在while循环中计算平均值

# 初始化变量

# 假设我们有一个函数 get_next_number() 来获取下一个数值
def get_next_number():
    # 这里可以是任何逻辑，比如从列表中取值，或者从用户输入获取
    pass

# 使用 while 循环来累加数值并计数
while number is not None:  # 假设 None 表示没有更多的数值
    number = get_next_number()
    if number is not None:
        sum_of_numbers += number
        count += 1

# 计算平均值
if count > 0:
    average = sum_of_numbers / count
    print(f"The average is: {average}")

    print("No numbers were provided.")

        sum_of_numbers += number
