以下是我的问题：

创建一个名为“numSchools”的函数，用于计算特定类型的学校。该函数应具有三个输入参数，(1) 工作区字符串，(2) shapefile 名称字符串，(3) 设施类型字符串（例如“HIGH SCHOOL”），以及一个输出参数， (1) shapefile 中该设施类型的学校数量的整数。

import arcpy

shapefile = "Schools.shp"
work = r"c:\Scripts\Lab 6 Data"
sTyp = "HIGH SCHOOL"

def numSchools(work, shapefile, sTyp):

    whereClause = "\"FACILITY\" = 'HIGH SCHOOL' " # where clause for high schools
    field = ['FACILITY']
    searchCurs = arcpy.SearchCursor(shapefile, field, whereClause)
    row = searchCurs.next()
    for row in searchCurs:
    # using getValue() to get the name of the high school
    value = row.getValue("NAME")

    high_schools = [row[0] for row in arcpy.SearchCursor(shapefile, field, whereClause)]
    count = arcpy.GetCount_management(high_schools)
    return count

numSchools(work, shapefile, sTyp)
print ("There are a total of: "),count

所以这是我运行完美的代码，但它是通过脚本完成的。我需要把它包装成一个python函数。（我的弱点）。我的代码的最后一行似乎有一些问题。`

我不太确定如何格式化最后一行代码以阅读（共有 29 所高中），同时包含必要的参数。

您需要显式传递参数。

count = numSchools(work, shapefile, sTyp)
print("There are a total of: ", count)
