python命令语法不正确_Python 3.4.1脚本语法错误，arcpy和

我曾经在python 2.7中工作过，所以有一些新的东西，例如print函数有所不同。请原谅我的无知。我对编程也很陌生。

所以这是我的脚本，我不断收到错误，突出显示一些逗号或空格，并说有一个

SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 16-17: malformed \N character escape

码：

import arcpy

print("mosaic to new raster starting!")

env.workspace = "F:\GDAL"

arcpy.env.pyramid = "NONE"

arcpy.env.rasterStatistics = "NONE"

arcpy.env.compression = "JPEG 87"

arcpy.env.tileSize = "256 256"

print("Environment set")

RasterInput = "m_3511401_ne_11_1_20130731.jpg;m_3511401_nw_11_1_20130731.jpg;m_3511401_se_11_1_20130731.jpg;m_3511401_sw_11_1_20130731.jpg;"

print("Input set")

arcpy.MosaicToNewRaster_management(RasterInput,"F:\Pro_Projects\NAIP2013\raster.sde","MosaicFile1","","8_BIT_UNSIGNED","","3","LAST","FIRST")

print("mosaic done!")
