根据日期时间范围为pandas数据帧分配列值

您可以使用pd.Series.between方法,而不是pd.date_range和isin

这是一个例子

import pandas as pd

#dict
d = {'A': ['2020-01-01 00:00:00+00:00', '2024-01-24 00:00:00+00:00']}

# Let's convert strings to datetime
for k, (start, end) in d.items():
  d[k] = [pd.to_datetime(start), pd.to_datetime(end)]

#df
df = pd.DataFrame({
'ID': [1, 2, 3],
'time': pd.to_datetime(['2024-01-23 00:00:00+00:00', '2025-01-23 
 00:00:00+00:00', '2019-01-23 00:00:00+00:00'])
 })

# Assign labels
for k, (s, e) in d.items():
   df.loc[df["time"].between(s, e), 'Label'] = k

print(df)
