要将DateTimeIndex中的时间转换为午夜,请使用Pandas中的。DateTimeIndex.normalize()
首先,导入所需的库-
import pandas as pd创建一个日期时间索引,周期为7,频率为H即小时-
datetimeindex = pd.date_range(2021-10-30 02:30:50, periods=7, tz=Australia/Adelaide, freq=10H)显示日期时间索引-
print("DateTimeIndex...\n", datetimeindex)日期时间的时间部分转换为午夜,即00:00:00-
print("\nNormalize (converted the time component to midnight)...\n", datetimeindex.normalize())以下是代码-
import pandas as pd #DatetimeIndex周期为7,频率为H即小时 #时区是澳大利亚/阿德莱德 datetimeindex = pd.date_range(2021-10-30 02:30:50, periods=7, tz=Australia/Adelaide, freq=10H) #显示日期时间索引 print("DateTimeIndex...\n", datetimeindex) #显示日期时间索引 frequency print("\nDateTimeIndex frequency...\n", datetimeindex.freq) #日期时间的时间部分转换为午夜,即00:00:00 print("\nNormalize (converted the time component to midnight)...\n", datetimeindex.normalize())输出结果这将产生以下代码-
DateTimeIndex... DatetimeIndex([2021-10-30 02:30:50+10:30, 2021-10-30 12:30:50+10:30, 2021-10-30 22:30:50+10:30, 2021-10-31 08:30:50+10:30, 2021-10-31 18:30:50+10:30, 2021-11-01 04:30:50+10:30, 2021-11-01 14:30:50+10:30], dtype=datetime64[ns, Australia/Adelaide], freq=10H) DateTimeIndex frequency... <10 * Hours> Normalize (converted the time component to midnight)... DatetimeIndex([2021-10-30 00:00:00+10:30, 2021-10-30 00:00:00+10:30, 2021-10-30 00:00:00+10:30, 2021-10-31 00:00:00+10:30, 2021-10-31 00:00:00+10:30, 2021-11-01 00:00:00+10:30, 2021-11-01 00:00:00+10:30], dtype=datetime64[ns, Australia/Adelaide], freq=None)
