根据命令输出计算数字的平均值

import sys

def calculate_average(numbers):
    return sum(numbers) / len(numbers)

if __name__ == "__main__":
    # 从命令行参数获取数字
    numbers = [float(num) for num in sys.argv[1:]]
    average = calculate_average(numbers)
    print(f"The average is: {average}")

python script.py 10 20 30 40 50

The average is: 30.0

import sys

def calculate_average(numbers):
    if not numbers:
        raise ValueError("No numbers provided.")
    return sum(numbers) / len(numbers)

if __name__ == "__main__":
    try:
        # 从命令行参数获取数字
        numbers = [float(num) for num in sys.argv[1:]]
        average = calculate_average(numbers)
        print(f"The average is: {average}")
    except ValueError as e:
        print(f"Error: {e}")
    except Exception as e:
        print(f"An unexpected error occurred: {e}")
