问题描述

你好,


我似乎无法找到一种方法来添加更多的键/值到最后

的字典......我怎么能这样做?


例如:


mydict = {'''':''1''}

我需要附加''b'':'''''它要有:


mydict = {''a'': ''1',''b'':''2''}


怎么办?


祝你好运,

Yves

你好,

例如:

mydict = {''a'':''1''}

我需要追加''b'':''2''它有:
mydict = {''a'':''1'','b'':''2''}



mydict [''b' '] =''2''

字典没有订单,因此没有结束。

mydict = {'''':''1''}

我需要附加''b'':'''''它要有:

mydict = {''a'':''1'',''b '':''2''}

怎么办?




喜欢这个:

mydict = {'''':''1''} mydict [''b''] ='''2' '
打印mydict
{''a'':''1'','b'':''2''} {'''''''''''' 'b'':''2''} == {''b'':''2'',''''''''1''}

字典没有结束,因为它是一个无序的

集合。

例如:
mydict = {''a'':''1''}
我需要追加''b'':'''''它有:




mydict [''b''] =''2''

打印mydict

Hi there,

I seem to be unable to find a way to appends more keys/values to the end
of a dictionary... how can I do that?

E.g:

mydict = {''a'':''1''}

I need to append ''b'':''2'' to it to have:

mydict = {''a'':''1'',''b'':''2''}

How to do?

Best regards,
Yves

A dictionary has no order, and therefore no end.
mydict = {''a'':''1''}

I need to append ''b'':''2'' to it to have:

mydict = {''a'':''1'',''b'':''2''}

How to do?



Like this:

mydict = {''a'':''1''}
mydict[''b''] = ''2''
print mydict {''a'': ''1'', ''b'': ''2''} {''a'': ''1'', ''b'': ''2''} == {''b'': ''2'', ''a'': ''1''}


True

A dictionary doesn''t have an ''end'' because it is an unordered
collection.
E.g:
mydict = {''a'':''1''}
I need to append ''b'':''2'' to it to have:



mydict[''b''] = ''2''
print mydict
