可以使用Python的`sorted()`函数来对列表进行排序,同时结合lambda表达式指定排序规则。具体如下:
```
sorted_list = sorted(list_, key=lambda x: x["score"] if isinstance(x["score"], int) else -1, reverse=True)
```
其中,`key`参数指定了排序规则,使用lambda表达式对每个字典元素的"score"字段进行判断,如果是整数则使用该值进行排序,否则将其排在最后(即分数为""或其他非整数类型)。`reverse`参数指定了是否倒序排序,这里设置为True表示按降序排列。排序后的结果将保存在`sorted_list`变量中。

if __name__ == '__main__':
This line of code is often used in Python scripts and modules to determine if the code is being run as the main program or if it is being imported as a module into another program.
When a Python file is imported as a module into another program, any code outside of a function or class definition will be executed. This can cause issues if the code is not intended to be run when the file is imported.
By using the if __name__ == '__main__': statement, code can be placed inside this block that will only execute if the file is being run as the main program. This allows for separation of code that is meant to be run as a standalone program versus code that is meant to be used as a module.
For example:
```
def my_function():
print('Hello, world!')
if __name__ == '__main__':
my_function()
```
In this example, the function `my_function()` is defined outside of the if statement. However, when the code is run, the function will only be called if the file is being run as the main program. If the file is imported as a module, the function will not be called.
list_ = [ {'execute_stage': {'name': '目标制定'}, "score": None}, {'execute_stage': {'name': 'asdasd'}, "score": None}, {'execute_stage': {'name': '多人评估'}, 'score': 45.0}, {'execute_stage': {'name': '多人评估'}, 'score': 43.0}, {'execute_stage': {'name': '多人评估'}, 'score': 47.0}, {'execute_stage': {'name': '多人评估'}, 'score': 0.0}, {'execute_stage': {'name': '结果计算'}, 'score': None}, {'execute_stage': {'name': '定案'}, 'score': None} ] 这段代码将 多人评估前面的字段和后面的字典和中间的多人评估分成三个部分
你可以使用循环来遍历列表中的每个字典,然后根据字典中的键值对来分割列表。下面是一个示例代码:
```python
evaluations = []
before_evaluations = []
after_evaluations = []
for item in list_:
if 'execute_stage' in item and item['execute_stage']['name'] == '多人评估':
evaluations.append(item)
elif len(evaluations) == 0:
before_evaluations.append(item)
else:
after_evaluations.append(item)
print(before_evaluations)
print(evaluations)
print(after_evaluations)
```
上述代码中,我们首先定义了三个空列表,分别用于存储多人评估前面的字段、多人评估和多人评估后面的字典。然后我们使用一个循环遍历列表中的每个字典项,判断该项是否为多人评估。如果是多人评估,则将该项添加到评估列表中;否则,如果评估列表为空,则将该项添加到多人评估前面的列表中;否则,将该项添加到多人评估后面的列表中。最后,我们打印出三个列表,以验证分割的结果是否正确。
