    一年中的12个月份的月最大合成（mvc）数据放在“F:\\Vegetation Change\\Data\\GIMMS Data\\1MVC\\"，数据名称格式为mvc_198801,mvc_198802........mvc_198812。处理年份为1981-2006，代码为：

import arcpy
arcpy.CheckOutExtension("spatial")
for i in range(1981,2007):
    a1 = "F:\\Vegetation Change\\Data\\GIMMS Data\\1MVC\\"+"mvc_"+str(i)+"01"
    a2 = "F:\\Vegetation Change\\Data\\GIMMS Data\\1MVC\\"+"mvc_"+str(i)+"02"
    a3 = "F:\\Vegetation Change\\Data\\GIMMS Data\\1MVC\\"+"mvc_"+str(i)+"03"
    a4 = "F:\\Vegetation Change\\Data\\GIMMS Data\\1MVC\\"+"mvc_"+str(i)+"04"
    a5 = "F:\\Vegetation Change\\Data\\GIMMS Data\\1MVC\\"+"mvc_"+str(i)+"05"
    a6 = "F:\\Vegetation Change\\Data\\GIMMS Data\\1MVC\\"+"mvc_"+str(i)+"06"
    a7 = "F:\\Vegetation Change\\Data\\GIMMS Data\\1MVC\\"+"mvc_"+str(i)+"07"
    a8 = "F:\\Vegetation Change\\Data\\GIMMS Data\\1MVC\\"+"mvc_"+str(i)+"08"
    a9 = "F:\\Vegetation Change\\Data\\GIMMS Data\\1MVC\\"+"mvc_"+str(i)+"09"
    a10 = "F:\\Vegetation Change\\Data\\GIMMS Data\\1MVC\\"+"mvc_"+str(i)+"10"
    a11 = "F:\\Vegetation Change\\Data\\GIMMS Data\\1MVC\\"+"mvc_"+str(i)+"11"
    a12 = "F:\\Vegetation Change\\Data\\GIMMS Data\\1MVC\\"+"mvc_"+str(i)+"12"
    out = "F:\\Vegetation Change\\Data\\GIMMS Data\\2Max\\max_"+str(i)
    arcpy.gp.CellStatistics_sa((a1,a2,a3,a4,a5,a6,a7,a8,a9,a10,a11,a12), out, "MAXIMUM", "DATA")
    print(str(i) +" has done")
