python程序的無限循環

Question

我對此代碼有疑問，該程序應允許您輸入學生，直到通過次數達到8或學生總數達到10為止。但是目前，它一直在要求輸入，因此存在無限循環。 我該如何解決這個問題？

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

將或更改為和。 兩者都成立的同時，您繼續：

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

您可能需要重新訪問代碼。 我不是python專家，但是我相信您應該修改while循環的條件。

例如while（total_students <= 10）或（student_passes <= 8）：這將解決您的問題。

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

您應該使用和代替或滿足您的要求。

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")
