[英]Append a dict in a nested dict python
I would like to have a dictionary appended with new dictionaries.我想要一本附有新词典的词典。
t = {}
t['bush_mod']={} # Toplevel
ana1 = {}
ana1['ana1_lin_001']={}
t['bush_mod'] = ana1 # Add below Toplevel
ana2 = {}
ana2['ana2_lin_001'] = {}
ana2['ana2_lin_002'] = {}
t['bush_mod'] = ana2 # Add below Toplevel
When I add ana2
the dictionary t
gets overwritten which i do not want.当我添加
ana2
,字典t
被我不想要的覆盖。
OUT: {'bush_mod': {'ana2_lin_001': {}, 'ana2_lin_002': {}}}
I wanted to have ana2
as the second dict (appended) below the Toplevel.我想让
ana2
作为ana2
下面的第二个字典(附加)。
OUT: {'bush_mod': {'ana1_lin_001': {}},{'ana2_lin_001': {}, 'ana2_lin_002': {}}}
It would really be helpful if someone could help me with the syntax.如果有人可以帮助我解决语法问题,那真的会很有帮助。
Thanks in advance!提前致谢!
If you want to stick to nested dictionaries I think dict.update
might be an option:如果你想坚持使用嵌套字典,我认为
dict.update
可能是一个选择:
t = {}
t['bush_mod']={}
ana1 = {}
ana1['ana1_lin_001']={}
ana2 = {}
ana2['ana2_lin_001'] = {}
ana2['ana2_lin_002'] = {}
t['bush_mod'].update(ana1)
t['bush_mod'].update(ana2)
Such that t
is:这样
t
是:
{'bush_mod': {'ana1_lin_001': {}, 'ana2_lin_001': {}, 'ana2_lin_002': {}}}
dict.update
here adds the keys-value pairs from ana1
and ana2
to the dictionary t['bush_mod
]` dict.update
在这里将ana1
和ana2
的键值对ana2
到字典t['bush_mod
]`
you need to use distinct keys for each element in the dict t... it is overriding because you used 'bush_mod' twice...您需要为 dict t 中的每个元素使用不同的键...它是覆盖的,因为您使用了 'bush_mod' 两次...
you need to make t['bush_mod']= [] then append that list with things.您需要使 t['bush_mod']= [] 然后在该列表中附加一些东西。
t['bush_mod'] = []
t['bush_mod'].append(ana1)
t['bush_mod'].append(ana2)
