如何將第二個代碼塊中的布爾值分配給python中的第一個縮進塊？

Question

當我在第5個塊中分配out_of_marks_limit = True時，我希望if語句的第一個塊為“True”，並且我不希望代碼循環或再詢問用戶。

在其他編程語言中，縮進用於使程序看起來很好。 但是因為python只檢查第一個塊到相同縮進的條件，所以我不能將2個代碼塊的布爾值分配給第一個塊。 這就是我想說的。

我是一名中級程序員，這個程序僅用於練習目的。

a = int(input("Enter no. of subjects: "))
count = 1
d = 0
out_of_marks_limit = False          #I want the out_of_limit to be True
if a <= 10:
    if not out_of_marks_limit:
        if count <= a:
            for c in range(a):
                b = float(input("Enter mark of subject " + str(count) + ": "))
                if b <= 100:        #If this condition went false then it will skip to else statement
                    d += b
                    count += 1
                    if count > a:
                        cal = round(d/a, 2)
                        print("Your percentage is " + str(cal) + "%")
                else:
                    out_of_marks_limit = True #So this boolean value should passed to the first line of code
                    print("Marks enter for individual subject is above 100")
else:
    print("Subject limit exceeded")

我希望輸出打印（“單個主題的標記輸入超過100”），如果out_of_marks_limit為True並且不想再循環

我認為您可以使用while循環來檢查out_of_marks_limit條件：

a = int(input("Enter no. of subjects: "))
count = 1
d = 0
out_of_marks_limit = False          #I want the out_of_limit to be True

while not out_of_marks_limit:
    if a <= 10:
        if not out_of_marks_limit:
            if count <= a:
                for c in range(a):
                    b = float(input("Enter mark of subject " + str(count) + ": "))
                    if b <= 100:        #If this condition went false then it will skip to else statement
                        d += b
                        count += 1
                    if count > a:
                        cal = round(d/a, 2)
                        print("Your percentage is " + str(cal) + "%")
                    else:
                        out_of_marks_limit = True #So this boolean value should passed to the first line of code
                        print("Marks enter for individual subject is above 100")
else:
    print("Subject limit exceeded")
