Python Pandas - PeriodIndex 객체에서 기간의 주 가져오기

PeriodIndex 개체에서 기간의 주를 가져오려면 PeriodIndex.week를 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 개체 표시 -

print("PeriodIndex...\n", periodIndex)

PeriodIndex 개체의 주 표시 -

print("\nThe week from the PeriodIndex object...\n", periodIndex.week)

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 week from the PeriodIndex object
print("\nThe week from the PeriodIndex object...\n", periodIndex.week)

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 week from the PeriodIndex object...
Int64Index([38, 44, 28, 25], dtype='int64')
