遍历字典的kEy

aDict = {'key1':'value1', 'key2':'value2', 'key3':'value3'} print '-----------dict-------------' for d in aDict: print "key: %s" %(d, )

有很多方法 1.赋值给数组然后遍历 2.for j=0 to dic.count a=dic.keys()(j) next j 3.for each a in dic.keys next a

看你要拿到什么了,list?数组?还是一个string? Dictionary strDic = new Dictionary(); strDic.Add("a", "aa"); strDic.Add("bb", "aa"); strDic.Add("vvv", "aa"); strDic.Add("aff", "aa"); strDic.Keys.ToList(); strDic.Keys.ToArray(); ...

见如下代码: Sub test()Dim dict' 创建DictionarySet dict = CreateObject("Scripting.Dictionary")' 增加项目dict.Add "A", 300dict.Add "B", 400dict.Add "C", 500' 对字典进行循环k = dict.keysv = dict.ItemsFor i = 0 To dict.Count - 1 K...

递归。 用这个函数把dict里面的所有value用递归的方法提取到一个空list里面 def dict2flatlist(d,l): print(d) for x in d.keys(): if type(d[x]) == dict: dict2flatlist(d[x],l) else: l.append(d[x]) d = {1:"a",2:"b",3:{4:"c",5:"d",6:{7:"...

有啊 比如定义了变量d为字典变量 那么 for each a in d.keys msgbox a next 或者for j=0 to d.count -1 msgbox d.keys()(j) next

python的字典有个keys()的方法,在python2.x中返回的是个列表,在python3.x中返回的是个迭代器,这2个类型都是可以遍历的,用法很简单,看下面的python代码 d={'1':2,'3':4,'a':'b','c':'d'}for item in d.keys(): print item

json是种常用数据传输格式,js怎么解析json格式的数据呢,请参阅下面的代码: [html] view plain copy print? var data = '{"return_code":0,"return_message":"success","data":{"data":[{"id":"1","question":"公主令牌在哪交?"},{"id":"2","...

不知道你是不是这个意思, 字典调用values()方法会返回Value值所构成的列表,通过两个循环就能遍历字典里的列表 data = {'a':[1,2,3],'b':[4,5,6]}for l in data.values(): for item in l: print item

>>> mapper{1: ['a', 'b', 'c'], 2: ['d'], 3: ['e'], 4: ['f', 'g'], 5: ['h'], 6: ['i'], 7: ['a', 'g']}>>> def itertransfer(mapper):... for k, values in mapper.items():... for v in values:... yield (k, v)... >>> for k, v in itertr...
