I usually don't do that, because it invalidates any filename arguments the  
program may have.
Instead, I use an explicit directory when I want it. For example, to open  
a .dat file located in the same directory as the module using it:

# top of the module
dat_path = os.path.dirname(os.path.abspath(__file__))

# when opening the file
f = open(os.path.join(dat_path, "filename.dat"))
