Python Pandas - 从带有特定时间序列频率的 DateTimeIndex 中提取月份
如要从带有特定时间序列频率的 DateTimeIndex 中提取月份,请使用 DateTimeIndex.month 属性。
首先,导入所需的库 −
import pandas as pd
DatetimeIndex 的周期为 6,频率为 M,即月份。时区为澳大利亚/悉尼 −
datetimeindex = pd.date_range('2021-09-24 02:35:55', periods=6, tz='Australia/Sydney',freq='M')显示 DateTimeIndex −
print("DateTimeIndex...\n", datetimeindex)获取月份,即 1 月=1,2 月=2,...,12 月=12 −
print("\nGetting the month number..\n",datetimeindex.month)
示例
以下是代码 −
import pandas as pd
# DatetimeIndex with period 6 and frequency as M i.e. month
# timezone is Australia/Sydney
datetimeindex = pd.date_range('2021-09-24 02:35:55', periods=6, tz='Australia/Sydney',freq='M')
# display DateTimeIndex
print("DateTimeIndex...\n", datetimeindex)
# display DateTimeIndex frequency
print("DateTimeIndex frequency...\n", datetimeindex.freq)
# get the month number i.e. January=1, february=2, ..., December=12
print("\nGetting the month number..\n",datetimeindex.month)输出
会生成以下输出 −
DateTimeIndex...
DatetimeIndex(['2021-09-30 02:35:55+10:00', '2021-10-31 02:35:55+11:00',
'2021-11-30 02:35:55+11:00', '2021-12-31 02:35:55+11:00',
'2022-01-31 02:35:55+11:00', '2022-02-28 02:35:55+11:00'],
dtype='datetime64[ns, Australia/Sydney]', freq='M')
DateTimeIndex frequency...
