python equivalent of bash find

[BartlebyScrivener]

I recently moved from XP to Linux, but would like to use Python
whenever possible.

line from bash script:

find ~/Mail -xdev -type f \( -mtime 0 -or -mtime 1 \) -exec cp -aPvu
"{}" /backup-dest \;

What modules would I use to accomplish this in Python? Or any other
Python tricks to copy or backup all files modified today?

Thank you,
