Python Pandas - PeriodIndex 객체에서 요일 가져오기

PeriodIndex 개체에서 요일을 가져오려면 PeriodIndex.weekday를 사용하세요. 재산.

먼저 필요한 라이브러리를 가져옵니다 -

import pandas as pd

PeriodIndex 개체를 만듭니다. PeriodIndex는 일정 기간을 나타내는 서수 값을 보유하는 변경할 수 없는 ndarray입니다. −

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 개체에서 요일을 표시합니다. 월요일=0, 화요일=1 ... 일요일=6 −

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

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)

# Display day of the week from the PeriodIndex object
# The day of the week with Monday=0, Tuesday=1 ... Sunday=6
print("\nThe day of week from the PeriodIndex object...\n", periodIndex.weekday)

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')

The day of week from the PeriodIndex object...
Int64Index([5, 2, 3, 5], dtype='int64')
