python 嵌套字典取值增强版

def getdictvalue(d,code):
    result=[]
    if isinstance(d, dict) :
        try:
            value = d[code]
            result.append(value)
        except Exception as e:
            pass
        for valuedd in d.values():
            if isinstance(valuedd,dict):
                yied_result=getdictvalue(valuedd,code)
                if len(yied_result) != 0:
                    result.append(getdictvalue(valuedd,code))
            elif isinstance(valuedd,(list,tuple)):
                for item in d:
                    valueitem=getdictvalue(valuedd,code)
                    if valueitem !="None" and valueitem is not  None and  len(valueitem)!=0:
                        if valueitem not in result:
                            result.append(valueitem)
         
    elif isinstance(d, (list, tuple)):
            for item in d:
                value=getdictvalue(item,code)
                if value !="None" and  value is not None and  len(value)!=0:
                    if value not in result:
                        result.append(value)
    return result

　　由于返回时list，经过层层嵌套，list是复杂的，封装一个，增加一个list转换

class listchangetype(object):
  """对于查找后的list的数据的清洗"""
  def __init__(self):
    self.arg = []
  def make(self,listone):
    for i in listone:
      if isinstance(i,(type,list)):
        for l in i:
          self.make(i)
      else:
        if i not in self.arg:
          self.arg.append(i)
    return self.arg
