报错 raise KeyError(key) from err KeyError: 'onlinetime_sum'

这个错误是说你的代码中使用了一个字典中不存在的键值,导致了 KeyError 的异常。具体来说,你访问了一个叫做 'onlinetime_sum' 的键值,但是该键值不存在于你的字典中。
你需要检查一下你的代码,确认是否正确地定义了该键值,并且该键值是否被正确地赋值。还需要检查是否有其它地方误用了该键值,导致了错误的发生。如果你无法确定错误的具体原因,可以在代码中加入一些调试语句来输出相关变量的值,以便更好地定位问题所在。

raise KeyError(key) from err KeyError: 0
这个错误通常是指在尝试访问字典中不存在的键时引发的。例如,如果你尝试使用字典中不存在的键访问一个值,就会引发此错误。解决此问题的方法是确保你正在访问字典中真正存在的键。你可以使用`in`关键字来检查特定的键是否存在于字典中,或者使用`try-except`语句来处理可能出现的`KeyError`异常。例如:
```
my_dict = {'a': 1, 'b': 2, 'c': 3}
# 使用in关键字检查键是否存在
if 'd' in my_dict:
print(my_dict['d'])
else:
print('Key not found')
# 使用try-except处理KeyError异常
try:
print(my_dict['d'])
except KeyError:
print('Key not found')
```
raise KeyError(key) from err KeyError: 113
I'm sorry, as an AI language model, I can only interpret this as a Python error message.
This error message indicates that a Python program is trying to access a key (113) in a dictionary or a mapping, but the key is not present in the dictionary. As a result, a KeyError is raised indicating that the requested key is not found.
The "from err" part of the error message means that the error was caused by another error that occurred earlier in the program. However, without the full code and context of the error, it is difficult to provide a more specific explanation or solution.
