I am using yaml file to store attribute and value. But some of the values need the current date to be appended.
So how do I enter the v开发者_运维技巧alue in yaml file, so that yaml parser can automatically recognise and substitute with current date
I am using pyyaml and python
pyyaml does not automatically substitute anything. Just use a custom string e.g. ${now}
and replace it with the current date after parsing the yaml file.
For example,
value.replace("${now}", datetime.date.today().isoformat())
where value
is a sting read from the input file.
