Python 2.7：循环时的ArcPy游标

Question

我正在尝试使用Python中的while循环从属性表中打印条目，特别是高中设施名称。我可以使用for循环打印出高中名字，但是我错过了使用while循环的东西。

#code using for loop:
import arcpy


try:

    work = raw_input("Enter the full workspace path: ")
    arcpy.env.workspace = work

    fcs = "Schools.shp"

    whereClause = "\"FACILITY\" = 'HIGH SCHOOL'"
    searchCurs = arcpy.SearchCursor(fcs, whereClause, "", "", "")
    row = searchCurs.next()
    row.Name
    for row in searchCurs:
        print row.Name

except Exception as e:
    print "Error: " + str(e)
    print arcpy.GetMessages()
    arcpy.AddError(e)


#code using while loop: 

import arcpy

try:

work = raw_input("Enter the full workspace path: ")
arcpy.env.workspace = work

fcs = "Schools.shp"
field = "FACILITY"

whereClause = "\"FACILITY\" = 'HIGH SCHOOL'"
searchCurs = arcpy.SearchCursor(fcs, whereClause, "", "", "")
row = searchCurs.next()

while row:
    print(row.getValue(field)) 
    row = searchCurs.next


except Exception as e:
    print "Error: " + str(e)
    print arcpy.GetMessages()
    arcpy.AddError(e)

for循环脚本有效。如何使while循环起作用？

Answer 1

我明白了。我忘了（）在row.next之后。
