运行ArcPy代码时出现AttributeError: 'module'对象无'point'属性求助

Hey there, let's break down and fix the error you're hitting in your ArcPy code!

The Root Cause #

The error AttributeError: 'module' object has no attribute 'point' boils down to Python being case-sensitive. ArcPy's point geometry class is named Point (with an uppercase P), not point (lowercase p). You’re trying to access a lowercase version that doesn’t exist in the ArcPy module.

How to Fix It #

Anywhere in your code where you attempt to create a point object, replace arcpy.point() with arcpy.Point(). For example:

# Wrong
pt = arcpy.point(x_coord, y_coord)

# Correct
pt = arcpy.Point(x_coord, y_coord)

Bonus: Quick Fix for Your Area Calculation Function #

I spotted a small potential bug in your polylineArea function too:

• The function accepts parameters x and y, but you reference xlist inside the function. You likely meant to use the x parameter instead:

  def polylineArea(x, y):
      count = len(x)  # Updated from len(xlist)
      area = 0
      j = count - 1
      for i in range(0, count):
          area += ((x[j] + x[i]) * (y[j] - y[i]))
          j = i
      return area * .5
  

Key ArcPy Tip #

All ArcPy geometry classes (like Point, Polyline, Polygon, SpatialReference) use camel-case naming with the first letter capitalized. Double-check the case whenever you use these classes to avoid similar attribute errors.
