how can i echo a line containing single quotes?

I want to echo a line containing single quotes but when I am echoing it, the output comes out without the quotes inside that line. I am using this echo rule_files: [ '${path.config}/folder/*.py' ] and the output is

rule_files: [ ${path.config}/folder/*.py ]

I want the output to include the single quotes around the path.

Answer

You have to escape the quotes:

echo rule_files: [ '${path.config}/folder/*.py' ]

or

echo rule_files: [ ''${path.config}/folder/*.py'' ]
