程序段如下：import jsondt = {'b':2,'c':4,'a':6}s1 = json.dumps(dt)s2 = json.dumps(dt,sort_keys=True,indent=4)print(s1==s2)print函数输出的结果是( ) A: false B: False C: True D: true

程序段如下：import jsondt = {'b':2,'c':4,'a':6}s1 = json.dumps(dt)print(s1)print函数输出的结果是( ) A: {"a":6,"b":2,"c":4} B: {"a":6,"b":2,"c":4} C: {2, 4, 6} D: {"b","c" ,"a"}

程序段如下：import jsondt = {'b':2,'c':4,'a':6}s2 = json.dumps(dt,sort_keys=True,indent=4)print(type(s2))print函数输出的结果是( ) A: <class 'dict'> B: <class 'str'> C: <class 'tuple'> D: <class 'list'>

程序段如下：import jsondt = {'b':2,'c':4,'a':6}s2 = json.dumps(dt,sort_keys=True,indent=4)dt1 = json.loads(s2)print(type(dt1))print函数输出的结果是( ) A: <class 'list'> B: <class 'dict'> C: <class 'tuple'> D: <class 'str'>
