我构建了这个数据帧:
import pandas as pd
from pandas.compat import StringIO
temp = '''A,B
A,23:59:32.897000
B,17:36:09.182000
C,21:56:57.325000
D,06:16:24.482000'''
df = pd.read_csv(StringIO(temp))
df['B'] = pd.to_datetime(df['B']).dt.time
所以我想知道是否有可能在30分钟的时间间隔内缩小输出时间:
A,B
A,23:30:00.000000
B,17:30:00.000000
C,21:30:00.000000
D,06:00:00.000000
任何帮助表示赞赏.
