两个同时运行的 while 循环

Question

我正在尝试获取第一个 while True 循环来提问。如果用 'y' 回答是，它会继续到第二个 while test_score != 999: 循环。如果输入 y 以外的任何内容，它应该停止。一旦第二个 while 循环运行s，用户输入他们的考试成绩并输入 'end' 当他们完成并执行代码时，第一个 "while True" 循环应该询问用户是否愿意输入另一组考试成绩。如果输入 'y'，则它会重新完成整个过程。我知道第二个是嵌套的 while 循环。但是，我按照 python 缩进规则在 PyCharm 中缩进了它，它仍然告诉我我有缩进错误并且不会运行程序。这就是他们在下面彼此排成一行的原因。话虽如此，当我运行它如下所列时，它给出了以下答案：

Enter test scores
Enter end to end the input
==========================
Get entries for another set of scores? y
Enter your information below
Get entries for another set of scores? n
((When I type in 'n' for no, it shows the following:))
Thank you for using the Test Scores application. Goodbye!
Enter test score: 80 (I entered this as the input)
Enter test score: 80 (I entered this as the input)
Enter test score: end (I entered this to stop the program)
==========================
Total score: 160
Average score: 80

当我回答 'y' 时，它开始了一个连续的循环。当我回答'n'时，它确实给出了打印语句。然而，它也允许我输入我的考试成绩，输入结束并执行程序。但是，它也没有询问用户是否要输入一组新的考试成绩。对我哪里出错有什么建议吗？

print("The Test Scores application")
print()
print("Enter test scores")
print("Enter end to end input")
print("======================")

# initialize variables
counter = 0
score_total = 0
test_score = 0

while True:
    get_entries = input("Get entries for another set of scores?  ")
    if get_entries == 'n':
        print("Thank you for using the Test Scores application. Goodbye!")
        break
    else:
        print("Enter your information below")
        continue

counter = 0
score_total = 0
test_score = 0

while test_score != 999:
    test_score = input("Enter test score: ")

    if test_score == 'end':
        break
    elif (int(test_score) >= 0) and (int(test_score) <= 100):
        score_total += int(test_score)
        counter += 1
    elif test_score == 999:
        break
    else:
        print("Test score must be from 0 through 100. Score discarded. Try again.")

    # calculate average score
average_score = round(score_total / counter)

# format and display the result
print("======================")
print("Total Score:", score_total,
      "\nAverage Score:", average_score)

while 循环应该嵌套以包含重复条目

print("The Test Scores application")
print()
print("Enter test scores")
print("Enter end to end input")
print("======================")

# initialize variables
counter = 0
score_total = 0
test_score = 0

while True:
    get_entries = input("Get entries for another set of scores?  ")
    if get_entries == 'n':
        print("Thank you for using the Test Scores application. Goodbye!")
        break
    else:
        print("Enter your information below")
        counter = 0
        score_total = 0
        test_score = 0

        while test_score != 999:
            test_score = input("Enter test a score: ")

            if test_score == 'end':
                break
            elif (int(test_score) >= 0) and (int(test_score) <= 100):
                score_total += int(test_score)
                counter += 1
            elif test_score == 999:
                break
            else:
                print("Test score must be from 0 through 100. Score discarded. Try again.")

# calculate average score
        average_score = round(score_total / counter)

# format and display the result
        print("======================")
        print("Total Score:", score_total,
              "\nAverage Score:", average_score)

输出：

The Test Scores application

Enter test scores
Enter end to end input
======================

Get entries for another set of scores?  y
Enter your information below

Enter test a score: 60

Enter test a score: 80

Enter test a score: 90

Enter test a score: 70

Enter test a score: end
======================
Total Score: 300 
Average Score: 75

Get entries for another set of scores?  y
Enter your information below

Enter test a score: 80

Enter test a score: 80

Enter test a score: end
======================
