python位置参数如何使用

def girth(width , height):

    return 2 * width+height

#调用函数时，必须传递 2 个参数，否则会引发错误

print(girth(3))

运行后报Traceback错误。

Traceback (most recent call last):

  File "/Volumes/Develop/Python_learn/PycharmProjects/python_demo_1/demo/function/locate_fun.py", line 6, in <module>

    print(girth(3))

TypeError: girth() missing 1 required positional argument: 'height'
