Indentation is wrong on web-site,so have to fix that.
Here also a fix so it work Python 3.6 -->.
def main(filename):
    file = open(filename)  # oops, forgot the 'w'
    try:        
        try:
            compute()
        except Exception as exc:
            log(file, exc)
    finally:
        file.clos()   # oops, misspelled 'close'

def compute():
    1/0

def log(file, exc):
    try:
        print >>file, exc # oops, file is not writable
    except:
        display(exc)

def display(exc):
    print(ex)   # oops, misspelled 'exc'

main('result.csv')
Output:
