[python] najdi, nahrad, uloz v ascii subore

[Leos Pol]

Ahoj,
omlouvam se, ale nedokazal jsem tvuj kod opravit, tak posilam alespon 
svoje reseni:

    import re
    fd = open('data.txt', 'r+')
    content = fd.read()
    delimiter = re.search('\$-+', content).group()
    blocks = re.split('\$-+', content)
    for idx in range(len(blocks)):
        if 'NAME=\'ALFA\'' in blocks[idx]:
            code = re.search('CODE=\'(.*)\'', blocks[idx]).groups()
            blocks[idx] = blocks[idx].replace('NAME=\'ALFA\'',
    'NAME=\'BETA%s\'' % code)
    fd.seek(0)
    fd.write(delimiter.join(blocks))
    fd.close()

Doufam, ze to pomuze,
Leo
PS: nejspise ale asi hledas "seek" a "tell".
