Redirect to file directory does not exist

Question

I call this command in Python:

os.system('echo %s  > `find $HOME -iname p410.yaml`' % string)

This works fine on OSX, but on Ubuntu it gives me /home/path/to/p410.yaml: Directory nonexistent. However, I can edit the file along the path that it gave me using vim.

Any idea what?

EDIT

Output from stat find $HOME -iname p410.yaml

Answer 1

The problem was that there were two files with the same name that were slightly obscured through the error messages that were passed through the Python interpreter. Honestly, I am also surprised that when I called vim 'find $HOME -iname p410.yaml', it worked when there were two options for opening a file.
