What are good ways to make my Python code run first time? [closed]

Answer 1

Python provides a debugger which allows you to step through your code, inspect variables and manipulate them. Refer to http://pythonconquerstheuniverse.wordpress.com/category/python-debugger/ which can take you over the steps...

Also check the python standard library reference for pdb http://www.python.org/doc/2.5.2/lib/module-pdb.html
