# 随机生成一个口算题及其正确结果的函数
def genOneExercise():
	opt = random.randint(0, 1)  # 在0和1中随机取一个值
	if opt == 1:	# 如果随机得到的是 1，我们就生成加法口算题
		a = random.randint(1, 99)	# 注意这里是 99
		b = random.randint(1, 100-a)	# 这是保证百以内加法的地方
		result = a + b
		#return a, opt, b, result
		return " {a} + {b} = ".format(a=a, b=b), result
	else:			# 如果随机得到的是 0，我们就生成减法口算题
		a = random.randint(1, 100)
		b = random.randint(1, 100)
		if a > b:
			result = a - b
			# 和上篇文章里代码比， 此处已把返回数据格式简化
			return " {a} - {b} = ".format(a=a, b=b), result
		else:
			result = b - a	# 这里是避免出现减数不够的地方
			# 和上篇文章里代码比， 此处已把返回数据格式简化
			return " {a} - {b} = ".format(a=b, b=a), result
