PeriodIndex 개체에서 기간의 월 번호를 가져오려면 PeriodIndex.month를 사용하세요. 재산.
먼저 필요한 라이브러리를 가져옵니다 -
import pandas as pd
PeriodIndex 객체 생성 -
periodIndex = pd.PeriodIndex(['2021-09-25 07:30:35', '2019-10-30 04:15:45', '2021-07-15 02:55:15', '2022-06-25 09:40:55'], freq="T")
PeriodIndex 빈도 표시 -
print("\nPeriodIndex frequency object...\n", periodIndex.freq)
PeriodIndex 개체의 월 번호를 표시합니다. 1월=1, 2월=2 ... 12월=12 −
로 표시된 월 IDprint("\nThe month number from the PeriodIndex object...\n", periodIndex.month)
예시
다음은 코드입니다 -
import pandas as pd # Create a PeriodIndex object # PeriodIndex is an immutable ndarray holding ordinal values indicating regular periods in time # We have set the frequency using the "freq" parameter periodIndex = pd.PeriodIndex(['2021-09-25 07:30:35', '2019-10-30 04:15:45', '2021-07-15 02:55:15', '2022-06-25 09:40:55'], freq="T") # Display PeriodIndex object print("PeriodIndex...\n", periodIndex) # Display PeriodIndex frequency print("\nPeriodIndex frequency object...\n", periodIndex.freq) # Display PeriodIndex frequency as string print("\nPeriodIndex frequency object as a string...\n", periodIndex.freqstr) # Display month number from the PeriodIndex object # The month id displayed as January=1, February=2 ... December=12. print("\nThe month number from the PeriodIndex object...\n", periodIndex.month)
출력
이것은 다음 코드를 생성합니다 -
PeriodIndex... PeriodIndex(['2021-09-25 07:30', '2019-10-30 04:15', '2021-07-15 02:55', '2022-06-25 09:40'], dtype='period[T]') PeriodIndex frequency object... <Minute> PeriodIndex frequency object as a string... T The month number from the PeriodIndex object... Int64Index([9, 10, 7, 6], dtype='int64')
