python 从命令行接收两个整数参数，并计算它们的和

import sys

# print(sys.argv)
def main():
    # 检查命令行参数的数量
    if len(sys.argv) != 3:
        print("Usage: python t1.py <num1> <num2>")
        sys.exit(1)

        # 将命令行参数转换为整数
    try:
        num1 = int(sys.argv[1])
        num2 = int(sys.argv[2])
    except ValueError:
        print("Both arguments must be integers.")
        sys.exit(1)

        # 计算和并打印
    sum_result = num1 + num2
    print(f"The sum of {num1} and {num2} is: {sum_result}")


if __name__ == "__main__":
    main()
