After reading some articles and blog posts I found out that:

%-format method is a very old method for interpolation and is not recommended to use as it decreases the code readability.
In str.format() method we pass the string object to the format() function for string interpolation.
In the template method, we make a template by importing template class from built-in string module.
Literal String Interpolation method is powerful interpolation method which is easy to use and increase the code readability.

I am still figuring out the best practices but I personally like the f syntax.

And yes learning python is a real joy. Hope I keep getting better at it :) Thanks for reading the blog.

Yeah me too. f'{}...' usually meets my needs and I only use format when I need to use printf style formatting or the expression I want to print is complex enough to impact readability inside a simple interpolation.

I believe the %-format approach is from python2 and str.format() is preferred in python3. You still see it a lot though.
