请编写Python程序完成以下要求：有如下数据： scores={'Tom':{'Chinese':95,'Math':98}, 'Jack':{'Chinese':85,'Math':85}, 'Jerry':{'Chinese':56,'Math':36}, 'Rose':{'Chinese':87,'Math':85}, 'Mary':{'Chinese':97,'Math':95} } 请按要求分别完成以下任务： （1）计算这几位同学的语文和数学成绩的平均分（保留1位小数）并输出。 （2）找出两门课都不及格（<60）的学生，并按照字母表从A至Z的顺序逐一输出他们的姓名。 （3）找出两门课的平均分在90分以上（>90）的学生，并按照字母表从A至Z的顺序逐一输出他们的姓名。 输入格式： 无输入 输出格式： 每个任务的输出结果分别占1行，请直接拷贝输出样例的文字到程序中使用 输入样例： 无 输出样例： The Chinese average score is 88.8 The Math average score is 88.8 Students failed in both courses are:Jack,Tom,…… Students with average scores of more than 90 in the two courses are:Jack,Tom,……
