Hi,
I was wondering if anyone knows the difference between .py and .pyw when making python applications? I am learning python and haven't found any real answer to this question. Thanks,

Its basically just a Python User Interface file. So a Python file that opens up a new Window without the command line.

pyw means run the script without invoking the console window, especially if your program is GUI based. If you rename the file to py extension,you still can run it.

Weird... ghostdog74 and maddog39...

Anyway, trying to stay on topic... I didn't know "pyw" existed until this post!

not weird though, from what i know, in Python for windows, .pyw script is called by pythonw.exe. (as opposed to python.exe)

Well this is true that .py file runs on console basis that is using command prompt or terminal and .pyw files are used when you are building a GUI application and not a console application using Qt or Jython and some other tools which help in Python GUI programming

It's also a nice feature for when you want a script to be continuously running in the background, but don't want an ugly console getting in the way or risking that the user accidentally exits the script.
