I'm puzzled as to why you find this result confusing.  You're getting a
list of files, and putting their names (as strings) into a variable. 
You're then stripping the spaces from that variable and printing it. 
That doesn't have any effect on the file, because you're manipulating a
string containing the file_name_, not the file itself.  If you want to
rename the file, you need to do something like

	oldFilename = ...
	newFilename = oldFilename.strip()
	os.rename(oldFilename, newFilename)
