在 Python 中打印行

Question

我已经使用游标创建了一个新属性 table python 和 arcpy 但是当我尝试从属性数据（例如国家/地区、城市和人口）打印行时只有一个将打印城市。

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

Selecting locations

Removing the data that does not meet the requirements

[u'Canada', 25000.0]

Finished identifying the cities

提前感谢您的任何建议！

要在循环中打印 each 行，print row 语句需要在循环内。

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()

如果您只想打印已删除的行，请将 print 语句放在 if/elif 条件中。
