In the praise of

The more common expression is "in praise of."
Can you provide us with the (full) sentence you have in mind?

Actually, I am a computer programmer, and I want to write a comment above every function I write. So, for that I want write comment like
//In the praise of : This method is used for Getting the initial data of country names, and It is stopping the app, if its update is available. And also stopping the app, if any error.

So, I think In case of 'In praise of ' I can use, // I am writing this method because: It is giving me the country names, and doing the work...etc...

Any good word I can use to start this comment.

Anonymous//In the praise of :

I don't know of a computer language that allows spaces in method names. Usually white space is a delimiter, and extra white space is ignored by the compiler or interpreter.

Anonymous//In the praise of : This method is used for Getting the initial data of country names, and It is stopping the app, if its update is available. And also stopping the app, if any error.

I think you are not structuring your code very well if one method does all of those functions.
The purpose of comments is to inform the people who have to maintain
