[求助] ArcGIS属性计算器，怎么让属性参与计算？ 已有1人参与

if (!MEAN_ASP!>= 22.5) and (!MEAN_ASP!<67.5):
A='NE'
elseif (!MEAN_ASP!>= 67.5) and (!MEAN_ASP!<112.5):
A='E'
elseif (!MEAN_ASP!>= 112.5) and (!MEAN_ASP!<157.5):
A='SE'
elseif (!MEAN_ASP!>= 157.5) and (!MEAN_ASP!<202.5):
A='S'
elseif (!MEAN_ASP!>= 202.5) and (!MEAN_ASP!<247.5):
A='SW'
elseif (!MEAN_ASP!>= 247.5) and (!MEAN_ASP!<292.5):
A='W'

A='NW'
else:
A='N'

你这是VB的脚本代码吧，我建议直接用字段计算器一步一步算！

def zz(A):
  if (A>= 22.5) and (A<67.5):
    return 'NE'
  elif (A>= 67.5) and (A<112.5):
    return 'E'
  elif (A>= 112.5) and (A<157.5):
    return 'SE'
  elif (A>= 157.5) and (A<202.5):
    return 'S'
  elif (A>= 202.5) and (A<247.5):
    return 'SW'
  elif (A>= 247.5) and (A<292.5):
    return 'W'
  elif (A>= 292.5) and (A<337.5):
    return 'NW'
  else:
    return 'N'
