我是 Python 新手..

我可以通过将两个字典与dictdiffer 进行比较来生成以下输出，它位于oo 变量中：

oo = ('remove', '', [('we are here to help you improve your skills', [['2021-04-09', 'email@example.com', 'we are here to help you improve your skills', 'Delivered']]), ('(1st meeting) here is our recorded presentation skills webinar', [['2021-04-12', 'email@example.com', '(1st meeting) here is our recorded presentation skills webinar', 'Delivered']]), ('YOU ARE INVITED TO THIS PROGRAMMING EVENT', [['2021-04-13', 'email@example.com', 'YOU ARE INVITED TO THIS PROGRAMMING EVENT', 'Delivered'], ['2021-04-16', 'email@example.com', 'YOU ARE INVITED TO THIS PROGRAMMING EVENT', 'Delivered']])])
('remove', '', [('we are here to help you improve your skills', [['2021-04-09', 'email@example.com', 'we are here to help you improve your skills', 'Delivered']]), ('(1st meeting) here is our recorded presentation skills webinar', [['2021-04-12', 'email@example.com', '(1st meeting) here is our recorded presentation skills webinar', 'Delivered']]), ('YOU ARE INVITED TO THIS PROGRAMMING EVENT', [['2021-04-13', 'email@example.com', 'YOU ARE INVITED TO THIS PROGRAMMING EVENT', 'Delivered'], ['2021-04-16', 'email@example.com', 'YOU ARE INVITED TO THIS PROGRAMMING EVENT', 'Delivered']])])
('remove', '', [('we are here to help you improve your skills', [['2021-04-09', 'email@example.com', 'we are here to help you improve your skills', 'Delivered']]), ('(1st meeting) here is our recorded presentation skills webinar', [['2021-04-12', 'email@example.com', '(1st meeting) here is our recorded presentation skills webinar', 'Delivered']]), ('YOU ARE INVITED TO THIS PROGRAMMING EVENT', [['2021-04-13', 'email@example.com', 'YOU ARE INVITED TO THIS PROGRAMMING EVENT', 'Delivered'], ['2021-04-16', 'email@example.com', 'YOU ARE INVITED TO THIS PROGRAMMING EVENT', 'Delivered']])])

我想访问 此元组中的列表，输出如下：

['2021-04-09', 'email@example.com', 'we are here to help you improve your skills', 'Delivered']
['2021-04-12', 'email@example.com', '(1st meeting) here is our recorded presentation skills webinar', 'Delivered']
['2021-04-13', 'email@example.com', 'YOU ARE INVITED TO THIS PROGRAMMING EVENT', 'Delivered']
 ......
 ......

到目前为止我所做的只是looping by index value：

for tuple in enumerate(oo):
    for list in tuple[1]:
        for activity in list:
            print(activity[0])

但是输出是随机字母，并不是每个列表（以日期开头）都在那里！：

r
e
m
o
v
e
w
['2021-04-09', 'email@example.com', 'we are here to help you improve your skills', 'Delivered']
(
['2021-04-12', 'email@example.com', '(1st meeting) here is our recorded presentation skills webinar', 'Delivered']
Y
['2021-04-13', 'email@example.com', 'YOU ARE INVITED TO THIS PROGRAMMING EVENT', 'Delivered']

如何排列列表并从这个多元组变量中检索它们？

数据结构似乎是元组和列表的元组。

以下似乎可以达到预期的效果。


oo = ('remove', '', [('we are here to help you improve your skills', [['2021-04-09', 'email@example.com', 'we are here to help you improve your skills', 'Delivered']]), ('(1st meeting) here is our recorded presentation skills webinar', [['2021-04-12', 'email@example.com', '(1st meeting) here is our recorded presentation skills webinar', 'Delivered']]), ('YOU ARE INVITED TO THIS PROGRAMMING EVENT', [['2021-04-13', 'email@example.com', 'YOU ARE INVITED TO THIS PROGRAMMING EVENT', 'Delivered'], ['2021-04-16', 'email@example.com', 'YOU ARE INVITED TO THIS PROGRAMMING EVENT', 'Delivered']])])
('remove', '', [('we are here to help you improve your skills', [['2021-04-09', 'email@example.com', 'we are here to help you improve your skills', 'Delivered']]), ('(1st meeting) here is our recorded presentation skills webinar', [['2021-04-12', 'email@example.com', '(1st meeting) here is our recorded presentation skills webinar', 'Delivered']]), ('YOU ARE INVITED TO THIS PROGRAMMING EVENT', [['2021-04-13', 'email@example.com', 'YOU ARE INVITED TO THIS PROGRAMMING EVENT', 'Delivered'], ['2021-04-16', 'email@example.com', 'YOU ARE INVITED TO THIS PROGRAMMING EVENT', 'Delivered']])])
('remove', '', [('we are here to help you improve your skills', [['2021-04-09', 'email@example.com', 'we are here to help you improve your skills', 'Delivered']]), ('(1st meeting) here is our recorded presentation skills webinar', [['2021-04-12', 'email@example.com', '(1st meeting) here is our recorded presentation skills webinar', 'Delivered']]), ('YOU ARE INVITED TO THIS PROGRAMMING EVENT', [['2021-04-13', 'email@example.com', 'YOU ARE INVITED TO THIS PROGRAMMING EVENT', 'Delivered'], ['2021-04-16', 'email@example.com', 'YOU ARE INVITED TO THIS PROGRAMMING EVENT', 'Delivered']])])


for x in oo[2]:
    for y in x[1]: 
        print(y)

['2021-04-09', 'email@example.com', 'we are here to help you improve your skills', 'Delivered']
['2021-04-12', 'email@example.com', '(1st meeting) here is our recorded presentation skills webinar', 'Delivered']
['2021-04-13', 'email@example.com', 'YOU ARE INVITED TO THIS PROGRAMMING EVENT', 'Delivered']
['2021-04-16', 'email@example.com', 'YOU ARE INVITED TO THIS PROGRAMMING EVENT', 'Delivered']
