我有一个字典,我想分成一个字典列表,用于将提交添加到数据库中
这是字典,这不是一个静态的dict,它是动态生成的,因此数字可以增加:
# notice the keys are all grouped by numbers,
data = {'resident_payer,1': 'William Brown',
'Term Fee,amount_paid,1': '1',
'method,1': 'credit',
'document_id,1': '1',
'resident_payer,2': None,
'Term Fee,amount_paid,2': '0',
'method,2': 'other',
'document_id,2': '0'}
我需要一个字典列表,如下所示:
[
{'resident_payer': 'William Brown', 'Term Fee,amount_paid': '1', 'method': 'credit', 'document_id': '1'},
{'resident_payer': None, 'Term Fee_amount_paid': '0', 'method': 'other', 'document_id': '0'}
]
我如何用听写理解的简单方法来做这件事
这里是工作代码,但我无法找出解决方案,因为我正在使用和清除循环外声明的变量,因此我希望使用一种更清晰的python方式来编写此代码
data = {'resident_payer,1': 'William Brown',
'Term Fee,amount_paid,1': '1',
'method,1': 'credit',
'document_id,1': '1',
'resident_payer,2': None,
'Term Fee,amount_paid,2': '0',
'method,2': 'other',
'document_id,2': '0'}
# will hold broken down lists
list_of_submissions = list()
# used to parse data into separated list of dictionaries.
# The key is split into numbers for grouping
current_loop = 1
active_dict_to_add_to_list = dict()
for key, value in data.items():
if f'{current_loop}' in key:
# we are in the current iteration
# add the item to the active dict, the key is split by the ',' and [1] is the number so [0] needs to be selected
# slice by 0: -1 to get first to everything but last element
key_to_use = ",".join(key.split(',')[0:-1])
active_dict_to_add_to_list[key_to_use] = value
print(active_dict_to_add_to_list)
# I know the dict should be 4 in length s I can realize I need to add here, but I don't like that...
if len(active_dict_to_add_to_list) == 4:
list_of_submissions.append(active_dict_to_add_to_list)
# print('added', active_dict_to_add_to_list)
active_dict_to_add_to_list = dict()
current_loop += 1
else:
# we need to move to new iteration
# add the current active dict to the list of submissions
list_of_submissions.append(active_dict_to_add_to_list)
print('added', active_dict_to_add_to_list)
# clear the active dict so it can be added again
active_dict_to_add_to_list = dict()
current_loop += 1
print(list_of_submissions)
您可以使用^{} :

这是我能合理减少的范围:

这是假设您希望输出列表按照用于对条目进行分组的数字(在中间字典
