Given a piece of Python code like this:

The CMD window pops up each time, despite me saving the file as a .pyw! Any help appreciated

I'm assuming Windows? Which version it doesn't for me on Windows 7. — Ben, Jun 07 '12 at 17:03
Windows creates a command window whenever you run a command-line process. Can't be helped. — Mark Ransom, Jun 07 '12 at 17:09

It's because you're running Python from a window that you get a pop-up console window. Console programs can only be run from a console, and if the program environment doesn't already include one Windows will helpfully create it.

os.system does open a command window by design. The subprocess module should let you do somethings without opening a window.

Also, for certain commands (say copy, delete) you could use specialized OS commands that won't open a command window and have the advantage of being more cross-OS.
