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')
