[chef] Re: Error in running python script through python resource.

["Julian C. Dunn" < >]

You are generating a python script that contains the code

python test.py

which will cause an error when passed to the Python interpreter:

$ cat test.py
python test.py
$ python test.py
  File "test.py", line 1
    python test.py
             ^
SyntaxError: invalid syntax

If you want to execute an external script, just use the 'execute'
resource. However, if you want to execute in-line python, then just
write the Python code in the "code" attribute.
