嵌套字典

嵌套字典的创建方法

例子如下：

all_data={}
dizhilevel={}
level={}
for line in lines[1:]:
name=line.split("\t")[0].split("-")[0].decode("utf-8")
dengji=line.split("\t")[0].split("-")[1]
value1=line.split("\t")[1]
value2=line.split("\t")[3]
value3=line.split("\t")[4]
value4=line.split("\t")[5]
value5=line.split("\t")[6]
value6=line.split("\t")[13]
# '0-48'=line.split("\t")[7]
# '0-72'=line.split("\t")[8]
# '6-12'=line.split("\t")[10]
# '12-18'=line.split("\t")[11]
# '18-24'=line.split("\t")[12]
# '12-24'=line.split("\t")[13]
# '24-36'=line.split("\t")[14]
# '36-48'=line.split("\t")[15]
# value=line.split("\t")[1:]
value={'0-1' : value1,'0-3':value2,'0-6': value3 ,'0-12':value4 ,'0-24':value5 ,'12-24':value6 }
# dizhilevel.setdefault={name:level}
dizhilevel.setdefault(name,level)
level.setdefault(dengji,{})
dizhilevel[name]=level
level[dengji]=value
