以下均为国防科技大学-胡卫东老师的实训项目内容答案，各位校友自取

第一关-While 循环与 break 语句

partcount = int(input())
electric = int(input())
count = 0
#请在此添加代码，当count < partcount时的while循环判断语句
#********** Begin *********#
while(count < partcount):
#********** End **********#
    count += 1
    print("已加工零件个数:",count)
    if(electric):
        print("停电了，停止加工")
        #请在此添加代码，填入break语句
        #********** Begin *********#
        break
        #********** End **********#
            

第二关-for 循环与 continue 语句

absencenum = int(input())
studentname = []
inputlist = input()
for i in inputlist.split(','):
   result = i
   studentname.append(result)
count = 0
#请在此添加代码，填入循环遍历studentname列表的代码
#********** Begin *********#
for student in studentname:
#********** End **********#
    count += 1
    if(count == absencenum):
        #在下面填入continue语句
        #********** Begin *********#
        continue
        #********** End **********#
    print(student,"的试卷已阅")

第三关-循环嵌套

studentnum = int(input())
#请在此添加代码，填入for循环遍历学生人数的代码
#********** Begin *********#
for student in range(0,studentnum):
#********** End **********#
    sum = 0
    subjectscore = []
    inputlist = input()
    for i in inputlist.split(','):
        result = i
        subjectscore.append(result)
    #请在此添加代码，填入for循环遍历学生分数的代码
    #********** Begin *********#
    for score in subjectscore:
    #********** End **********#
        score = int(score)
        sum = sum + score
    print("第%d位同学的总分为:%d" %(student,sum))

第四关-迭代器

List = []
member = input()
for i in member.split(','):
    result = i
    List.append(result)
#请在此添加代码，将List转换为迭代器的代码
#********** Begin *********#
IterList=iter(List)
#********** End **********#
while True:
    try:
        #请在此添加代码，用next()函数遍历IterList的代码
        #********** Begin *********#
        num=next(IterList)
        #********** End **********#
        result = int(num) * 2
        print(result)
    except StopIteration:
        break
