Intro To Python
Python is an interpreted language, which can save you considerable time during program development because no compilation and linking is necessary.
The interpreter can be used interactively, which makes it easy to experiment with features of the language, to write throw-away programs, or to test functions during bottom-up program development.
Python programs are more readable*, compared to most of the other programming languages.
Other programming Languages can be WRAPPED by Python!
