从Python

Question

我想从这一栏中提取出“A”。在这之后，我希望能够从同一行中与“A”相关联的其他列打印其他数据。 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。 这是我的代码如下： 先谢谢

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))
