var jsondata=[{"男":4,"女":3,"不详":0},{"男one":23,"女two":12,"不详two":10}];//对于json形式的数组 ,我们得到其中某个键对应的值是很容易的,//例如得到男对应的值var man=jsondata[0].男:一:循环得到json的键和值但是有些情况下 我们需要得到建和值eg:得到json数组中第一个元素的键值 for (va
此程序的目的在于,正确而简单的访问字典的键与值 favorite_languages={ 'jen':['python','c'], 'sarah':['c'], 'edward':['ruby','go'], 'phil':['python','java'], } #古老的方法访问字典中键与值 for element in favorite_languages: print(element +"'s favorite languages are:") print("\t&q
