If there's not going to be any other whitespace at the end of the line 
that you might want to keep, the strip() or rstrip() string methods are 
useful:

 >>> s = "this is a string ending in a newline\n"
 >>> s
'this is a string ending in a newline\n'
 >>> s.strip()
'this is a string ending in a newline'
 >>> s2 = "no newline here!!"
 >>> s2.strip()
'no newline here!!'
 >>> s3 = "   this is a test   \n"
 >>> s3
'   this is a test   \n'
 >>> s3.strip()
'this is a test'
 >>> s3.rstrip()
'   this is a test'
 >>>
