Adding data to a list by line

Hey guys,

Say I was using the subprocess module to print data listed in the command line of UNIX into python. For example:

File: FileName.jpg
FileSize: 1024
FileRes: 512×512

How would I add that data to a list by line? Or perhaps even better, how would I add that data to a list for everything after the colons. For example, I want that data to become:

[‘FileName.jpg’,’1024′,’512×512′]

I’m kind of new to programming, so the more description the better!

Thanks for any help in advance!
