with open('path/to/input') as infile, open('path/to/output', 'w') as outfile:
    writer = csv.writer(outfile, delimiter='\t')
    for line in csv.reader(infile, delimiter='\t'):
        vals = line[-1]
        headers = line[:-1]
        for val in vals.split(';'):
            writer.writeline(headers + [val])
