Script to Copy File in Modelbuilder

cwh

Hi all,

I have a very simple python script to copy a file from one location to another:

import shutil

shutil.copy("c:/chris/Test1/CitizenComments.mxd" , "c:/chris/test2/CitizenComments.mxd")

If I take this script and put it in a model builder model, what change would I have to make to the code so that I could have a parameter in the model where a user could enter an index string to be appended to the front of the file name?

Thanks!

Chrs

I suggest reading the help about how to set up input and output parameters to scripts. Once that is set up, you can right-click your script tool to expose its parameters in the model. The script needs to handle input and output parameters like this:

import arcpy
string = arcpy.GetParameterAsText(0)
import shutil
shutil.copy("c:/chris/Test1/CitizenComments.mxd",
            "c:/chris/test2/{}CitizenComments.mxd".format(string))
arcpy.SetParameterAsText(1,  "c:/chris/test2/{}CitizenComments.mxd".format(string)))

Then, set your script tool with an input parameter of type String and a derived parameter of type File. Then re-add your tool to ModelBuilder and I think you'll get what you're looking for.

Or, you can avoid having to set up a separate script tool by using the very useful Calculate Value model-only tool -- a little Python goes a long way in ModelBuilder! You can get this tool added to your model with a right click.

Expression:

CopyFile(r"%String%")

Code Block

import shutil
def CopyFile(string):
  shutil.copy("c:/chris/Test1/CitizenComments.mxd",
              "c:/chris/test2/{}CitizenComments.mxd".format(string))
  return "c:/chris/test2/{}CitizenComments.mxd".format(string)

Data Type

File

Set your parameter String as type String and use the magic wand tool to make it a precondition to Calculate Value, and you're good to go!'

This is how you use a value twice in a format string. The way to debug this kind of thing is to find a Python prompt (the one in ArcMap will do) and type stuff at it:

>>> "{} {}".format("foo")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IndexError: tuple index out of range
>>> "{} {}".format("foo", "foo")
'foo foo'
>>> "{} {}".format("foo", "bar")
'foo bar'
>>> "{0} {0}".format("foo")
'foo foo'

import os
import shutil
def CopyFile(string):
   os.mkdir("c:/chris/{}.format(string))
   shutil.copy("c:/chris/Test1/CitizenComments.mxd",
                     "c:/chris/{0}/{0}CitizenComments.mxd".format(string))
   return "c:/chris/{0}/{0}CitizenComments.mxd".format(string)

Thanks Curtis, following your advice I was able to get the copy file working using:

If I wanted to modify the code block to first create a folder with the same name as what is appended to the copied CitizenComments.mxd file what would need to be changed? So for example the new file path would be C:\chris\105\105CitizenComments.mxd

I had tried the following based on the previous copy file code, but obviously I'm missing some stuff:

import os
import shutil
def CopyFile(string):
   os.mkdir("c:/chris/{}.format(string))
   shutil.copy("c:/chris/Test1/CitizenComments.mxd",
                     "c:/chris/{}/{}CitizenComments.mxd".format(string))
   return "c:/chris/{}/{}CitizenComments.mxd".format(string)

Thanks Curtis, I'll check this out.

Thanks Darren. I'll play around with your suggestions.

Have a good weekend.

The most straightforward way would be something like the following, although you may run into trouble with /" (untested):

import shutil
index = arcpy.GetParameterAsText(0) # get the first input parameter entered into the tool dialog
shutil.copy("c:/chris/Test1/CitizenComments.mxd" , "c:/chris/test2/" + index + "CitizenComments.mxd")

To better work with paths, use os.path.join:

import shutil, os
index = arcpy.GetParameterAsText(0) # get the first input parameter entered into the tool dialog
shutil.copy("c:/chris/Test1/CitizenComments.mxd" , os.path.join("c:/chris/test2", index + "CitizenComments.mxd")

Oh ya, as you can tell: new to python
