- What is Python? Executive Summary
- ----------------------------------
-
- Python is an interpreted, object-oriented, high-level programming
- language with dynamic semantics. Its high-level built in data
- structures, combined with dynamic typing and dynamic binding, make it
- very attractive for rapid application development, as well as for use
- as a scripting or glue language to connect existing components
- together. Python's simple, easy to learn syntax emphasizes
- readability and therefore reduces the cost of program maintenance.
- Python supports modules and packages, which encourages program
- modularity and code reuse. The Python interpreter and the extensive
- standard library are available in source or binary form without charge
- for all major platforms, and can be freely distributed.
-
- Often, programmers fall in love with Python because of the increased
- productivity it provides. Since there is no compilation step, the
- edit-test-debug cycle is incredibly fast. Debugging Python programs is
- easy: a bug or bad input will never cause a segmentation fault.
- Instead, when the interpreter discovers an error, it raises an
- exception. When the program doesn't catch the exception, the
- interpreter prints a stack trace. A source level debugger allows
- inspection of local and global variables, evaluation of arbitrary
- expressions, setting breakpoints, stepping through the code a line at
- a time, and so on. The debugger is written in Python itself,
- testifying to Python's introspective power. On the other hand, often
- the quickest way to debug a program is to add a few print statements
- to the source: the fast edit-test-debug cycle makes this simple
- approach very effective.
