Newby Question: Remove files older than 7 days from a directory

[kbass]

I would like to remove file that are older than 7 days old from a directory.
I can do this in shell script rather easy but I would like to integrate this
functionality into my Python program. How can this be achieved? Which module
can be used to perform this tasks? Thanks!

Shell Script example:   find /path/to/dir -mtime +30 -exec rm '{}' \;
