cmd.py:
# 导入argparse包
import argparse
import math
# 创建ArgumentParser实例,设置解析器
parser = argparse.ArgumentParser(description=‘Find the sum of two parameters‘,)
# 添加参数项，默认类型为str
parser.add_argument(‘-r‘, ‘--radius‘, type=int, metavar=‘‘, required=True, help=‘Radius of Cylinder‘)
parser.add_argument(‘-H‘, ‘--heights‘, type=int, metavar=‘‘, required=True, help=‘Height of Cylinder‘)
args = parser.parse_args()
def cylinder_volume(radius, heights):
vol = math.pi * (radius ** 2) * heights
return vol
if __name__ == "__main__":
volume = cylinder_volume(args.radius, args.heights)
print(volume)
命令行:
python cmd.py --help
结果：
python cmd.py -r 1 -H 2
结果：
