[?] sorting files by modification time.

[Francisco Borges]

 Hello all,

  I want to list some files in a directory and sort them by the
  modification time.

 As far as I could tell, I can't do that with os.listdir and neither
 with glob, is this right?

I thought about
 >>> os.system('ls -t')

but it will thrown the output to stdout. Is there a simpler way to do
this than start messing with the stdout or with the shell??? 

 thank you for your attention,
