设用列表来描述分数，scores = &#91;88, 52, 96, 75, 97, 100&#93;。以下选项中，哪些能够实现遍历列表里的分数，并在屏幕上打印输出（所有分数在一行打印，分数和分数之间用空格间隔）？ 即，输出结果为：88 52 96 75 97 100 A: scores = [88, 52, 96, 75, 97, 100] <br> for score in scores: print(score, end=' ') B: scores = [88, 52, 96, 75, 97, 100] <br> i = 0 while i < len(scores): print(scores[i], end = ' ') i += 1 C: scores = [88, 52, 96, 75, 97, 100] <br> for score in scores: print(score, end=', ') D: scores = [88, 52, 96, 75, 97, 100] <br> i = 0 while i < len(scores): print(scores[i], end = ', ') i += 1

社会主义的本质是：解放生产力，[input=type:blank,size:5][/input]，消灭剥削，消除两极分化，最终达到[input=type:blank,size:5][/input]。

以下关于 Python自带数据结构的运算结果中正确的是( )。 A: scores ={' Jack ': 90,' Mike ': 80, ' Jay': 85,'Bill ': 60};del scores['Bill'];len(scores)的结果是6。 B: scores ={' Jack ': 90,' Mike ': 80, ' Jay': 85,'Bill ': 60};s=dict(Jack=90,Mike=80,Jay=85,Bill=60);则scores==s判断结果是 False。 C: scores ={' Jack ': 90,' Mike ': 80, ' Jay': 85,'Bill ': 60},无法执行命令scores['Bill']=90,因为原来的字典中已经有一个值为90了。 D: scores ={' Jack ': 90,' Mike ': 80, ' Jay': 85,'Bill ': 60};sorted(scores.keys())的运算结果是['Bill','Jack','Jay','Mike']。
