Question

我正在从JSON文件中读取数据，并且我尝试根据键（导演+ sprintname）附加三个计算总体saydo，已提交的saydo和额外的saydo。我收到下面的错误。 TypeError：append（）仅接受一个参数（给定2个参数）

代码：

import json


with open('C:/Users/erpsaam/Desktop/report-v89/kpi-report-aggregation-by- 
director-2018-08-31.json') as f:
category_director_json = json.load(f)


category_director_dataset = []  # we will fill this in this script
for row in category_director_json:
row.get('director',None)
row.get('sprintName', None)
row.get('overallSayDo', None)
row.get('commitedSayDo', None)
row.get('extraSayDo', None)
category_director_dataset.append("DIRECTOR+SPRINTNAME", {'overallSayDo': 'overallSayDo_value', 'commitedSayDo': 'commitedSayDo_value', 'extraSayDo': 'extraSayDo_value'})
print(json.dumps(category_director_dataset))

我该如何修正append语句？

Answer 1

是的，很明显，就像我们从错误中看到的那样。只需将其更改为：

category_director_dataset.append("DIRECTOR+SPRINTNAME")
category_director_dataset.append({'overallSayDo': 'overallSayDo_value', 
'commitedSayDo': 'commitedSayDo_value', 'extraSayDo': 'extraSayDo_value'})

Answer 2

错误

可以在以下行中找到错误：

category_director_dataset.append("DIRECTOR+SPRINTNAME", {'overallSayDo': 'overallSayDo_value', 'commitedSayDo': 'commitedSayDo_value', 'extraSayDo': 'extraSayDo_value'})
                                                      ^
                                                      ^ error is this comma here

基本上可以简化为：

a_list.append(value1, value2)

仔细阅读错误消息：

TypeError：append（）仅接受一个参数（给定2个参数）

append(x)方法仅接受一个参数，但您已经在其中添加了两个参数。

您可以做什么

将您的参数放入一个元组（用括号括起来）以将参数数量减少为一个
使用其他数据结构（也许字典对您的情况有用，因为您已经提到过要使用DIRECTOR+SPRINTNAME作为键？）

带有字典

DIRECTOR = "director"
SPRINTNAME = "sprint"
category_director_dataset = {}
category_director_dataset[DIRECTOR + SPRINTNAME] = { ... your data here ... }

因此，如果您要检索给定DIRECTOR + SPRINTNAME的JSON，只需执行以下操作：

json = category_director_dataset[DIRECTOR + SPRINTNAME]
