错误：'module'对象没有属性（ArcMap 10.1）
我刚开始学习用Python来创建工具箱。我在看这个视频 http://www.youtube.com/watch?v=B6zbzPOnYYQ，想跟着它的步骤来做我的第一个Python工具箱。
我试着用视频里（从24:00到27:00）的代码来创建这个工具箱。但是，当我写完完全一样的代码并尝试运行时，出现了这个错误：
Traceback (most recent call last): File "<string>", line 24,
in getParameterInfoAttributeError: 'module' object has no attribute 'Paramter'
下面是代码的展示
import arcpy
class Toolbox(object):
def __init__(self):
"""Define the toolbox (the name of the toolbox is the name of the
.pyt file)."""
self.label = "Calculate Geomtery"
self.alias = "Geometry"

self.tools = [CalculateGeometry]

如果有人能帮忙，我会非常感激。
