python程序的无限循环

Question

我对此代码有疑问，该程序应允许您输入学生，直到通过次数达到8或学生总数达到10为止。但是目前，它一直在要求输入，因此存在无限循环。 我该如何解决这个问题？

total_students=0
student_passes=0
student_failures=0

while (total_students <= 10) or (student_passes != 8):
        result=int(input("Input the exam result: "))
        if result>=50:
            student_passes = student_passes + 1
        else:
            student_failures = student_failures + 1
        total_students = total_students + 1

 print (student_passes)
 print (student_failures)

 if student_passes >= 8:
     print ("Well done")

Answer 1

将或更改为和。 两者都成立的同时，您继续：

total_students=0
student_passes=0
student_failures=0

while (total_students != 10) and (student_passes != 8): # != or <
        result=int(input("Input the exam result: "))
        if result>=50:
            student_passes += 1
        else:
            student_failures += 1
        total_students +=1

print (student_passes)
print (student_failures)

Answer 2

您可能需要重新访问代码。 我不是python专家，但是我相信您应该修改while循环的条件。

例如while（total_students <= 10）或（student_passes <= 8）：这将解决您的问题。

total_students=0
student_passes=0
student_failures=0

while (total_students <= 10) or (student_passes <= 8):
        result=int(input("Input the exam result: "))
        if result>=50:
            student_passes = student_passes + 1
        else:
            student_failures = student_failures + 1
        total_students = total_students + 1

 print (student_passes)
 print (student_failures)

 if student_passes >= 8:
     print ("Well done")

Answer 3

您应该使用和代替或满足您的要求。

total_students=0
student_passes=0
student_failures=0

while (total_students <= 10 and student_passes < 8):
        result=int(input("Input the exam result: "))
        if result>=50:
            student_passes = student_passes + 1
        else:
            student_failures = student_failures + 1
        total_students = total_students + 1

print (student_passes)
print (student_failures)

if student_passes >= 8:
    print ("Well done")
