Re: regex to remove lines made of only whitespace

text = ''.join(strip_blank_lines(lines.split('\n')))

The final version I have is:

def strip_blank_lines(text):
    result = []
    for line in text.split('\n'):
        if line and not line.isspace():
            result.append(line)
    return '\n'.join(result)

Any improvements would be very welcome!
