Python面向过程五十行左右代码

Python 中的面向过程编程主要关注函数和数据处理，下面是一个简单的示例，通过函数实现一个计算阶乘的过程，大约五十行左右：

def factorial(n):
    # 基线条件: 阶乘为1对于0和1
    if n == 0 or n == 1:
        return 1

    # 递归函数: 计算 n 的阶乘
    else:
        return n * factorial(n - 1)

# 函数应用示例
def process_numbers(numbers):
    result = []
    for num in numbers:
        if isinstance(num, int) and num >= 0:
            result.append(factorial(num))
        else:
            print(f"Invalid input: {num} is not an integer or is negative.")
    return result

# 用户输入示例
if __name__ == "__main__":
    user_input = [int(i) for i in input("Enter a list of non-negative integers separated by space: ").split()]
    print("Factorial of each number:")
    print(process_numbers(user_input))
