  • 71-使用函数编写数字游戏

    随机从1到100随机取2个数值进行随机的相加减,输错3次给答案。

    from random import randint,choice
    
    def add(x,y):  # 定义加函数
        return x + y
    
    def sub(x,y):  # 定义减函数
        return x - y
    
    def exam():
        cmds = {'+':add,'-':sub}  # 加减函数的字典
        nums = [randint(1,100) for i in range(2)]  # 随机取2个数值放在列表里
        nums.sort(reverse=True)  # 列表降序排列
        op = choice('+-')  # 随机选择加或者减
        result = cmds[op](*nums)  # 随机值相加减的结果
        prompt = "%s %s %s = " %(nums[0],op,nums[1])
        tries = 0
    
        while tries < 3:
            try:
                answer = int(input(prompt))  # 用户输入答案
            except:
                continue
    
            if answer == result:
                print("You are right!")
                break
    
            else:
                print("You are wrong!")
                tries += 1
        else:  # 猜对了直接跳出循环,3次全猜错了才执行,给出答案。
            print("%s %s" %((prompt,result)))
    
    if __name__ == '__main__':
        while True:
            exam()
            try:
                yn = input("Continue(y/n)? ").strip()[0]
                print(yn)
            except IndexError:
                continue
            except (KeyboardInterrupt,EOFError):
                print()
                yn = 'n'
            if yn in 'nN':
                break

    结果输出:

    62 - 29 = 20
    You are wrong!
    62 - 29 = 30
    You are wrong!
    62 - 29 = 50
    You are wrong!
    62 - 29 =  33
    Continue(y/n)? y
    y
    25 + 16 = 41
    You are right!
    Continue(y/n)? n
    n
