第1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2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3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(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4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
