HashMap，字典，Jason 三个格式区别

HashMap：

Map<String, Object> book = new HashMap<>();
book.put("name", "Hello Eve");
book.put("isbn", 199988);
book.put("author", "Tim");
System.out.println(book);

{author=Tim, isbn=199988, name=Hello Eve}

字典：

{5 : 1, 6 : 2,7 : 3 }

{'key1' : [1,"hello,tim","good"],'key2' : "Hello,everybody",'key3' : 13688995658, 'key4' : (136,139,138)}

例：

dict = {'key1' : [1,"hello,tim","good"],'key2' : "Hello,everybody",'key3' : 13688995658, 'key4' : (136,139,138)}
for key in dict:
    if type(dict[key]) == list or type(dict[key]) == tuple:
        for x in dict[key]:
            print(x)
