法律研究Python Pandas - 使用 DateTimeIndex 创建时间戳
若要创建时间戳，我们将使用 date_range()。周期和时区也将使用频率进行设置。首先，导入所需的库 −
import pandas as pd
时期为 8、频率为 M 即将月的时间戳索引。时区为澳大利亚/悉尼 −
datetime = pd.date_range('2021-09-24 02:35:55', periods=8, tz='Australia/Sydney', freq='M')
显示时间戳 −
print("DateTime...\n", datetime)示例
以下是代码 −
import pandas as pd
# DatetimeIndex with period 8 and frequency as M i.e. months
# timezone is Australia/Sydney
datetime = pd.date_range('2021-09-24 02:35:55', periods=8, tz='Australia/Sydney', freq='M')
# display
print("DateTime...\n", datetime)
# get the day name
print("\nGetting the day name..\n",datetime.day_name())
# get the month name
print("\nGetting the month name..\n",datetime.month_name())
# get the year
print("\nGetting the year name..\n",datetime.year)
# get the hour
print("\nGetting the hour..\n",datetime.hour)
# get the minutes
print("\nGetting the minutes..\n",datetime.minute)
# get the seconds
print("\nGetting the seconds..\n",datetime.second)输出
将生成以下输出 −
DateTime... 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', '2022-03-31 02:35:55+11:00', '2022-04-30 02:35:55+10:00'], dtype='datetime64[ns, Australia/Sydney]', freq='M') Getting the day name.. Index(['Thursday', 'Sunday', 'Tuesday', 'Friday', 'Monday', 'Monday','Thursday', 'Saturday'], dtype='object') Getting the month name.. Index(['September', 'October', 'November', 'December', 'January', 'February','March', 'April'], dtype='object') Getting the year name.. Int64Index([2021, 2021, 2021, 2021, 2022, 2022, 2022, 2022], dtype='int64') Getting the hour.. Int64Index([2, 2, 2, 2, 2, 2, 2, 2], dtype='int64') Getting the minutes.. Int64Index([35, 35, 35, 35, 35, 35, 35, 35], dtype='int64') Getting the seconds.. Int64Index([55, 55, 55, 55, 55, 55, 55, 55], dtype='int64')
