如何按照官方文档正确进行文件安装？
我从传感器获取数据.有些时候他们blank string无缘无故地回到我身边!
在数据清理期间.我可以设法NaN使用它来获取列
df[df.isnull().values.any(axis=1)]
Time IL1 IL2 IL3 IN kVA kW kWh
12463 2018-09-17 10:30:00 63.7 78.4 53.3 25.2 NaN NaN 2039676.0
12464 2018-09-17 11:00:00 64.1 78.6 53.5 25.4 NaN NaN 2039698.0
我怎么能kVA and kW离开DataFrame？
然后,我能找到median的kVA and KW与其他行并更换NaN它
我的用例:
现在我必须读取文件并找到NaN列的位置.这需要我的努力.所以我想通过替换列名上的硬编码来自动化该过程.
trdb_a2_2018_df = pd.read_csv(PATH + 'dpm_trdb_a2_2018.csv', thousands=',', parse_dates=['Time'], date_parser=extract_dt)
trdb_a2_2018_df = trdb_a2_2018_df.replace(r'\s+', np.nan, regex=True)
median_kVA = trdb_a2_2018_df['kVA'].median()
trdb_a2_2018_df = trdb_a2_2018_df['kVA'].fillna(median_kVA)
