Python Pandas - 从具有特定时间序列频率的 DateTimeIndex 中提取分钟
要从具有特定时间序列频率的 DateTimeIndex 中提取分钟,请使用 DateTimeIndex.minute 属性。
首先,导入所需的库 -
import pandas as pd
创建一个具有周期 6 和频率为 T,即 minute 的 DatetimeIndex。时区为澳大利亚/悉尼 -
datetimeindex = pd.date_range('2021-10-20 02:30:55', periods=6, tz='Australia/Sydney', freq='T')
显示 DateTimeIndex -
print("DateTimeIndex...\n", datetimeindex)
获取分钟 -
print("\nGetting the minute..\n",datetimeindex.minute)
范例
以下是代码 -
import pandas as pd # DatetimeIndex with period 6 and frequency as T i.e. minute # The timezone is Australia/Sydney datetimeindex = pd.date_range('2021-10-20 02:30:55', periods=6, tz='Australia/Sydney', freq='T') # display DateTimeIndex print("DateTimeIndex...\n", datetimeindex) # display DateTimeIndex frequency print("DateTimeIndex frequency...\n", datetimeindex.freq) # get the minute print("\nGetting the minute..\n",datetimeindex.minute)
输出
这将生成以下代码 -
DateTimeIndex... DatetimeIndex(['2021-10-20 02:30:55+11:00', '2021-10-20 02:31:55+11:00', '2021-10-20 02:32:55+11:00', '2021-10-20 02:33:55+11:00', '2021-10-20 02:34:55+11:00', '2021-10-20 02:35:55+11:00'], dtype='datetime64[ns, Australia/Sydney]', freq='T') DateTimeIndex frequency... <Minute> Getting the minute.. Int64Index([30, 31, 32, 33, 34, 35], dtype='int64')
