将列表中缺少的元素作为每个时间窗口组的行数插入到DataFrame

import pandas as pd
import numpy as np

df = pd.DataFrame({'time': ['2022-01-01 00:00:00', '2022-01-01 00:01:00', '2022-01-01 00:03:00'],
                   'value': [1, 2, 3]})
window_size = pd.Timedelta(minutes=2)

df['time'] = pd.to_datetime(df['time'])
df.set_index('time', inplace=True)

index = pd.date_range(start=df.index.min(), end=df.index.max(), freq=window_size)
df = df.reindex(index)

df['value'].fillna(0, inplace=True)
