第2题:
以下关于Python自带数据结构的运算结果中正确的是哪一项?
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了一个值为90了。
D.scores = {'Jack': 90, 'Mike': 80, 'Jay': 85, 'Bill': 60}; sorted(scores.keys())的运算结果是 ['
