Question

我正在关注此主题的回复：Python: parsing structured text to CSV format我在导出数据时遇到困难。我对原始主题中最佳投票结果提出的脚本做了一些修改，但我只能将最后一组结果放到CSV文件中，没有其他内容写入。

原文是：

def read_records(iterable):
    record = {}
    for line in iterable:
        if line.isalnum():
            # Nuevo registro, mantiene anterior
            if record:
                yield record
            record = {}
            continue
        key, value = line.strip().split(":",1)
        record[key.strip()] = value.strip()

    # Archivo listo
    if record:
        yield record


# Salida encabezados
headers = ("Device ID", "SysName", "Entry address(es)", "IPv4 address", "Platform", "Interface", "Port ID (outgoing port)", "Holdtime")

with open("inputFile.txt") as infile, open("outputFile.csv", 'wb') as outfile:
    records = read_records(infile)
    writer = csv.DictWriter(outfile, headers, delimiter=';')
    writer.writeheader()

    # and write
    writer.writerows(records)

带有少量mod的代码是：


  <script src="assets/js/bootstrap.min.js"></script>

我真的被卡住了，我不知道为什么脚本只会写最后一组数据。拜托，请有人帮帮我吗？

提前致谢。

用于分隔记录的条件不太正确，请尝试：

def read_records(iterable):
    record = {}
    for line in iterable:
        if line.startswith('Device'):
            if record:
                yield record
            record = {}
        key, value = line.strip().split(":",1)
        record[key.strip()] = value.strip()
    if record:
        yield record

使用Python将纯文本文件解析为CSV
