在 Python 中从数据框中的列中提取数据

Question

我想从该列中提取“A”。之后，我希望能够在同一行中打印与“A”关联的其他列中的其他数据。 但是，我的代码打印了这个：

outputs:
UniqueCarrier       NaN
CancellationCode    NaN
Name: CancellationCode, dtype: object
None

CancellationCode 列如下所示：

  CancellationCode:
        NaN
         A
        NaN
         B
        NaN

我想让它以带有过滤的行和列的数据框格式打印。

下面是我的代码：

cancellation_reason = (flight_data_finalcopy["CancellationCode"] == "A")
cancellation_reasons_filtered = cancellation_reason[["UniqueCarrier", "AirlineID", "Origin"]]
print(display(cancellation_reasons_filtered))

Answer 1

试试这个

cancellation_reason=flight_data_finalcopy[flight_data_finalcopy["CancellationCode"] == "A"]
cancellation_reasons_filtered = cancellation_reason[["UniqueCarrier", "AirlineID", "Origin"]]
print(display(cancellation_reasons_filtered))
