[Tutor] Changing spatial reference of shapefiles in folder and exporting to new folder

[Michael Omohundro]

I want to assemble a script to: 1) input a folder with shapefiles with
different coordinate systems, 2) allow the user through a toolbox script to
choose a desired coordinate system, and then 3) export all the shapefiles
with the new coordinate system to a new folder.

So the problem is I don't know how to get the user to choose the coordinate
system they want when I create the script in toolbox.

Here is my code:

import arcpy


arcpy.env.workspace = arcpy.GetParameterAsText(0)

fcList = arcpy.ListFeatureClasses()

try:

    inFolder = arcpy.ListFeatureClasses()

    template = arcpy.GetParameteAsText(1)

    outFolder = arcpy.GetParameterAsText(2)


arcpy.AddMessage(template)

srf = arcpy.Describe(template).spatialReference.name


for fc in fcList:

    if srf.Name == "Unknown":

        # skip

        continue

    else:

        arcpy.Describe(fc).spatialReference.name != srf.name:
arcpy.Project_management (fc, outFolder + "\\" + fc, desc,
{transform_method}, {in_coor_system})


#

I have attached the window I am making in the toolbox to this email.

I also get this error when I run the script in the toolbox:

SyntaxError: invalid syntax (Final_Proj_DRAFT.py, line 16)Failed to
execute (SpatRefAutomation).

Line 16 of the code reads:

spatialRef = arcpy.Describe(inputFolder).spatialReference

Please help me.
