我有 csv 文件，如下所示。我想删除一行值之前的所有行 [Station Mac、第一次看到、上次看到、电源、数据包、BSSID、探测的 ESSID] 以进行进一步处理。我正在 python 中使用 panadad 库来读取此 csv 文件。我可以按索引删除特定行，但我的文件在 fes 秒后重新加载，行索引可以更改。我该怎么做呢。 我们将不胜感激您的帮助。

最佳答案
我们可以读取该文件，然后将其拆分到带有 2 个字符串的列表 s 中，一个包含空行之前的所有内容(使用 \n\n 作为分隔符)，另一个包含空行之后的所有内容。完成后，我们可以将这些字符串作为 CSV 读取到单独的 DataFrame 中:
with open('test.csv') as f:
s = f.read().split('\n\n')
df1 = pd.read_csv(pd.compat.StringIO(s[0]))
df2 = pd.read_csv(pd.compat.StringIO(s[1]))
df1:
BSSID First time seen Last time seen channel \
