{'key1':'value3','key2':'value4'}]}}
这是将密钥添加到字典主要局部的代码：for x in range(len(mydict)):
number = 1+x
str(number)
mydict[d'index']=number
print mydict
#out: {d'index':d'1',d'a'{d'result':[...]}}
我想将新的键和值添加到方括号内的小词典中：{'a':{'result':[{'key1':'value1',...,'index':'number'}]}}
假如我尝试在for loop的最后一行中添加更多层，则会呈现回溯错误：Traceback (most recent call last):
File "C:27\program.py", line 34, in
main()
File "C:\Python27\program.py", line 23, in main
mydict['a']['result']['index']=number
TypeError: list indices must be integers, not unicode
