v2.4? Hmm, old. I think this is still valid tho'....

Look in the os.path module for a bunch of mode/access
test functions for common tests.

Or

os.access() takes a filename and flag variable (one of os.F_OK,
os.R_OK, os.W_OK, and os.X_OK) which returns a Boolean result depending 
on whether the file exists, is readable, writable or executable 
respectively.

Alternatively use os.stat() and treat the mode attribute
result as a bitmask using the stat flags
