ansible we cant create functions. we can use existing filters...

filter = data transformation/manipulation

devops --> DevOps
aws --> AWS

if a number less than 10, print less than 10
otherwise print greater than equal to 10.

number < 10

Ansible is strict, it can't automatically convert text into number

10 --> text

ansible filters are useful. ansible developed in python...

filter is denoted by | (pipe symbol)

dictionary=map=key/value

course: devops
trainer: sivakumar
duration: 120hrs

items==list


[
{'key': 'Course', 'value': 'Ansbile'}, 
{'key': 'Trainer', 'value': 'Sivakumar'}, 
{'key': 'Duration', 'value': '120hr'}
]
