If the standard Python library is not enough for you, a visit to the official Python web site will reveal a wealth of possibilities and bags of useful code which you can use to learn and solve your programming problems.
Hi MK- When I open Notepad, paste your line in there and save it and try to run it through windows scheduler, the commandline window opens for a split second and then closes. The goal of the course is to introduce students to Python Version 3.x programming using hands on instruction.
It will show how to install Python and use the Spyder IDE (Integrated Development Environment) for writing and debugging programs. Is there a tool to help find bugs or perform static analysis? ¶ Yes.
