我创建了一个每小时日期数据框，现在我想创建一个列来标记每行（小时）是否处于夏令时。例如，在夏季，该标志应 == 1，而在冬季，该标志应 == 0。

# Localized dates dataframe
dates = pd.DataFrame(data=pd.date_range('2018-1-1', '2019-1-1', freq='h', tz='America/Denver'), columns=['date_time'])

# My failed attempt to create the flag column
dates['dst_flag'] = np.where(dates['date_time'].dt.daylight_saving_time == True, 1, 0)

我想将日期时间序列转换为季节,例如3个月,4个月,5个月我想用2(春天)替换它们; 几个月6,7,8我想用3(夏天)等替换它们.

所以,我有这个系列

id
1       2011-08-20
2       2011-08-23
3       2011-08-27
4       2011-09-01
5       2011-09-05
6       2011-09-06
7       2011-09-08
8       2011-09-09
Name: timestamp, dtype: datetime64[ns]

这是我一直试图使用的代码,但无济于事.

# Get seasons
spring = range(3, 5)
summer = range(6, 8)
fall = range(9, 11)
# winter = everything else

month = temp2.dt.month
season=[]

for _ in range(len(month)):
    if any(x == spring for x in month):
       season.append(2) # spring 
    elif any(x == summer for x in month):
        season.append(3) # summer
    elif any(x == fall for …
