Python中打印行

Question

我使用游标创建了一个新的属性表，使用python和arcpy，但是当我试图从属性数据（如国家、城市和人口）打印行时，只打印一个城市。

arcpy.CopyRows_management (folder_path + '\NA_Cities.shp', folder_path + '\Select_Cities.dbf')
fc = folder_path + '\Select_Cities.dbf'

The_cursor = arcpy.da.UpdateCursor(fc, ['CNTRY_NAME', 'Population'])
for row in The_cursor:
    if row[0] == 'United States' and row[1] < 8000000:
        The_cursor.deleteRow()
    elif row [0] == 'Mexico' and row[1] < 8000000:
        The_cursor.deleteRow()
    elif row[0] == 'Canda' and row[1] < 3000000:
        The_cursor.deleteRow()
print row

这是我的结果

^{pr2}$

谢谢您的任何建议！

要打印循环中的每个行，print row语句需要在循环中。在

for row in The_cursor:
    print row
    if row[0] == 'United States' and row[1] < 8000000:
        The_cursor.deleteRow()
    elif row [0] == 'Mexico' and row[1] < 8000000:
        The_cursor.deleteRow()
    elif row[0] == 'Canada' and row[1] < 3000000:
        The_cursor.deleteRow()

如果只想打印已删除的行，请将print语句放在if/elif条件语句中。在
