这个错误提示表明你提供的OpenWeatherMap API Key无效。请检查你的API Key是否正确并且有效。你可以在OpenWeatherMap的官方网站上登录账户并获取新的API Key。
同时,你的代码中需要在导入pyowm模块之前添加OpenWeatherMap的API Key,将代码修改如下:
```python
import datetime
import pyowm
# 获取当前时间
now = datetime.datetime.now()
# 获取上个月的时间
last_month = now.replace(month=now.month-1)
# 初始化OpenWeatherMap对象
owm = pyowm.OWM('your-api-key') # 把'your-api-key'替换成你的API Key
# 获取上个月的天气情况
mgr = owm.weather_manager()
observation = mgr.weather_at_place('上海')
```
请注意,你需要将代码中的 `'your-api-key'` 替换成你在OpenWeatherMap官网上申请的API Key。另外,你需要安装pyowm模块,可以使用pip命令进行安装,命令如下:
```
pip install pyowm
```

import pyowm import datetime # 获取当前时间 now = datetime.datetime.now() # 获取上个月的时间 last_month = now.replace(month=now.month-1) # 初始化OpenWeatherMap对象 owm = pyowm.OWM('cff205d4bc569aaffdb80114250e52df') # 把'your-api-key'替换成你的API Key # 获取上个月的天气情况 mgr = owm.weather_manager() observation = mgr.weather_at_place('Shanghai') date_obj = datetime.datetime(last_month.year, last_month.month, 1) one_call = mgr.one_call(lat=observation.weather.location.lat, lon=observation.weather.location.lon, dt=date_obj.timestamp(), exclude='current,minutely,hourly,alerts') condition = one_call.forecast_daily[0].status print('上个月的天气情况是:', condition)被返回'Weather' object has no attribute 'location'
根据您提供的代码,问题可能出在以下这行代码:
```
observation = mgr.weather_at_place('Shanghai')
```
在这里,`observation`对象是通过`mgr.weather_at_place()`方法获取的,但是您并没有指定获取的是哪个时间段的天气数据。因此,`observation`对象只包含当前的天气数据,而没有日期信息。在下一行代码中,您又试图从`observation.weather.location`中获取经纬度信息,因此会出现`'Weather' object has no attribute 'location'`的错误。
要解决这个问题,您可以考虑修改`weather_at_place()`方法的参数,指定获取某个时间点的天气数据。例如,您可以使用`mgr.weather_at_place('Shanghai, CN', time=date_obj.timestamp())`获取上个月的天气数据,其中`'Shanghai, CN'`是城市名称和国家代码的组合,`date_obj.timestamp()`是上个月第一天的时间戳。
修改后的代码如下:
```
import pyowm
import datetime
# 获取当前时间
now = datetime.datetime.now()
# 获取上个月的时间
last_month = now.replace(month=now.month-1)
# 初始化OpenWeatherMap对象
owm = pyowm.OWM('your-api-key') # 把'your-api-key'替换成你的API Key
# 获取上个月的天气情况
mgr = owm.weather_manager()
observation = mgr.weather_at_place('Shanghai, CN', time=date_obj.timestamp()) # 修改这里的参数
condition = observation.weather.status
print('上个月的天气情况是:', condition)
```
请注意,这只是一个示例代码,可能还需要根据您的实际需求进行修改和完善。

这是一个Java GUI程序,是一个日历软件,实现了对日历的显示和时间的实时更新。用户可以选择日期,程序会弹出对话框,显示用户选择的日期。程序的界面比较简单,分为三个面板,p1面板上放置了输入年月和确认按钮,p2面板上放置了星期几,p3面板上放置了日期。程序主要是通过Calendar类和JButton、JLabel等Swing组件实现的。
