Python打印含\n的字符串元组时无法正常换行问题求解

问题根因 #

你的代码存在两处明显错误，是导致换行失效、判断不符合预期的直接原因：

• noRulesQuestion定义错误：你在括号内用逗号分隔多段带\n的文本，这种写法不会把多段文本拼接成一个完整字符串，而是生成了一个包含3个字符串元素的元组。当你给print()传入元组时，Python会输出元组的结构化表示形式，不会解析字符串内部的\n转义符，因此你会看到\n被原样打印在输出中。
• 分支判断逻辑错误：if rulesQuestion == "No" and "no"是典型的初学者逻辑写法错误，Python中非空字符串会被判定为布尔真，这行代码实际等价于if (rulesQuestion == "No") and True，用户输入小写no时根本无法进入对应分支。

修复方法 #

方案1（推荐）：用三引号直接定义多行字符串 #

三引号包裹的字符串会保留内部的自然换行，不需要手动插入\n，写法最简洁，同时修正判断逻辑兼容用户的大小写输入：

noRulesQuestion = """Each player rolls two dice. If the scores on the two dice are different, they are added. If they are the same then the score is increased be 50% (so two 3s would score a 9).
If one of the scores is greater than 12 the other player automatically wins.
If one of the scores is equal to twelve, that player wins."""

while True:  
    rulesQuestion = input("Do you know the rules? Type Yes or No: ").strip()
    # 统一转小写判断，兼容No、NO、no等各种大小写输入
    if rulesQuestion.lower() == "no":
        print(noRulesQuestion)      
        break

方案2：保留原有单行拆分写法，去掉分隔用的逗号 #

Python会自动拼接括号内相邻的字符串字面量，只要去掉逗号，就不会生成元组，\n也能正常被解析：

# 注意：所有文本段之间不要加逗号，相邻字符串会自动拼接为一个完整字符串
noRulesQuestion = ("Each player rolls two dice. If the scores on the two dice are different, they are added. If they are the same then the score is increased be 50% (so two 3s would score a 9).\n"
"If one of the scores is greater than 12 the other player automatically wins.\n" 
"If one of the scores is equal to twelve, that player wins.")
