Python条件语句问题求助：输入No未执行预期分支逻辑

你的代码核心问题是完全没用到用户输入的answer变量，反而用了固定值的a做判断，导致不管用户输入什么，都会执行OK, lets play...的分支。另外else里的b == "No"只是个无效的比较操作，起不到任何作用。

修正后的代码 #

name = input("What is your name?\n")
age = input("How old are you?\n")
country = input("Where are you from?\n")
print(f"Hi {name} I see you are {age} and you were born in {country}")

answer = input("Do you want to play a game?\n")

if answer == "Yes":
    print("awesome")
    print("OK, lets play...")
else:
    print("Thank you for your time, goodbye")

关键修改点 #

• 删掉了没用的a和b变量，直接判断用户输入的answer值
• 把print("awesome")移到了Yes的分支里，这样只有用户同意玩游戏时才会打印
• 去掉了else里无效的b == "No"语句，直接执行告别逻辑
• 用了f-string格式化输出（f"Hi {name}..."），比字符串拼接更简洁易读

现在测试输入No，程序会输出：

What is your name?
Paul
How old are you?
49
Where are you from?
UK
Hi Paul I see you are 49 and you were born in UK
Do you want to play a game?
No
Thank you for your time, goodbye
