Question

我有这段代码：

 def begin(): # the main attraction.
    print("Select difficulty level\n")
    print("E - Easy. Data set is 5 numbers long, and the set is sorted\n")
    print("M - Medium. Data set is 7 numbers long and the set is sorted\n")
    print("H - Hard. Data set is 10 numbers long and the set is not sorted\n")
    difficultySelect = input()
    if difficultySelect == "E" or "e":
        worksheet.beginGameLoop("easy")
    elif difficultySelect == "M" or "m":
        worksheet.beginGameLoop("med")
    elif difficultySelect == "H" or "h":
        worksheet.beginGameLoop("hard")
def beginGameLoop(gameDifficulty):
    if gameDifficulty == "easy":
        length = 5
        sorting = True
    elif gameDifficulty == "med":
        length = 7
        sorting = True
    elif gameDifficulty == "hard":
       length = 10
       sorting = False
       for questions in range(10):
           invalidPrinted = False
           questions, answer, qType = worksheet.createQuestion(length, sorting)

当我运行它时，它似乎停留在easy-mode的变量上。可能是什么问题？编辑：整个事情是here.

Answer 1

问题在于：

if difficultySelect == "E" or "e":
    worksheet.beginGameLoop("easy")
elif difficultySelect == "M" or "m":
    worksheet.beginGameLoop("med")
elif difficultySelect == "H" or "h":

它应该是：

if difficultySelect == "E" or difficultySelect == "e":
    worksheet.beginGameLoop("easy")
elif difficultySelect == "M" or difficultySelect == "m":
    worksheet.beginGameLoop("med")
elif difficultySelect == "H" or difficultySelect == "h":

甚至更好：

if difficultySelect in ("E", "e"):
    worksheet.beginGameLoop("easy")
elif difficultySelect in ("M", "m"):
    worksheet.beginGameLoop("med")
elif difficultySelect in ("H", "h"):

声明if x == 'a' or 'b'将永远为真。在Python中，or语句的结果是False或第一个不是False的计算语句的值。因此，在您的情况下，True如果difficultySelect等于E或e，则为e。并且False始终不是{{1}} - 这就是为什么始终满足第一个条件。

Answer 2

看起来你的for循环缩进太多了。

if gameDifficulty == "easy":
    length = 5
    sorting = True
elif gameDifficulty == "med":
    length = 7
    sorting = True
elif gameDifficulty == "hard":
    length = 10
    sorting = False

for questions in range(length):
    invalidPrinted = False
    questions, answer, qType = worksheet.createQuestion(length, sorting)
