Still sorta a newbie myself, but here's my take.

in=open('C:\\foo.txt','r').readlines() 
#Opens the input file and reads each line into a list entry
out=open('C:\\bar.txt','w')
#Open output file
for x in in[:]:
#Loop once for every line
	if len(x)>1:
	#Test to see if the line has anything....
		out.write(x)
		#It does! Write it!

#Done!
(5 lines of active code that gets the job done!)
