I wrote the below code

    def parseDirections(text):
        words = {'N': 'north', 'S': 'south', 'E': 'east', 'W': 'west'}
        output = [words[w] for w in list(text)]
        return '    '.join(output)
    acronyms = re.findall('\\b([NESW]+)\\b', text)
    for w in acronyms:
        text = text.replace(w, parseDirections(w))
    text = re.sub('(\\b\\d+)F(\\b)', '\\g<1>    Fahrenheit\\g<2>', text)
    text = re.sub('(\\b)mph(\\b)', '\\g<1>miles    per    hour\\g<2>', text)
    text = re.sub('(\\b)in\\.', '\\g<1>inches', text)
    return text
