control flow graph, and finally a bytecode is produced out of that control flow graph. The pyc files you see are this bytecode, so they are produced at the end. Anytime you edit your .py file, a new .pyc file is created if you invoke the python interpreter myfile.py on the former. If your .py file doesn't change, the .pyc file stays the same. Just like with java, this allows you to write a single .py file that can work on any platform without changing the source file, because all the cross platform issues are handled by the virtual machine.

Java is still a fixed type computer language. -- http://mail.python.org/mailman/listinfo/python-list
Re: Python programming philosophy
The main philosophy behind python (according to me) is rapid application development. The python gives you convinent and powerful tool to develop sophisticated application rapidly. You can find more details on http://www.python.org/about/success/ http://www.python.org/about/success/#rapid-application-development Have a great python time. - Sourabh -- http://mail.python.org/mailman/listinfo/python-list
