[SOLVED] New to python fabric and not able to run basic code

I have a basic code which doesn't run:

def hello():
    print("uptime")

When I run the following command in terminal fab hello

I get this error:

No idea what 'hello' is!

The issue is that the new fabric task method (as discussed here - http://docs.fabfile.org/en/1.14/usage/tasks.html) is to use the @task decorator. The equivalent example for your code is:

from fabric import task

@task
def hello():
  print("uptime")

Running fab hello should yield the expected output.
