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.

Hi all,

I am trying to run a simple python script using python resource of
chef-cookbook. Here is what my recipe looks like:

filename = "test.py"
python "excute_file" do
 cwd '/home/peeyush/'
 code <<-EOH
python #{filename}
 EOH
 action :run
end

The error I am getting is:

Recipe: hellochef::default

I am not sure what I am doing wrong as there is no example to run a python
script. Please help me resolve this issue.
