Setup

To use it, you need three things:

1. A Python 3 interpreter
2. Metview 5 needs to be in your PATH
3. Metview's Python module needs to be in your PYTHONPATH

So, to try it right now, do the following from a terminal:

module load python3/new
module swap metview/new
export PYTHONPATH=/tmp/cgi/install/python/lib/python3.6/site-packages/:$PYTHONPATH

Test it

Here's a quick Python program to check that it's working. Copy this into a file called test-metview.py

import metview as mv


# call Metview's built-in function to return a lower case string
print(mv.lowercase('Hello World!')) # should output "hello world!"

and run it like this:

python3 test-metview.py

If this works, then you have successfully set up Metview's Python interface!
